DIVIDE PERENNIALS: Early and mid-spring is a good time to divide most perennials, depending in the zone you live. You will know is time to divide when you get to see that your plant is growing; however, is dead or empty in the center.
A good rule of thumb is to divide perennials after they flower, therefore, you can divide the fall bloomers now, in spring.
Do not divide the peonies or irises now, just wait until fall and do it then.
Google the name of the plants that are showing the empty centers in your garden and get the information on how to divide them and exactly when.
Once you divide your perennials, make sure that you share some of the divided excess with family, neighbors and friends. Don't forget to use some of them to plant elsewhere in your garden.
