WINTER STORAGE OF TENDER BULBS
WINTER STORAGE OF TENDER BULBS
In storing tender bulbs through the winter, it is important to keep several things in mind. Store only disease-free, healthy, sound bulbs. Many gardeners use small trays and cover the bottoms with screen for storing small bulbs, corms, and tubers.
Perforated plastic bags might possibly be used to store bulbs that have a tendency to shrivel. The relative humidity in the storage area should be about 50%. Check all bulbs MONTHLY for dehydration, excess moisture, diseases, and sprouting.
