Crowded bulbs, or those producing fewer or smaller blooms than normal probably need to be divided. Do not dig the bulbs until after the foliage has yellowed. Diseased or wormy bulbs should be thrown out. Very small bulbs may not bloom for one or two years so. After digging, bulbs that can’t be planted immediately are stored in a cool, dry, dark area at temperatures between 50 and 70 degrees. A few bulbs can be put in paper bags and hung from the ceiling. Large numbers of bulbs can be put, no more than 3 deep, on trays with screen bottoms. Inspect bulbs for rot during the storage period. The bulbs are replanted in October. Before digging and dividing, check the cultural information given for specific plants.
