How to divide perennial plants

1 Lift the plant with a spade, digging widely around the roots and keeping as much soil attached as possible. 2 Using a sharp spade or knife, slice the plant into three or four sections. Make sure each piece has healthy roots and shoots. 3 Replant the divisions at the same depth as their roots, firming them in. If there is a delay, wrap the roots in damp newspaper for up to 48 hours. 4 Water the plant well and mulch generously. Don’t let it dry out as it gets established, protect it from pests and weed around it regularly.
