I would like to know when to fertilize my daffodil and tulip bulbs? Is it in the spring before the bulbs bloom, after they bloom or in the fall?

Hi - Our recommendation is to fertilize spring-flowering bulbs immediately after they bloom using a 5-10-10 fertilizer. After blooming, the plants will put their energy into bulb development and storing nutrients to support their growth and flowering for next year. You could also fertilize the planting area in the fall, but it is really right after flowering when the plants can most use the boost of nutrients.
