Iowa Code r. 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, unwilted 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.
