Q. How and when should I divide my spring-blooming bulbs?
A. When spring-blooming bulbs exhibit a diminished floral display and show a decreased amount of vigor, it is usually time to divide them. Dig the bulbs up with a spading fork after the leaves have dried and turned brown. Pull the clumps apart or separate them with a spade, detaching any bulblets that separate easily. Discard any bulbs that are damaged, soft, or showing signs of decay. Replant healthy individual bulbs immediately. Young bulbs will need to grow to a mature size in order to flower, which usually takes approximately one or two years.
