How to Start a Landscaping Business in Delaware (Step by Step)

Step 1: Register Your Business and Get Your Delaware Business License

Form an LLC with the Division of Corporations ($90) at icis.corp.delaware.gov/ecorp and obtain your Delaware Business License ($75/year) from the Division of Revenue at onestop.delaware.gov. The Business License is required for all Delaware businesses regardless of industry. If operating under a trade name, register it for $25 at the same portal.

After forming your LLC, pay the $300 annual franchise tax by June 1 each year at corp.delaware.gov/paytaxes.

Step 2: Determine Your Services (Pesticide Work?)

Delaware divides landscaping requirements based on whether you apply pesticides:

• General landscaping only (mowing, planting, mulching, pruning, grading, irrigation installation): No specialized state license required beyond the Delaware Business License.
• Pesticide application (weed control, pest control, lawn chemical treatments, tree/shrub spraying): Requires Commercial Applicator Certification and a Pesticide Business License.
• Fertilizer application on client property (more than 1/4 acre commercially): Requires Commercial Nutrient Management Certification (effective May 2025).

Step 3: Obtain Commercial Pesticide Applicator Certification (If Applying Pesticides)

If you will apply pesticides on clients’ property for compensation, you must become a certified Commercial Applicator through the Delaware Department of Agriculture, Pesticide Management Section.

• Relevant Category: Category 03 – Ornamental and Turf Pest Control (maintenance of ornamental trees, shrubs, flowers, and turf)
• Certification fee: $50 (initial and renewal)
• Category exam fee: $25 per category
• Renewal: Every 3 years. Requires 12 Continuing Education Units (CEUs) – 8 must be specific to Category 03.

Apply and register for the exam through the online portal: dda.my.site.com/pesticide. For questions: Delaware Department of Agriculture, Pesticide Management Section, (302) 698-4571. Website: agriculture.delaware.gov/pesticide-management.

You may also hire a Pesticide Technician to apply pesticides under your supervision. Technicians must register with the Department ($25 fee) but do not need to pass the certification exam – they must work under a certified applicator’s direct supervision.

Step 4: Obtain a Pesticide Business License (If Running a Pesticide Business)

If your landscaping company commercially applies pesticides (not just you personally, but as a business offering pest/weed control services), you need a Pesticide Business License from the Delaware Department of Agriculture.

• Annual fee: $100
• Renewal deadline: December 31 each year. Late renewal after January 1 incurs a 20% penalty.
• Requirements: At least one Certified Commercial Applicator in the category of work you perform must be associated with the business.
• Insurance required: Minimum $300,000 bodily injury/death per occurrence and $100,000 property damage per occurrence.
• Vehicle marking: All service vehicles must display the business name and Pesticide Business License number in letters 2-6 inches tall.
• Apply at: agriculture.delaware.gov/pesticide-management/business-licenses

Step 5: Commercial Nutrient Management Certification (If Applying Fertilizers)

Effective May 2025, Delaware requires a Commercial Nutrient Management Certification if you apply nutrients (including fertilizers) to more than one-quarter acre as part of a commercial landscaping business.

• Fee: $100 per year
• Exam required
• Administered by: Delaware Department of Agriculture, Nutrient Management Program
• Website: agriculture.delaware.gov/nutrient-management

Step 6: Get Business Insurance

Essential insurance for a Delaware landscaping business:

• General liability insurance: Minimum $1 million per occurrence recommended. Required at $300,000 min for Pesticide Business License.
• Commercial auto insurance: Required for business vehicles – personal auto policies do not cover commercial use.
• Workers’ compensation: Required as soon as you hire one employee. Delaware has no minimum headcount threshold.
• Equipment insurance: Covers mowers, trimmers, and other equipment from theft and damage.

Step 7: Register for Gross Receipts Tax

Register with the Division of Revenue for the Gross Receipts Tax (GRT) at grossreceiptstax.delaware.gov. For landscaping and service businesses, the GRT rate is 0.3983% on revenues above the monthly exclusion ($100,000/month for most service businesses). Most small landscaping businesses starting out owe $0 in GRT. Delaware has no sales tax – you do not collect sales tax from clients. Phone: (302) 577-8780.
