PASS ALONG YOUR PERENNIALS
Posted on Jul 24, 2013


When to divide perennials depends on the type of plant and how quickly it's growing. Keep an eye out for clumps that have grown 2-3 times their size within 2-5 years. Any overgrown clump or any clump that has simply exceeded the space allotted is a candidate for division.
 
Spring is usually the best time for division. Since the plants are actively growing, their leaves are not so developed that the root system can't take a little disturbance and still feed the top of the plant. However, just as different plants can go different lengths of time before being divided, some plants, like peonies, prefer to be divided in the early fall.
 
Among perennials that benefit from division:
Irises
Liriope
Day lilies
Hostas
Peonies
Shasta daisies
Ornamental grasses
Mums
Thyme
Phlox
Purple cone flower
Blanket flower
Black-eyed Susans
