Question: I want to plant wildflowers. When do I sow the seed?
Answer: You need to follow nature’s lead, at least in general. That means that spring-flowering types that would have been wild-sown in nature as the seeds matured in early summer, should at least be planted by late August or September. They germinate with the first fall rains, establishing their deep roots over late fall and winter, for the early spring bloom. Planting after mid-October is probably a waste of the seeds. Summer- and fall-flowering types, by comparison, can be planted in the spring.
