Fertilize your spring flowering bulbs with a slower-releasing granular of one to two pounds of 10-10-10 per 100 square feet when shoots first appear in spring and ideally four to six weeks before bloom. Adding fertilizer in spring produces healthy and robust foliage which consequently allows bulb’s to increase stored carbohydrates that will produce a larger bloom the next year. Work in granular fertilizer shallowly around the bulbs. Repeat this application in the early fall when newly growing roots start spreading.
