Licence verification
Is a plant nursery licensed in Maryland? How to check
Does Maryland publish a public registry?
Yes. The Maryland Department of Agriculture, Plant Protection & Weed Management maintains a public register of licensed nursery dealers and growers. View the registry .
What we hold
- Records on file
- 1,233
- As of
- 2026-07-13
Fields captured: licence number, business name, address, county, phone, source URL, and this as-of date, for every record.
A "State-licensed" badge only asserts current licensure while its registry file is 90 days old or less; past that, the badge on an affected listing states its as-of date instead of claiming current status. 1,231 of the 1,233 records on file here are older than that cap: those listings currently show the unconfirmed, as-of-date form of the badge, not "State-licensed."
We do not claim every nursery listed on this site in Maryland is licensed. Only the 1,233 businesses matched against this exact registry carry a "State-licensed" badge on their own listing page, each linking back to this registry as its citation.
Licensed by regulatory role

How to verify a specific business
Search our Maryland directory for the business by name. A "State-licensed" badge on its listing page means we matched it against this exact registry, with the date we checked. If it isn't in our directory yet, check the state's own list directly.
Format
An annual dated PDF directory, ordered by county then firm name.
The Maryland Department of Agriculture's Plant Protection & Weed Management program publishes an annual Nursery Directory, a county-by-county PDF listing every licensed nursery firm in the state.
We matched the Maryland businesses shown above against that directory. Most of those matches carry the directory's own printed date, August 8, 2025, now well past the 90-day cap described above, so nearly all of them show the plain as-of-date form rather than "State-licensed." A smaller number were matched or re-checked more recently and carry a fresher date instead. A Maryland business with no badge at all may hold a real, current license we simply have not matched against this file yet.
The department's own Nursery Directory above is the record to check or correct first. This directory's own correction link, on any listing page, lets you flag a wrong or outdated match, and we will re-check it against the next directory Maryland publishes.
Other states we hold a registry for
Only these 11 states publish (or make bulk-extractable) a public licensed-nursery registry we've verified directly. Every other state is silent here on purpose, not overlooked.
