Starting a landscaping business in New Hampshire is like planting a garden; you need the right groundwork to flourish.
From registering your business to determining if you need to apply pesticides, there are a few official steps to ensure your venture is both compliant and above board.
Whether you’re trimming shrubs or managing entire estates, understanding licensing requirements, such as those for Plant Dealers/Landscapers and pesticides, helps you build trust, stay compliant, and let your green thumb truly shine.
Licensing Requirements for a Landscaping Business in New Hampshire
a. Plant Dealer & Landscaper License
If you’re handling nursery stock buying, selling, or storing plants, you may need a Plant Dealer/Landscaper License from the New Hampshire Department of Agriculture, Markets & Food (NH DAMF).
Specifically:
- If you hold nursery stock, even temporarily, you must obtain this license. It’s valid annually, running from January 1 to December 31. Cost of the license? A modest $25 per year.
- Some exemptions apply: For example, if your total gross sales of rooted plant material are under $3,000, or you don’t store or import out-of-state nursery stock, you might not need the license.
- The application is via the “Plant Dealer / Landscaper Application” form, and once approved, you’re expected to post the license at each location.

For more information regarding the license, visit the official website of New Hampshire Department of Agriculture Markets and Food.

You can also visit the New Hampshire Legal Information, Cornell Law School, for getting legal information.
This license ensures that anyone you source nursery stock from is also certified or licensed, making the entire supply chain accountable and healthy.
b. Pesticide Applicator Licensing
If your landscaping work involves managing pests, such as spraying herbicide or managing invasive plants, you’ll need to look into pesticide applicator licenses:
Private Applicator Permit: If you’re applying pesticides on your own property or someone else’s property in exchange for non-cash exchanges, you might need this. Some general-use products require only an annual report, while restricted-use products require an exam, training, and reporting.
Commercial Applicator License (for hire): If you’re applying pesticides on others’ properties for compensation, this includes lawns, gardens, or even public spaces, you definitely need a Commercial Applicator License.
Pesticide Dealer License: If you plan to sell, distribute, or even hold restricted-use pesticides, you must be licensed as a dealer.
Renewals and Continuing Education
Commercial Applicators licenses must be renewed every 5 years and complete 12 continuing education credits per category licensed.
Private Applicators require 15 credits over 5 years and renewal every 5 years.

These requirements make sure landscapers aren’t just green-thumbed but also pesticide-savvy, especially when it comes to safety and the environment.
c. Certification: NHLA Certified Landscape Professional (NHCLP)
While not a government license, the NHLA Certified Landscape Professional (NHCLP) is a respected certification from the New Hampshire Landscape Association. It’s optional, but highly valuable for credibility.
To earn NHCLP, you need to keep in mind certain guidelines:
- You need to have documented experience: either 2,100 hours in the landscaping industry, or 1,400 hours+one year of post-secondary horticultural education.
- Pass an exam (written and plant ID exam, which are offered in March and September) and pay a fee of —$120 (for members), $150 for non-members.
- A certification manual (on USB) is included with the exam fee or available separately for $30.

You can visit the official website of NHLA to know more about NHCLP Application for Examination.
This badge not only boosts professionalism but opens networking doors, adds credibility to bids, and helps you stand out.
d. Business Registration & Local Permits
New Hampshire doesn’t require a general state-level business license for most tasks.
However, here are few things to keep in mind:
- You should register your business structure (LLC, sole proprietorship, etc.) with the New Hampshire Secretary of State, especially before applying for other licenses.
- Your local city or town may require permits or registration, such as zoning clearance or a general business permit. It’s always a good idea to check your town clerk’s office.
- Finally, don’t forget insurance—public liability, property damage, bodily injury coverage, and possibly workers’ compensation if you employ help, to protect both you and your clients.
