Container-Grown Floriculture Plants and Nursery Stock (Does not apply to
seedlings: see specific instructions for seedlings).
- Two to four entire plants should be sent. They should be left in the containers or carefully
removed from pots and transferred to plastic bags.
- Each plant should be placed in a plastic bag large enough to cover entire plant. The root
system and soil should be tied off to keep soil off leaves, then the rest of bag should be brought
up over the top and tied again.
- The sample should be mailed in a cardboard box with protective padding material such as
old newspapers around plants to keep them from moving around in the box while in transit.
Small floriculture plants, such as African violets, may be sent in a large, padded envelope rather
than in a box.
Woody Ornamental Nursery Stock
- Only one or two whole plants are required, but four to six additional root samples should
be taken from other plants. Each root sample should be mixed with a cup of soil in individual
plastic bags. In this way, several representative plants can be assayed.
- For root rot without the disadvantages of sending large numbers of whole plants, the
samples should be packaged and mailed as described in items 2 and 3 above.
