A person may not sell nursery stock without a license issued by the commissioner. Licenses expire on December thirty-first each year unless revoked at an earlier date. An application for renewal of license with any additional information required by the commissioner must be submitted and accompanied by a fee of fifty dollars on or before December thirty-first each year. A separate license is required for each place of business. A fee of ten dollars must be submitted for each additional license, other than the principal place of business. A license may not be issued to a grower unless the grower has first been issued a certificate of inspection.
