Rule 21-46.12 - Nursery stock viability qualifications

All nursery stock offered for sale or distribution, not meeting the following minimum indices of viability, shall be removed from public view and not offered for sale.

(1) Woody stemmed deciduous stock shall have moist, green, cambium tissue in the stems and branches and shall have viable buds or normal, green, imwilted growth. Etiolated growth from individual buds shall be no more than four inches. In the case of rose bushes, each stem must show moist, green, undamaged cambium in at least the first six inches above the graft. Any single stem on a rose bush not meeting this specification shall disqualify the entire plant; however, a bush may be pruned to remove dead or damaged canes and the plant can then be sold at the proper grade according to Standards of the American Association of Nurserymen.

(2) Balled and burlapped stock in addition to 46.12(1) above regarding aerial parts, shall have unbroken earth balls of a size specified by the American Association of Nurserymen's American Standard for Nursery Stock.

(3) Colored waxes or other materials used to coat the aerial parts of plants that change the appearance of the plant surface so as to prevent adequate inspection, are prohibited.
