Most perennials prefer to be transplanted, divided or dug and moved in the early spring. There are a couple of exceptions.
Iris and daylilies both can be divided and transplanted now. This is a great way to add more plants to your own yard or share some of your plants with others. Both daylilies and iris should be divided every 3-5 years. This helps increase the number of blooms that the plants will have.
Tonight, I will be out with Harley (the dog) digging up a few daylilies from the garden on the south side of the house and moving them to the back.
