Accounting Policies [Abstract]
Basis of financial statement preparation [Text Block]	Basis of Financial Statement Preparation The condensed consolidated financial statements present the financial position, results of operations and cash flows of The Davey Tree Expert Company and its subsidiaries. When we refer to “we,” “us,” “our,” the "Company," “Davey,” or “Davey Tree”, we mean The Davey Tree Expert Company and its subsidiaries, unless otherwise expressly stated or the context indicates otherwise. We have prepared the accompanying unaudited condensed consolidated financial statements in accordance with accounting principles generally accepted in the United States (“U.S. GAAP”), as codified in the Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”), and with the rules and regulations of the Securities and Exchange Commission (“SEC”) for interim financial information. The condensed consolidated financial statements include all adjustments which, in the opinion of management, are necessary for a fair presentation of the results for the interim periods presented. All such adjustments are of a normal, recurring nature. All intercompany accounts and transactions have been eliminated in consolidation. Certain information and disclosures required by U.S. GAAP for complete financial statements have been omitted in accordance with the rules and regulations of the SEC. We suggest that these condensed consolidated financial statements be read in conjunction with the financial statements included in our annual report on Form 10-K for the year ended December 31, 2021 (the “2021 Annual Report”). Per Common Share Information-- Prior year common share and per share data have been retroactively adjusted to recognize a two-for-one stock split of our common shares effective October 1, 2021. Use of Estimates in Financial Statement Preparation --The preparation of financial statements in accordance with U.S. GAAP requires the use of estimates and assumptions that affect reported amounts. Our condensed consolidated financial statements include amounts that are based on management’s best estimates and judgments. Estimates are used for, but not limited to, accounts receivable valuation, depreciable lives of fixed assets, long-lived asset valuation, self-insurance accruals, income taxes, stock valuation and revenue recognition. Actual results could differ from those estimates. While the coronavirus ("COVID-19") pandemic did not have a material adverse effect on our reported results for the first three months of our 2022 fiscal year, the overall extent and duration of the impact of COVID-19 on businesses and economic activity generally remains unclear. The extent to which our operations may be impacted by COVID-19 will depend largely on future developments, which are highly uncertain due to its continual evolution, such as resurgences in cases and the emergence of new strains of COVID-19, and cannot be accurately predicted, including new information which may emerge concerning the severity of the outbreak and actions by government authorities to contain the pandemic or treat its impact, including reimposing previously-lifted measures and the possibility additional measures will be put in place, among other things. Our business continues to be impacted by a number of other macro-economic factors, in addition to the trailing impact of the COVID-19 pandemic. Global supply chains and product availability remain highly challenged and recent global events in Eastern Europe have only exacerbated an already difficult operating environment. These factors, combined with higher fuel costs and a highly competitive labor market, have created an inflationary environment and cost pressures. The Company’s fiscal quarters each contain thirteen operating weeks, with the exception of the fourth quarter of a 53-week fiscal year, which contains fourteen operating weeks. The Company’s fiscal quarter that ended April 2, 2022 is referred to as the first quarter of 2022, and the fiscal quarter ended April 3, 2021 is referred to as the first quarter of 2021. Recent Accounting Guidance Accounting Standard Not Yet Adopted Accounting Standards Update 2020-04, Reference Rate Reform (Topic 848) --In March 2020, the FASB issued ASU 2020-04, "Reference Rate Reform (Topic 848)—Facilitation of the Effects of Reference Rate Reform on Financial Reporting". The guidance of this ASU is designed to provide relief from the accounting analysis and impacts that may otherwise be required for modifications to agreements (e.g., loans, debt securities, derivatives, borrowings) necessitated by reference rate reform. It also provides optional expedients to enable companies to continue to apply hedge accounting to certain hedging relationships impacted by reference rate reform. Application of the guidance is optional, is only available in certain situations, and is only available for companies to apply until December 31, 2022. The Company is currently reviewing its agreements impacted by the reference rate reform and does not expect this ASU to have a material impact to the Company’s financial statements.

Under certain circumstances, the amount available under the revolving credit facility may be increased to $425,000. The revolving credit facility contains certain affirmative and negative covenants customary for this type of facility and includes financial covenant ratios with respect to a maximum leverage ratio (not to exceed 3.00 to 1.00 with exceptions in case of material acquisitions) and a minimum interest coverage ratio (not less than 3.00 to 1.00), in each case subject to certain further restrictions as described in the credit agreement.

