Avoiding and Solving Common Bulb Problems (page 2 of 2)
by National Gardening Association Editors
If bulbs have become crowded and are competing, dig and divide them. Reduce competition from surrounding plants by weeding and mowing regularly.
To increase soil fertility, in spring when plants are growing, spread an inch of compost or feed with a low-nitrogen bulb fertilizer according to package directions.
If shade has increased, thin tree branches or surrounding plants to allow at least half a day of sun in spring while the bulb leaves are green (in warmest climates, afternoon shade is recommended).
