Here’s our guide about dividing perennials.

WHEN ARE PERENNIALS DIVIDED?

Autumn is the ideal time to divide perennials that flower in the spring. If you are splitting a summer blooming plant, divide in early spring. Generally, plants should be divided every three to five years. Avoid dividing plants while they are still in bloom.

WHAT YOU NEED

Two garden forks, or a sharp knife
Gardening gloves
Parkwood 3-in-1 soil
Watering can

GET DIGGING

Dig up the entire plant, roots included. Lift the plant carefully from the hole and shake off excess soil. Remove any dead stems and foliage.

Separate the root system in half down the middle, using two garden forks or sharp knife.

Replant in a new hole with fresh soil and water well.