The 3.99% Senior Notes were issued pursuant to a Note Purchase and Private Shelf Agreement (the “Note Purchase and Shelf Agreement”) between the Company, PGIM, Inc. and the purchasers of the 3.99% Senior Notes, which was amended in September 2021. Among other things, the amendment increased the total facility limit to $150,000 and extended the issuance period for subsequent series of promissory notes to be issued and sold pursuant to the Note Purchase and Shelf Agreement to September 2024. The amendment also amended certain provisions and covenants to generally conform them to the corresponding provisions and covenants in the amended and restated revolving credit agreement. In addition, the amendment and restatement of the revolving credit agreement in August 2021 provided that the Company is permitted to incur indebtedness arising under the Note Purchase and Shelf Agreement in an aggregate principal amount not to exceed $150,000. As the Company has previously issued notes in an aggregate amount of $75,000 under the Note Purchase and Shelf Agreement, it now has capacity to issue subsequent series of promissory notes pursuant to the Note Purchase and Shelf Agreement (the "Shelf Notes") in an aggregate amount of up to $75,000. The 3.99% Senior Notes are equal in right of payment with our revolving credit facility and all other senior unsecured obligations of the Company. Interest is payable semiannually and five equal, annual principal payments commence on September 21, 2024 (the sixth anniversary of issuance). The Note Purchase and Shelf Agreement contains customary events of default and covenants related to limitations on indebtedness and transactions with affiliates and the maintenance of certain financial ratios. The Company may prepay at any time all, or from time to time any part of, the outstanding principal amount of the 3.99% Senior Notes, subject to the payment of a make-whole amount. 4.00% Senior Unsecured Notes --On February 5, 2019, we issued 4.00% Senior Notes, Series B (the "4.00% Senior Notes") pursuant to the Note Purchase and Shelf Agreement in the aggregate principal amount of $25,000. The 4.00% Senior Notes are due September 21, 2028. The 4.00% Senior Notes are equal in right of payment with our revolving credit facility and all other senior unsecured obligations of the Company. Interest is payable semiannually and five equal, annual principal payments commence on September 21, 2024. The net proceeds of all senior notes were used to pay down borrowings under our revolving credit facility. Term loans --Periodically, the Company will enter into term loans for the procurement of insurance or to finance acquisitions. Aggregate Maturities of Long-Term Debt --Aggregate maturities of long-term debt based on the principal amounts outstanding at April 2, 2022 were as follows: 2022--$13,080; 2023--$1,530; 2024--$15,940; 2025--$15,042; 2026--$85,781; 2027--$0; and thereafter $30,000. Accounts Receivable Securitization Facility --In May 2021, the Company amended its Accounts Receivable Securitization Facility (the "AR Securitization program") to extend the scheduled termination date for an additional one year period, to June 30, 2022. In addition to extending the termination date, the amendment included a change to the letter of credit ("LC") issuance fee payable under the terms of the agreement, as described below. The AR Securitization program has a limit of $100,000, of which $83,355 was issued for LCs as of both April 2, 2022 and December 31, 2021. Under the AR Securitization program, Davey Tree transfers by selling or contributing current and future trade receivables to a wholly-owned, bankruptcy-remote financing subsidiary which pledges a perfected first priority security interest in the trade receivables--equal to the issued LCs as of April 2, 2022--to the bank in exchange for the bank issuing LCs. Fees payable to the bank include: (a) an LC issuance fee, payable on each settlement date, in the amount of .90% per annum (1.00% prior to the May 2021 amendment) on the aggregate amount of all LCs outstanding plus outstanding reimbursement obligations (e.g., arising from drawn LCs), if any, and (b) an unused LC fee, payable monthly, equal to (i) .35% per annum for each day on which the sum of the total LCs outstanding plus any outstanding reimbursement obligations is greater than or equal to 50% of the facility limit and (ii) .45% per annum for each day on which the sum of the total LCs outstanding plus any outstanding reimbursement obligations is less than 50% of the facility limit. If an LC is drawn and the bank is not immediately reimbursed in full for the drawn amount, any outstanding reimbursement obligation will accrue interest at a per annum rate equal to a reserve-adjusted LIBOR or, in certain circumstances, a base rate equal to the higher of (i) the bank’s prime rate and (ii) the federal funds rate plus .50% and, following any default, 2.00% plus the greater of (a) adjusted LIBOR and (b) a base rate equal to the higher of (i) the bank’s prime rate and (ii) the federal funds rate plus .50%. The agreements underlying the AR Securitization program contain various customary representations and warranties, covenants, and default provisions which provide for the termination and acceleration of the commitments under the AR Securitization program in circumstances including, but not limited to, failure to make payments when due, breach of a representation, warranty or covenant, certain insolvency events or failure to maintain the security interest in the trade receivables, and defaults under other material indebtedness. Total Commitments Related to Issued Letters of Credit --As of April 2, 2022, total commitments related to issued LCs were $88,365, of which $2,877 were issued under the revolving credit facility, $83,355 were issued under the AR Securitization program, and $2,133 were issued under short-term lines of credit. As of December 31, 2021, total commitments related to issued LCs were $88,362, of which $2,877 were issued under the revolving credit facility, $83,355 were issued under the AR Securitization program, and $2,130 were issued under short-term lines of credit. As of April 2, 2022, we were in compliance with all debt covenants.

Leases [Abstract]
Leases	Leases We lease certain office and parking facilities, warehouse space, equipment, vehicles and information technology equipment under operating and finance leases. Lease expense for these leases is recognized within the Condensed Consolidated Statements of Operations on a straight-line basis over the lease term, with variable lease payments recognized in the period those payments are incurred.

We often have options to renew lease terms for buildings and other assets. The exercise of lease renewal options is generally at our sole discretion. In addition, certain lease agreements may be terminated prior to their original expiration date at our discretion. We evaluate each renewal and termination option at the lease commencement date to determine if we are reasonably certain to exercise the option on the basis of economic factors. The weighted average remaining lease terms as of April 2, 2022 was 3.8 years for operating leases and 4.8 years for finance leases. The discount rate implicit within our leases is generally not determinable and therefore the Company determines the discount rate based on its incremental borrowing rate. The incremental borrowing rate for each lease is determined based on its term and the currency in which lease payments are made, adjusted for the impacts of collateral. The weighted average discount rates used to measure our lease liabilities as of April 2, 2022 was 2.42% for operating leases and 2.14% for finance leases.

