Here is the latest information, effective March 23, 2020, on the status of landscape/nursery businesses under the current Executive order 2026:

Nassau and Suffolk counties have announced that landscapers in New York state may perform essential services for property maintenance and safety
, including care and maintenance of lawns and plants including plowing, mowing and plant care, but may not perform new installations. This is information that we have not yet had confirmed at the state level, but it has been shared publicly by these county governments. It applies statewide, not just to Nassau and Suffolk counties.

Garden centers, nurseries and greenhouses that grow food crops, including fruit trees, fruiting shrubs, vegetable starts or herbs are considered essential business under the farm and agriculture category and may bring in employees to maintain these plants while remaining closed to the public. This has been confirmed in discussions with the NYS Department of Agriculture.

If your business still does not have clearance to conduct business under these terms and believe that you should be classified as an “essential” business, we recommend that you apply directly for a waiver through this link to Empire State Development.  We are hearing of multiple successful applications.

We continue to work toward receiving clarification and direction on this matter directly from the state and will update you as more information becomes available.
