Daylillies

I have some daylilies growing in a container. What's the best time to transplant them into my garden?

Melinda: You can transplant daylilies whenever you have the time. Just follow two simple rules. First, avoid the hottest part of summer to minimize transplant shock. Second, gardeners living in colder climates should move plants by late summer so the transplants can reestablish roots before winter. In general, it's best to transplant spring-blooming perennials in late summer or early autumn, and fall bloomers in spring. Summer bloomers can be moved in spring or fall.