Stock-Based Compensation

Stock-Based Compensation	3 Months Ended
	Apr. 02, 2022
Share-based Payment Arrangement [Abstract]
Stock-based compensation[Text Block]	Stock-Based CompensationOur shareholders approved the 2014 Omnibus Stock Plan (the “2014 Stock Plan”) at our annual meeting of shareholders on May 20, 2014. The 2014 Stock Plan replaced the expired 2004 Omnibus Stock Plan (the “2004 plan”) previously approved by the shareholders in 2004. The 2014 Stock Plan is administered by the Compensation Committee of the Board of Directors and has a term of ten years. All directors of the Company and employees of the Company and its subsidiaries are eligible to participate in the 2014 Stock Plan. The 2014 Stock Plan (similar to the 2004 plan) continues the maintenance of the Employee Stock Purchase Plan, as well as provisions for the grant of stock options and other stock-based incentives. The 2014 Stock Plan provides for the grant of five percent of the number of the Company’s common shares outstanding as of the first day of each fiscal year plus the number of common shares that were available for grant of awards, but not granted, in prior years. In no event, however, may the number of common shares available for the grant of awards in any fiscal year exceed ten percent of the common shares outstanding as of the first day of that fiscal year. Common shares subject to an award that is forfeited, terminated, or canceled without having been exercised are generally added back to the number of shares available for grant under the 2014 Stock Plan. Stock-based compensation expense under all share-based payment plans -- our Employee Stock Purchase Plan, stock option plans, stock-settled stock appreciation rights ("SSARs") and restricted stock units ("RSUs") -- was included in the results of operations as follows: Three Months Ended April 2, April 3, Compensation expense, all share-based payment plans $ 1,270 $ 891 Stock-based compensation consisted of the following: Employee Stock Purchase Plan --Under the Employee Stock Purchase Plan, all full-time employees with one year of service are eligible to purchase, through payroll deduction, common shares. Employee purchases under the Employee Stock Purchase Plan are at 85% of the fair market value of the common shares--a 15% discount. We recognize compensation costs as payroll deductions are made. The 15% discount of total shares purchased under the plan resulted in compensation cost of $452 being recognized for the three months ended April 2, 2022 and $357 for the three months ended April 3, 2021. Stock Option Plans --The stock options outstanding were awarded under a graded vesting schedule, measured at fair value, and have a term of ten years. Compensation costs for stock options are recognized over the requisite service period on the straight-line recognition method. Compensation cost recognized for stock options was $99 for the three months ended April 2, 2022 and $125 for the three months ended April 3, 2021. Beginning in 2021, management and the Compensation Committee replaced the issuance of stock options with performance-based restricted stock units ("PRSUs") for certain employees. Stock-Settled Stock Appreciation Rights -- A SSAR is an award that allows the recipient to receive common shares equal to the appreciation in the fair market value of our common shares between the date the award was granted and the conversion date of the shares vested. Effective January 1, 2019, management and the Compensation Committee replaced the issuance of future SSARs with PRSUs for certain management employees. The following table summarizes our SSARs as of April 2, 2022. Stock-Settled Number Weighted- Weighted- Unrecognized Aggregate Unvested, January 1, 2022 87,534 $ 1.92 Granted — — Forfeited — — Vested (43,752) 1.92 Unvested, April 2, 2022 43,782 $ 1.92 0.7 years $ 63 $ 792 Compensation costs for SSARs are determined using a fair-value method and amortized over the requisite service period. “Intrinsic value” is defined as the amount by which the fair market value of a common share exceeds the grant date price of a SSAR. Compensation expense for SSARs was $21 for the three months ended April 2, 2022 and $41 for the three months ended April 3, 2021. Restricted Stock Units --During the three months ended April 2, 2022, the Compensation Committee awarded 123,869 PRSUs to certain management employees. The Compensation Committee made similar awards in prior periods. The awards vest over specified periods. The following table summarizes PRSUs and RSUs as of April 2, 2022. Restricted Stock Units Number Weighted- Weighted- Unrecognized Aggregate Unvested, January 1, 2022 740,160 $ 12.49 Granted 123,869 17.89 Forfeited — — Vested (91,508) 8.50 Unvested, April 2, 2022 772,521 $ 13.83 2.2 years $ 7,075 $ 13,983 Employee PRSUs 705,629 $ 13.99 2.3 years $ 6,745 $ 12,772 Nonemployee Director RSUs 66,892 $ 12.20 0.9 years $ 330 $ 1,211 Compensation cost for PRSUs and RSUs is determined using a fair-value method and amortized on the straight-line recognition method over the requisite service period. “Intrinsic value” is defined as the amount by which the fair market value of a common share exceeds the grant date price of a PRSU or an RSU. Compensation expense on PRSUs and RSUs totaled $698 for the three months ended April 2, 2022 and $368 for the three months ended April 3, 2021. We estimated the fair value of each stock-based award on the date of grant using a binomial option-pricing model. The binomial model considers a range of assumptions related to volatility, risk-free interest rate and employee exercise behavior. Expected volatilities utilized in the binomial model are based on historical volatility of our stock prices and other factors. Similarly, the dividend yield is based on historical experience and expected future changes. The binomial model also incorporates exercise and forfeiture assumptions based on an analysis of historical data. The expected life of the stock-based awards is derived from the output of the binomial model and represents the period of time that awards granted are expected to be outstanding. The fair values of stock-based awards granted were estimated at the dates of grant with the following weighted-average assumptions. Three Months Ended April 2, April 3, Volatility rate 9.7 % 9.9 % Risk-free interest rate 1.6 % .3 % Expected dividend yield .4 % .4 % Expected life of awards (years) 3.0 3.0 General Stock Option Information --The following table summarizes activity under the stock option plans for the three months ended April 2, 2022. Stock Options Number Weighted- Weighted- Aggregate Outstanding, January 1, 2022 2,350,934 $ 8.56 Granted — — Exercised (42,407) 8.16 Forfeited — — Outstanding, April 2, 2022 2,308,527 $ 8.56 4.6 years $ 22,023 Exercisable, April 2, 2022 1,718,797 $ 7.74 3.7 years $ 17,801 As of April 2, 2022, there was approximately $705 of unrecognized compensation cost related to stock options outstanding. The cost is expected to be recognized over a weighted-average period of 1.8 years. “Intrinsic value” is defined as the amount by which the market price of a common share exceeds the exercise price of an option. Common shares are issued from treasury upon the exercise of stock options and SSARs, the vesting of RSUs and PRSUs or purchases under the Employee Stock Purchase Plan.

