The Guide: Landscaping & Lawn Care in Watchung Hills, NJ
How to Use This Guide
This guide lists the landscaping and lawn care businesses that work in Watchung Hills, NJ, with where each is based, what its own website says it sells, and what the New Jersey Home Improvement Contractor register shows for it. Hardscaping and outdoor living businesses are in a separate guide: Hardscaping & Outdoor Living in Watchung Hills, NJ.
The Type column shows what each business’s own website says it sells: Maintenance for recurring lawn and grounds care, Design & installation for planting and installation work, and Both where the website offers both. In Based in, Local means the business is based in these towns, Very Close means in a bordering town, Somerset County means elsewhere in the county, and Regional means outside it.
This guide covers Warren, Watchung and Green Brook. A business is listed when it has its own website or Google Business Profile, does the work with its own crews, says it works in these towns or the county, and is not a national franchise or lead marketplace. Businesses are listed alphabetically.
About This Guide
This guide is produced by Garden State Circle. Landscaping and lawn care businesses appear here because they meet the criteria described above — a website or Google Business Profile of their own, crews that do the work themselves, work in these towns or the county, and independence from a national franchise or lead marketplace. That is a test, not a judgment, and it is the only route onto this page. No business can pay to be included in this guide, to be listed higher, or to change what the table says about it. Businesses are listed alphabetically, and every detail in the table was verified against each business’s own website or Google Business Profile, and its registration against the New Jersey Division of Consumer Affairs, in October 2026.
Everything under the heading that begins this guide is governed by the rules above, on every guide we publish. Garden State Circle is supported by the businesses that participate in it. Participation pays for our ongoing work: keeping a business’s entry accurate, re-checking its record, and publishing a page of its own details that the business maintains. There is no paid placement in this guide. Participation does not buy a place here, a position here, or anything the comparison table says. Where a row carries a verification date, that is when we last checked that business’s record ourselves. A row without one has not been checked recently — that is a fact about our work, not about the business.
Garden State Circle is published in New Jersey by Tiffany and Jake Slowinski and covers Warren, Watchung and Green Brook. Contact the publisher at jake@gardenstatecircle.com. How every guide is made, in one place: how every guide is made.

Towns, types, certifications and services are each business’s own, taken from its own website or Google Business Profile in October 2026. Registration numbers, registered names, statuses and towns were read on the New Jersey Division of Consumer Affairs register in October 2026. Not found by us under this name means we did not find a registration under the name the business uses; it does not say the business has none. Not required for maintenance-only work is printed where the business’s own website sells maintenance only. Certifications are each business’s own statement on its own website, and we have not confirmed them with the issuing body. Not published means the source we read does not say.
Common Questions
Does a landscaper need a license in New Jersey?
No. New Jersey does not license landscapers. A business that does home improvement work for homeowners is required to register as a Home Improvement Contractor with the Division of Consumer Affairs, and the table prints the registration where we found one. Pesticide and fertilizer applicator credentials are held by individual people rather than by a business, and the table prints them only as a business states them on its own website.
How do I check a registration myself?
Use the NJ Home Improvement Contractor registration lookup under Additional Resources, search the business name, and compare the registered name and status with the table.
What does the Type column mean?
It is what the business’s own website says it sells. Maintenance means recurring lawn and grounds care. Design & installation means planting design and installation work. Both means the website offers both.
What does “Not found by us under this name” mean?
We searched the register under the name the business uses and did not find a matching registration. It does not say the business has none; it may be registered under a different legal name.
When was this list last checked?
The Record checked column shows the month we last read each row. If something here is wrong or has changed, write to admin@gardenstatecircle.com.

Something out of date?
This guide is maintained. If anything here is wrong or has changed — a name, an address, a registration number, or whether a business has closed — tell us and we will check it. Businesses listed here are welcome to write in directly.
And if you run a landscaping or lawn care business that should be on this list and is not: the test is the same one every business here cleared — that you work in Warren, Watchung and Green Brook, that you publish that work as a service on your own website or Google Business Profile, and that you do it with your own crews. Show us that and you go on the page.
