Normally you will want to divide perennial plant clumps that have grown to two or three times their original size within three to five years. Overgrown clumps that have exceeded the space allotted are prime candidates for division.
Disturbing the root system of a perennial interrupts the plants ability to feed and hydrate itself. If you saturate the plant with water first, it reduces the trauma during division.
While digging up the entire plant ball and cutting with a shovel or knife works effectively to divide a plant, I find it just as easy to do it while the plant is in the ground.
Carefully place your shovel or spade on the plant exactly where you want to divide it. Using your foot, force your shovel down into the ground, slicing the plant in half. Pull the division out and replant it as soon as possible. It’s that easy!
Now it is time to have fun—call up a friend and ask if they would like a few plants. They will love getting them for free, and it is a great way to encourage beautification of your neighborhood.