Income Taxes

Income Taxes	3 Months Ended
	Apr. 02, 2022
Income Tax Disclosure [Abstract]
Income taxes [Text Block]	Income Taxes Our income tax provision for interim periods is determined using an estimate of our annual effective tax rate adjusted for discrete items, if any, that are taken into account in the relevant period. Each quarter we update our estimate of the annual effective tax rate and, if our estimated annual tax rate changes, we make a cumulative adjustment. The estimated annual effective tax rate for the three months ended April 2, 2022 was 27.7%. Our actual effective tax rate was 11.0% and 22.6% for the three months ended April 2, 2022 and April 3, 2021, respectively. The change in the effective tax rate from statutory tax rates was primarily due to the impact of favorable discrete items which are a set amount and therefore have a larger impact on the rate based on our net income before tax in the first quarter compared to the impact it will have on the rate for the full year. As of April 2, 2022, we had unrecognized tax benefits of $719, of which $346 would affect our effective rate if recognized, and accrued interest expense related to unrecognized benefits of $59. At December 31, 2021, we had unrecognized tax benefits of $700, of which $327 would affect our effective rate if recognized, and accrued interest expense related to unrecognized benefits of $56. Unrecognized tax benefits are the differences between a tax position taken, or expected to be taken, in a tax return, and the benefit recognized for financial reporting purposes. We recognize interest accrued related to unrecognized tax benefits in income tax expense. Penalties, if incurred, would be recognized as a component of income tax expense.

Equity [Abstract]
Per share amounts and common and redeemable shares outstanding [Text Block]	Per Share Amounts and Common and Redeemable Shares Outstanding We calculate our basic earnings per share by dividing net income or net loss by the weighted average number of common shares outstanding during the period. Diluted earnings per share are calculated in a similar manner, but include the effect of dilutive securities. To the extent these securities are antidilutive, they are excluded from the calculation of earnings per share. The per share amounts were computed as follows (Adjusted for the two-for-one stock split of our common shares effective October 1, 2021): Three Months Ended April 2, April 3, Income available to common shareholders: Net income $ 1,782 $ 4,427 Weighted-average shares (in thousands): Basic: Basic weighted-average shares 44,618 45,682 Diluted: Basic from above 44,618 45,682 Incremental shares from assumed: Exercise of stock options and awards 2,220 2,234 Diluted weighted-average shares 46,838 47,916 Net income per share: Basic $ .04 $ .10 Diluted $ .04 $ .09 Common and Redeemable Shares Outstanding -- A summary of the activity of the common and redeemable shares outstanding for the three months ended April 2, 2022 was as follows: Common Redeemable Total Shares outstanding at January 1, 2022 35,110,432 9,391,790 44,502,222 Shares purchased (320,255) (69,260) (389,515) Shares sold 210 295,977 296,187 Options and awards exercised 117,718 — 117,718 Shares outstanding at April 2, 2022 34,908,105 9,618,507 44,526,612 On April 2, 2022, we had 44,526,612 common and redeemable shares outstanding and employee options exercisable to purchase 1,718,797 common shares. Common Stock Split-- On September 17, 2021, our board of directors approved and declared a two-for-one stock split in the form of a stock dividend, pursuant to which each of our shareholders of record at the close of business on October 1, 2021 received one additional common share for each then-held common share, which was paid on October 15, 2021. On September 20, 2021, in connection with the stock split, the Company filed a Certificate of Amendment to its 2017 Amended Articles of Incorporation with the Secretary of State of the State of Ohio, which became effective upon filing and (1) proportionately increased the authorized number of common shares from 48,000,000 to 96,000,000 and (2) proportionately decreased the par value of our common shares from $1.00 per share to $.50 per share. 2022 Subscription Offering Beginning April 2022, the Company is offering to eligible employees and nonemployee directors the right to subscribe to a maximum of 2,666,667 common shares of the Company at $18.10 per share in accordance with the provisions of The Davey Tree Expert Company 2014 Omnibus Stock Plan and the rules of the Compensation Committee of the Company’s Board of Directors.

