Question: My pear sometimes blooms in the fall. What causes that?

Answer: Pears, like several other spring-flowering trees, shrubs and vines, bloom when they come out of a prolonged dormant period. In the spring, these plants are breaking cold-weather dormancy. In the fall, they’re responding to the end of the hot, dry Texas summer. The fall bloom should, in no way, diminish their performance the following spring.
