How to Start a Landscaping Business in New Hampshire (2026)

Last updated: May 4, 2026

Starting a landscaping business in New Hampshire does not require a general landscape contractor license. However, the commercial pesticide applicator license from the NH Department of Agriculture, Markets and Food (DAMF) catches most full-service landscapers — because applying any pesticide, herbicide, or certain fertilizers commercially requires it. The license requires passing a Core exam and at least one Category exam (G1 for ornamental/shade trees, G2 for turf) through DAMF, with UNH Cooperative Extension offering a prep course. License fee: $60 for a 5-year term. The other critical legal requirement: call 811 (Dig Safe) at least 72 hours before any excavation, excluding weekends and holidays — even shallow landscape work triggers this requirement under RSA 374:47-56.

New Hampshire’s landscaping market is shaped by extreme seasonality and distinct regional demand patterns. The core season runs May through October, with snow removal extending operations through April in most markets. The MA/VT/ME border dynamics that define southern NH’s economy create significant landscape demand from the newly-relocated Massachusetts families who have purchased NH homes but expect the same landscaping services they had in the suburbs of Boston. The resort economy (Lakes Region, White Mountains, Seacoast) generates dense vacation property landscaping demand with a specific seasonal pattern tied to summer rental occupancy.

How to Start a Landscaping Business in New Hampshire (Step by Step)

Step 1: Determine If You Need a Pesticide Applicator License

NH’s pesticide license requirement applies based on what you apply, not what you call yourself or how you price your services:

• License required: Applying any pesticide, herbicide, fungicide, insecticide, or rodenticide that is labeled for commercial application — including lawn treatment products, weed killers, grub treatments, tree and shrub sprays, and ant/pest control products applied to landscape areas
• License not required: Pure mowing, pruning without chemical application, hardscape installation (patios, walkways, retaining walls), mulching, landscape planting, and other non-chemical services
• Gray area — fertilizer: Some fertilizer products trigger the pesticide license requirement; others do not. Contact the NH DAMF Division of Pesticide Control at (603) 271-3694 to confirm whether specific products you plan to use require the license

Step 2: Complete UNH Extension Core and Category Training

The UNH Cooperative Extension Pesticide Safety Education Program offers the recommended preparation for the NH state pesticide exams. Their training is the most widely used path to passing the state exams:

• Format: Two half-days of instruction, typically followed by a third day of state exams
• Cost: Approximately $60 per person for both instructional days
• Core course: NH pesticide laws, environmental protection, pesticide safety, application equipment, and environmental fate of pesticides
• Category G1: Shade and Ornamental Pest Control — pesticide applications on ornamental flowers, shrubs, and shade trees
• Category G2: Turf Pest Control — lawn and turf pest management including grubs, weeds, and fungal diseases
• Contact UNH Extension Pesticide Safety Education: (603) 351-3831
• Website: extension.unh.edu — Pesticide Safety Education

Taking the training course before the state exam significantly improves pass rates. Exam study materials are available through UNH Extension.

Step 3: Pass the NH Commercial Pesticide Applicator Exams

The written exams are administered by the NH DAMF Division of Pesticide Control:

• Exam fee: $15 per exam (Core exam + each Category exam = $30 minimum for one category, $45 for two)
• Schedule by calling: (603) 271-3694
• Pass both the Core exam and at least one Category exam relevant to your services
• Category G1: Ornamental, shade trees, and shrubs
• Category G2: Turf and lawn pest management
• Full-service landscapers providing both turf treatments and tree/shrub work should take both G1 and G2

Step 4: Apply for Your Commercial Pesticide Applicator License

After passing your exams, apply to the NH DAMF Division of Pesticide Control for your commercial license:

• License fee: $60
• License term: 5 years — renewal required before expiration
• Maintain required liability insurance throughout the license period as a condition of licensure
• Info: agriculture.nh.gov/farms-businesses/pesticides/pesticide-licensing
• Forms and applications: agriculture.nh.gov/publications-forms/pesticide-control.htm

Step 5: Form Your Business Entity

Register an LLC with the NH Secretary of State at quickstart.sos.nh.gov. Formation fee: $100-$102. Annual report: $100, due April 1. Landscaping businesses carry genuine liability exposure: property damage from equipment (broken windows, damaged plants, hardscape errors), pesticide drift onto neighboring properties, slip-and-falls, and equipment accidents. An LLC is essential.

Step 6: Understand NH Dig Safe Requirements

New Hampshire law (RSA 374:47-56) requires anyone planning excavation to notify the Dig Safe System before digging. This requirement affects landscaping businesses regularly:

When You Must Call 811

• Installing irrigation systems (any underground pipe)
• Planting trees or large shrubs that require deep hole digging
• Grading or regrading (any earthwork)
• Installing landscape lighting with underground wiring
• Building retaining walls requiring footings
• Removing stumps by grinding below grade
• Any excavation, grading, or underground installation work

The 72-Hour Rule

Call 811 or submit online at digsafe.com at least 72 hours before excavating — excluding weekends and holidays. This is effectively 3 business days’ notice. After you call, member utilities have up to 72 hours (excluding weekends and holidays) to mark their underground facilities with paint or flags. Your Dig Safe ticket is valid for 12 business days from the marked date. If you won’t complete all excavation within 12 business days, you must submit a new ticket.