Revenue Recognition [Abstract]
Revenue from contract from customer [Text Block]	Revenue Recognition We recognize revenue in accordance with ASC Topic 606, Revenue from Contracts with Customers. Nature of Performance Obligations and Significant Judgments At contract inception, the Company assesses the goods and services promised in its contracts with customers and identifies a performance obligation for each promised good or service (or bundle of goods and services) that is distinct. To identify the performance obligations, the Company considers each of the goods or services promised in the contract regardless of whether they are explicitly stated or are implied by customary business practices. Our contracts with our customers generally originate upon the completion of a quote for services for residential and commercial customers or the receipt of a purchase order (or similar work order) for utility customers. In some cases, our contracts are governed by master services agreements, in which case our contract under ASC 606 consists of the combination of the master services agreement and the quote/purchase order. Many of our contracts have a stated duration of one year or less or contain termination clauses that allow the customer to cancel the contract after a specified notice period, which is typically less than 90 days. Due to the fact that many of our arrangements allow the customer to terminate for convenience, the duration of the contract for revenue recognition purposes generally does not extend beyond the services that we have actually transferred. As a result, many of our contracts are, in effect, day-to-day or month-to-month contracts. Disaggregation of Revenue The following tables disaggregate our revenue for the three months ended April 2, 2022 and April 3, 2021 by major sources: Three Months Ended April 2, 2022 Utility Residential All Other Consolidated Type of service: Tree and plant care $ 136,959 $ 81,634 $ (42) $ 218,551 Grounds maintenance — 31,596 — 31,596 Storm damage services 1,634 1,550 — 3,184 Consulting and other 66,574 22,151 588 89,313 Total revenues $ 205,167 $ 136,931 $ 546 $ 342,644 Geography: United States $ 196,443 $ 128,239 $ 546 $ 325,228 Canada 8,724 8,692 — 17,416 Total revenues $ 205,167 $ 136,931 $ 546 $ 342,644 Three Months Ended April 3, 2021 Utility Residential All Other Consolidated Type of service: Tree and plant care $ 123,967 $ 71,965 $ (163) $ 195,769 Grounds maintenance — 29,799 — 29,799 Storm damage services 4,113 1,183 — 5,296 Consulting and other 45,773 21,560 624 67,957 Total revenues $ 173,853 $ 124,507 $ 461 $ 298,821 Geography: United States $ 163,684 $ 115,882 $ 461 $ 280,027 Canada 10,169 8,625 — 18,794 Total revenues $ 173,853 $ 124,507 $ 461 $ 298,821 Contract Balances Our contract liabilities consist of advance payments and billings in excess of costs incurred and deferred revenue.

Fair Value Disclosures [Abstract]
Fair value measurements and financial instruments	Fair Value Measurements and Financial Instruments FASB ASC 820, “Fair Value Measurements and Disclosures" (“Topic 820”) defines fair value based on the price that would be received to sell an asset or the exit price that would be paid to transfer a liability in an orderly transaction between market participants at the measurement date. Market participants are defined as buyers or sellers in the principal or most advantageous market for the asset or liability that are independent of the reporting entity, knowledgeable and able and willing to transact for the asset or liability. Valuation Hierarchy --Topic 820 establishes a fair value hierarchy that prioritizes observable and unobservable inputs used to measure fair value. The hierarchy prioritizes the inputs into three broad levels: Level 1 inputs are quoted prices in active markets for identical assets or liabilities that the entity has the ability to access. Level 2 inputs are observable inputs other than prices included in Level 1, such as quoted prices for similar assets and liabilities in active markets; quoted prices for identical or similar assets and liabilities in markets that are not active; or other inputs that are observable or can be corroborated with observable market data. Level 3 inputs are unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets and liabilities. This includes certain pricing models, discounted cash flow methodologies and similar techniques that use significant unobservable inputs. Our assets and liabilities measured at fair value on a recurring basis at April 2, 2022 were as follows: Fair Value Measurements at April 2, 2022 Using: Assets and Liabilities Recorded at Total Carrying Value at April 2, 2022 Quoted Significant Significant Assets: Assets invested for self-insurance Certificates of deposits, current $ 3,750 $ 3,750 $ — $ — Certificates of deposits, noncurrent 10,109 10,109 — — Available-for-sale debt securities: United States Government and agency securities 5,068 5,068 — — Corporate notes and bonds 294 294 — — Total available-for-sale debt securities 5,362 5,362 — — Marketable equity securities: Mutual funds - domestic 10,961 10,961 — — Corporate stocks - domestic 2,579 2,579 — — Corporate stocks - foreign 73 73 — — Exchange traded funds - domestic 5,410 5,410 — — Exchange traded funds - foreign 463 463 — — Total marketable equity securities 19,486 19,486 — — Liabilities: Deferred compensation $ 4,726 $ — $ 4,726 $ — Our assets and liabilities measured at fair value on a recurring basis at December 31, 2021 were as follows: Fair Value Measurements at December 31, 2021 Using: Assets and Liabilities Recorded at Total Carrying Value at December 31, 2021 Quoted Significant Significant Assets: Assets invested for self-insurance Certificates of deposits, current $ 4,250 $ 4,250 $ — $ — Certificates of deposits, noncurrent 10,609 10,609 — — Available-for-sale debt securities: