How to Divide Perennials
This guide shows you how to split overcrowded perennials in autumn and turn one plant into several, completely free. You'll learn how to spot a clump that's ready, lift it without doing too much damage and get the divisions back in the ground before winter sets in. The hands-on work takes half an hour or so per clump. After that, it's just watering and patience while the new plants settle in.

Dan's Tip
Don't be gentle out of guilt. Perennials are tougher than they look, and a firm hand with a fork or spade does far less damage than half-heartedly pulling a clump apart.
Step by step guide
Check the Clump
Look for a perennial that has become congested, with a dead or weak centre and most of the healthy growth around the edges. This is the clearest sign it's ready to be divided and will benefit from being split up.
Water the Day Before
Give the plant a good water the day before you plan to divide it, especially if the soil is dry. Moist soil is easier to work with and causes less stress to the roots during lifting.