Consequences of Not Calling

Failing to call 811 before excavating is a violation of RSA 374. More practically: if you hit an unmarked utility line — electric, gas, water, telecom — you are liable for repair costs and any damage caused by an outage. NH gas and electric utilities can cost thousands to repair. Always call 811, even for shallow work — some utilities are buried surprisingly close to the surface.

Step 7: Register for NH Taxes and Employment

New Hampshire’s tax environment benefits landscaping businesses meaningfully:

• No sales tax on landscaping labor: Mowing, pruning, planting, pesticide application, and other landscaping services are not subject to NH sales tax. You do not charge customers sales tax on labor.
• Materials: Landscaping materials (plants, mulch, fertilizer, pesticides) are treated as taxable to the contractor at purchase — you pay the tax at the supplier when you buy materials for a job. This is the same structure as most other states but operates without the complexity of charging customers sales tax.
• BPT: If gross income exceeds $109,000, file the Business Profits Tax at 7.5%. Register at revenue.nh.gov.
• UI and workers comp: Register with NHES before your first hire (new employer rate: 2.7% on first $14,000/employee). Workers comp is required at the first employee (NCCI Class 0042 for landscape gardening). NH approved a 6.1% workers comp rate cut for 2026.

New Hampshire Landscaping Market: Seasonal Patterns and Regional Demand

New Hampshire’s landscaping season runs approximately May through November for most services, with a snow removal extension through April that can be highly lucrative in heavy-snowfall years. The market is dominated by residential work in the southern tier, but with important regional variations:

The southern NH residential market (Hillsborough and Rockingham Counties) benefits directly from MA-border migration. Massachusetts families who move to NH for lower housing costs and no income tax often arrive expecting the same landscaping services they had in suburban Boston — weekly maintenance, spring/fall cleanups, fertilization programs, and hardscape work. The NH market is less saturated than eastern Massachusetts for this service tier, creating opportunity for businesses willing to build routes in growing communities like Bedford, Goffstown, Londonderry, Derry, and Windham.

The vacation property market (Lakes Region, White Mountains, Seacoast) creates intensive seasonal demand. Vacation homeowners often want the property maintained while they are not there — weekly mowing from May through October — and want a ready-to-use property when they arrive. This translates into reliable recurring revenue for landscape businesses willing to operate in resort areas. The challenge: getting paid by absentee property owners and managing the end-of-season transition.

The commercial market (HOAs, condominium complexes, office parks, retail centers) provides year-round revenue stability through multi-year maintenance contracts. HOA-served communities are dense in the Nashua, Manchester, and Seacoast corridors. Commercial landscape contracts — even small ones — tend to have longer terms and more predictable payment than residential.

Frequently Asked Questions

Do landscapers need a license in New Hampshire?

There is no general landscaping contractor license in New Hampshire. However, if you apply any pesticide, herbicide, or fungicide commercially — including lawn treatments, grub control, and tree/shrub sprays — you need a commercial pesticide applicator license from the NH DAMF Division of Pesticide Control ($60 license, $15 per exam). Pure mowing, pruning, planting, mulching, and hardscape installation without chemical applications does not require this license. Contact DAMF at (603) 271-3694 with questions about specific products.

What pesticide exam categories should landscapers take in New Hampshire?

For landscaping, the primary exam categories are G1 (Shade and Ornamental Pest Control) — for treating ornamental flowers, shrubs, and shade trees — and G2 (Turf Pest Control) — for lawn and turf pest management. You must also pass the Core exam before any Category exam. Most full-service landscapers providing both turf treatments and tree/shrub programs should take both G1 and G2. Exam fee: $15 per exam; UNH Extension offers prep courses for approximately $60/person. Contact DAMF at (603) 271-3694 to schedule.

What is the NH Dig Safe requirement and how does it affect landscapers?

RSA 374:47-56 requires anyone planning excavation to call 811 (Dig Safe) at least 72 hours before digging — excluding weekends and holidays (effectively 3 business days). This applies to any underground work: irrigation systems, landscape lighting wiring, deep planting holes, grading, retaining wall footings, and stump grinding below grade. After calling, utilities have 72 business hours to mark their lines. Your ticket is valid for 12 business days. Call digsafe.com or dial 811 — the service is free. Failure to call creates liability for utility damage.

Does New Hampshire charge sales tax on landscaping services?

No. New Hampshire has no general sales tax. Landscaping labor is not subject to state tax. Materials (plants, mulch, fertilizer, pesticides) are treated as taxable to the contractor at the point of purchase from the supplier — you pay tax when you buy materials, not when you charge your customer. This is consistent with how most other states treat contractor-furnished materials under lump-sum contracts. There is no sales tax compliance burden for your landscaping invoices.

Does New Hampshire require landscapers to carry insurance?

Commercial pesticide applicator license holders must maintain liability insurance as a condition of licensure. Beyond that requirement, NH has no separate general landscaping insurance mandate. However, general liability insurance ($1M minimum) is strongly recommended: landscaping creates real property damage and injury risks (damaged plants, broken windows, pesticide drift onto neighboring properties). Many HOA, condominium, and commercial clients require $1M-$2M minimum GL with certificate of insurance before awarding contracts. Workers compensation is required under NH RSA 281-A:5 for any employer with any employees.

How long is the NH commercial pesticide applicator license valid?

The NH commercial pesticide applicator license is valid for 5 years. License fee: $60 initial and $60 renewal. Renewal requires a renewal application and evidence of current liability insurance. Contact the NH DAMF Division of Pesticide Control at (603) 271-3694 well before your expiration date to avoid a lapse in licensure, which would require retaking exams before operating again.