United States Government and agency securities 3,230 3,230 — — Corporate notes and bonds 176 176 — — Total available-for-sale debt securities 3,406 3,406 — — Marketable equity securities: Mutual funds - domestic 7,476 7,476 — — Corporate stocks - domestic 1,877 1,877 — — Corporate stocks - foreign 57 57 — — Exchange traded funds - domestic 1,491 1,491 — — Exchange traded funds - foreign 485 485 — — Total marketable equity securities 11,386 11,386 — — Liabilities: Deferred compensation $ 4,333 $ — $ 4,333 $ — The assets invested for self-insurance are certificates of deposit, stocks, bonds, mutual funds and exchange traded funds--classified as Level 1--based on quoted market prices of the identical underlying securities in active markets. The estimated fair value of the deferred compensation--classified as Level 2--is based on the value of the Company's common shares, determined by independent valuation. Fair Value of Financial Instruments --The fair values of our current financial assets and current liabilities, including cash, accounts receivable, accounts payable, and accrued expenses, among others, approximate their reported carrying values because of their short-term nature. Financial instruments classified as noncurrent assets and liabilities and their carrying values and fair values were as follows: April 2, 2022 December 31, 2021 Carrying Fair Carrying Fair Assets: Available-for-sale debt securities $ 5,362 $ 5,362 $ 3,406 $ 3,406 Marketable equity securities 19,486 19,486 11,386 11,386 Liabilities: Revolving credit facility, noncurrent $ 70,781 $ 70,781 $ 46,832 $ 46,832 Senior unsecured notes, noncurrent 75,000 82,293 75,000 78,432 Term loans, noncurrent 1,623 1,620 2,373 2,431 Total $ 147,404 $ 154,694 $ 124,205 $ 127,695 The carrying value of our revolving credit facility approximates fair value--classified as Level 2--as the interest rates on the amounts outstanding are variable. The fair value of our senior unsecured notes and term loans--classified as Level 2--is determined based on expected future weighted-average interest rates with the same remaining maturities. Market Risk-- In the normal course of business, we are exposed to market risk related to changes in foreign currency exchange rates, changes in interest rates and changes in fuel prices. We do not hold or issue derivative financial instruments for trading or speculative purposes. In prior years, we have used derivative financial instruments to manage risk, in part, associated with changes in interest rates and changes in fuel prices. Presently, we are not engaged in any hedging or derivative activities. Changes in the fair values of available-for-sale debt securities that are determined to be holding gains or losses are recorded through accumulated other comprehensive income (loss) net of applicable taxes, within shareholders' equity. In assessing whether a credit loss exists, we evaluate our ability to hold the investment, the strength of the underlying collateral and the extent to which the investment's amortized cost or cost, as appropriate, exceeds its related fair value. We held approximately 19,486 and 11,386 in marketable equity securities as of April 2, 2022 and December 31, 2021, respectively. Realized and unrealized gains and losses on marketable equity securities are included in other income (expense) in the Consolidated Statements of Operations.

Commitments and Contingencies Disclosure [Abstract]
Commitments and contingencies [Text Block]	Commitments and ContingenciesWe are party to a number of lawsuits, threatened lawsuits and other claims arising out of the normal course of business. On a quarterly basis, we assess our liabilities and contingencies in connection with outstanding legal proceedings utilizing the latest information available. Where it is probable that we will incur a loss and the amount of the loss can be reasonably estimated, we record a liability in our consolidated financial statements. These legal accruals may be increased or decreased to reflect any relevant developments on a quarterly basis. Where a loss is not probable or the amount of the loss is not estimable, we do not record a legal accrual, consistent with applicable accounting guidance. Based on information currently available to us, advice of counsel, and available insurance coverage, we believe that our established accruals are adequate and the liabilities arising from the legal proceedings will not have a material adverse effect on our consolidated financial condition. We note, however, that in light of the inherent uncertainty in legal proceedings, there can be no assurance that the ultimate resolution of a matter will not exceed established accruals. As a result, the outcome of a particular matter or a combination of matters may be material to our results of operations for a particular period, depending upon the size of the loss or our income for that particular period. In November 2017, a suit was filed in Savannah, Georgia state court ("State Court") against Davey Tree, its subsidiary, Wolf Tree, Inc. ("Wolf Tree"), a former Davey employee, two Wolf Tree employees, and a former Wolf Tree employee alleging various acts of negligence and seeking compensatory and punitive damages for wrongful death and assault and battery of the plaintiff’s husband, a Wolf Tree employee, who was shot and killed in August 2017. In July 2018, a related survival action was filed by the deceased’s estate against Davey Tree, its subsidiary, Wolf Tree, and four current and former employees in Savannah, Georgia, which arises out of the same allegations, seeks compensatory and punitive damages and also includes three Racketeer Influenced and Corrupt Organizations Act ("RICO") claims under Georgia law seeking compensatory damages, treble damages, and punitive damages. The 2018 case was removed to the United States District Court