I am curious to know why after blooming profusely for the last several years, this year, the bulbs shot up the greenery but no blooms came. Can you give me an answer? Thank you. Ron Dixon

There are three possible reasons for non-blooming daffodils. 1) If bulbs are overcrowded, competition for moisture and nutrients could affect bloom. If you've allowed your bulbs to naturalize, it may be time to dig and divide them. 2) Daffodils have a winter chill requirement for best growth and flower display. If your winter weather was mild, they may not have gotten the signal that it's time to bloom. This is only a temporary setback and the bulbs should bloom on schedule next year. 3) While it's okay to cut back spent flowers and stems, it's important to leave the foliage alone until it withers away naturally. Foliage transports energy to the bulb for the following year's bloom. If you cut back the foliage while it was still green last year, you compromised the bulb's ability to produce a flower. Hope at least one of these possibilities fits the situation and answers your question!
