Can anyone help me out here. I am unsure if i need to obtain this certificate. I only but small amounts of plants, mainly annuals and the occasional installation. I can't figure out what the wording is trying to say. This info come from the NYS OPAL site. Nursery dealer means any person, firm, partnership, association or corporation, NOT A GROWER OR AN ORIGINAL PRODUCER OF NURSERY STOCK, in New York which or who buys, acquires, or receives on consignment nursery stock for the purpose of reselling, transporting, or otherwise disposing of the same. The certificate registers nursery dealers as selling only certified stock and is required as a condition of sale. Persons desiring to sell, or handle for sale, or otherwise dispose of nursery stock in New York must register unless they are registered as or plan to register as a Plant Grower. Does anybody from NY know if this is necessary for a landscaper.