for the Southern District of Georgia, Savannah Division ("Federal Court"), on August 2, 2018. The Company filed a motion to dismiss the RICO claims. Plaintiffs filed a motion to remand the case to state court, which the Company has opposed. The cases were mediated unsuccessfully in December 2018 and the State Court case was originally set for trial on January 22, 2019. However, as discussed below, all of the civil cases were later stayed on December 28, 2018 and currently remain stayed. On December 6, 2018, a former Wolf Tree employee pled guilty to conspiracy to conceal, harbor, and shield illegal aliens. On December 21, 2018, the United States federal prosecutors filed a motion to stay both actions on the grounds that on December 13, 2018, an indictment was issued charging two former Wolf Tree employees and another individual with various crimes, including conspiracy to murder the deceased. Two of the three individually charged defendants have pled guilty to charges on March 28, 2022 and April 11, 2022 but have not yet been sentenced. A third individual criminally charged defendant is scheduled to go to trial in August 2022. Previously, on December 17, 2018, the United States Attorney’s Office for the Southern District of Georgia informed the Company and Wolf Tree that they are also under investigation for potential violations of immigration and other laws relating to the subject matter of the ongoing criminal investigation referenced above. The Company and Wolf Tree are cooperating with the investigation and have met with both the civil and criminal divisions of the Department of Justice ("DOJ") to resolve the matter. Due to pandemic-related issues and delays on the side of the DOJ, the matter currently remains unresolved. On December 28, 2018, the State Court granted the United States’ motion to stay but indicated that it would nonetheless consider certain pending matters, including: (1) Plaintiff and a co-defendant’s motions that Davey Tree be forced to produce privileged documents and testimony, which had been submitted to a Special Master for recommendation; and (2) the Defendants’ motions for summary judgment. On January 11, 2019, the Special Master issued his recommendation that both Plaintiff and the co-defendant’s motions to force Davey to disclose privileged information be denied. The State Court judge has not yet moved on the recommendation. On January 29, 2019, the State Court heard oral argument on Defendants’ motions for summary judgment, and the motions remain pending during the stay of the cases. On January 28, 2019, the Federal Court also granted the United States’ motion to stay. On January 29, 2019, the State Court ordered the parties to return to mediation, which occurred on April 17, 2019 but was unsuccessful in resolving the matters. All civil cases continue to remain stayed. In both cases, the Company has denied all liability and is vigorously defending the action. It also has retained separate counsel for some of the individual defendants, each of whom has denied all liability and also is vigorously defending the action. Northern California Wildfires Five lawsuits have been filed that name contractors for PG&E Corporation and its subsidiary, Pacific Gas and Electric Company (together, "PG&E"), including Davey Tree, with respect to claims arising from wildfires that occurred in Pacific Gas and Electric Company’s service territory in northern California beginning on October 8, 2017. An action was brought on August 8, 2019 in Napa County Superior Court, entitled Donna Walker, et al. v. Davey Tree Surgery Company, et al ., Case No. 19CV001194. An action was brought on October 8, 2019 in San Francisco County Superior Court, entitled Quinisha Kyree Abram, et al. v. ACRT, Inc., et. al , Case No. CGC-19-579861. Three additional actions were brought on January 28, 2021 in San Francisco County Superior Court, by fire victims represented by a trust, which was assigned contractual rights in the PG&E bankruptcy proceedings. These cases are entitled John K. Trotter, Trustee of the PG&E Fire Victim Trust v. Davey Resource Group, Inc., et al ., Case No. CGC-21-589438; John K. Trotter, Trustee of the PG&E Fire Victim Trust v. Davey Resource Group, Inc., et al ., Case No. CGC-21-589439; and John K. Trotter, Trustee of the PG&E Fire Victim Trust v. ACRT Pacific, LLC, et al ., Case No. CGC-21-589441. On September 22, 2021, the court granted Davey Tree's petition to coordinate all cases, including Walker, as a California Judicial Council Coordination Proceeding, In Re North Bay Fire Cases, JCCP No. 4955. As a result of the coordination order, all five of the individual actions are stayed in their home jurisdictions. The next case management conference in JCCP No. 4955 was held on February 24, 2022. At that case management conference, the Court ordered a mediation between the Plaintiffs and Davey Tree related to Davey Tree's contracts with PG&E. This mediation shall be scheduled by May 27, 2022, with the mediation to occur thereafter. This mediation would include Davey Tree, the Fire Victim Trust, and all other plaintiff groups. Separately, the court ordered that all parties shall participate in a global mediation, including selecting a mediator, shall begin the process of securing a mediation date by May 27, 2022, and shall complete a first session of a mediation by October 28, 2022. The Defendants have also received evidence from the Plaintiff's Trust and PG&E collected by those parties during the PG&E bankruptcy proceedings and Davey Tree's experts have begun their initial inspection of the evidence. Davey Tree has responded to all claims asserted by the Plaintiffs in these actions, denying all liability in these cases and is vigorously defending against Plaintiffs' alleged claims. In all cases, the Company denies all liability and will vigorously defend the actions.

The Davey 401KSOP and Employee Stock Ownership Plan [Abstract]
The Davey 401KSOP and Employee Stock Ownership Plan [Text Block]	The Davey 401KSOP and Employee Stock Ownership Plan On March 15, 1979, the Company consummated a plan, which transferred control of the Company to its employees. As a part of this plan, the Company initially sold 120,000 common shares (presently, 46,080,000 common shares adjusted for stock splits) to its Employee Stock Ownership Trust (“ESOT”) for $2,700. The Employee Stock Ownership Plan (“ESOP”), in conjunction with the related ESOT, provided for the grant to certain employees of certain ownership rights in, but not possession of, the common shares held by the trustee of the ESOT. Annual allocations of shares have been made to individual accounts established for the benefit of the participants. Defined Contribution and Savings Plans-- Most employees are eligible to participate in The Davey 401KSOP and ESOP Plan. Effective January 1, 1997, the plan commenced operations and retained the existing ESOP participant accounts and incorporated a deferred savings plan (a “401(k) plan”) feature. Participants in the 401(k) plan are allowed to make before-tax contributions, within Internal Revenue Service established limits, through payroll deductions. Effective January 1, 2020, we match, in either cash or our common shares, 100% of the first three percent and 50% of the next two percent of each participant's before-tax contribution, limited to the first five percent of the employee’s compensation deferred each year. All nonbargaining domestic employees who attained age 21 and completed one year of service are eligible to participate. In May 2004, we adopted the 401K Match Restoration Plan, a defined contribution plan that supplements the retirement benefits of certain employees that participate in the savings plan feature of The Davey 401KSOP and ESOP Plan, but are limited in contributions because of tax rules and regulations. Our common shares are not listed or traded on an established public trading market, and market prices are, therefore, not available. Semiannually, an independent stock valuation firm assists with the appraisal of the fair market value of our common shares based upon our performance and financial condition. The Davey 401KSOP and ESOP Plan includes a put option for shares of the Company’s common stock distributed from the plan. Shares are distributed from the Davey 401KSOP and ESOP Plan to former participants of the plan, their beneficiaries, donees or heirs (each, a “participant”). Since our common stock is not currently traded on an established securities market, if the owners of distributed shares desire to sell their shares, the Company is required to purchase the shares at fair value for two 60-day periods after distribution of the shares from the Davey 401KSOP and ESOP. The fair value of distributed shares subject to the put option totaled $570 and $1,279 as of April 2, 2022 and December 31, 2021, respectively. The fair value of the shares held in the Davey 401KSOP and ESOP totaled $173,525 and $168,652 as of April 2, 2022 and December 31, 2021, respectively. Due to the Company’s obligation under the put option, the distributed shares subject to the put option and the shares held in the Davey 401KSOP and ESOP (collectively referred to as 401KSOP and ESOP related shares) are recorded at fair value, classified as temporary equity in the mezzanine section of the consolidated balance sheets and totaled $174,095 and $169,931 as of April 2, 2022 and December 31, 2021, respectively. Changes in the fair value of the 401KSOP and ESOP Plan related shares are reflected in retained earnings while net share activity associated with 401KSOP and ESOP Plan related shares are first reflected in additional paid-in capital and then retained earnings if additional paid-in capital is insufficient.

Accounting Policies [Abstract]
Basis of financial statement preparation, policy [Policy Text Block]	The condensed consolidated financial statements present the financial position, results of operations and cash flows of The Davey Tree Expert Company and its subsidiaries. When we refer to “we,” “us,” “our,” the "Company," “Davey,” or “Davey Tree”, we mean The Davey Tree Expert Company and its subsidiaries, unless otherwise expressly stated or the context indicates otherwise. We have prepared the accompanying unaudited condensed consolidated financial statements in accordance with accounting principles generally accepted in the United States (“U.S. GAAP”), as codified in the Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”), and with the rules and regulations of the Securities and Exchange Commission (“SEC”) for interim financial information. The condensed consolidated financial statements include all adjustments which, in the opinion of management, are necessary for a fair presentation of the results for the interim periods presented. All such adjustments are of a normal, recurring nature. All intercompany accounts and transactions have been eliminated in consolidation. Certain information and disclosures required by U.S. GAAP for complete financial statements have been omitted in accordance with the rules and regulations of the SEC. We suggest that these condensed consolidated financial statements be read in conjunction with the financial statements included in our annual report on Form 10-K for the year ended December 31, 2021 (the “2021 Annual Report”).
Use of estimates, policy [Policy Text Block]	Use of Estimates in Financial Statement Preparation--The preparation of financial statements in accordance with U.S. GAAP requires the use of estimates and assumptions that affect reported amounts. Our condensed consolidated financial statements include amounts that are based on management’s best estimates and judgments. Estimates are used for, but not limited to, accounts receivable valuation, depreciable lives of fixed assets, long-lived asset valuation, self-insurance accruals, income taxes, stock valuation and revenue recognition. Actual results could differ from those estimates.
Income tax, policy [Policy Text Block]	Our income tax provision for interim periods is determined using an estimate of our annual effective tax rate adjusted for discrete items, if any, that are taken into account in the relevant period. Each quarter we update our estimate of the annual effective tax rate and, if our estimated annual tax rate changes, we make a cumulative adjustment.
Earnings per share, policy [Policy Text Block]	We calculate our basic earnings per share by dividing net income or net loss by the weighted average number of common shares outstanding during the period. Diluted earnings per share are calculated in a similar manner, but include the effect of dilutive securities. To the extent these securities are antidilutive, they are excluded from the calculation of earnings per share.
Segment reporting, policy [Policy Text Block]	We have two reportable operating segments organized by type or class of customer: Residential and Commercial, and Utility.
Commitments and Contingencies, Policy	On a quarterly basis, we assess our liabilities and contingencies in connection with outstanding legal proceedings utilizing the latest information available. Where it is probable that we will incur a loss and the amount of the loss can be reasonably estimated, we record a liability in our consolidated financial statements. These legal accruals may be increased or decreased to reflect any relevant developments on a quarterly basis. Where a loss is not probable or the amount of the loss is not estimable, we do not record a legal accrual, consistent with applicable accounting guidance.
