Bigroot cranesbill: when to prune it?
Little needed. After flowering in July you can cut off the flower stems, and in March remove old, withered leaves.
Bigroot cranesbill: how to prune it?
- After flowering, cut the spent stems off just above the leaves.
- In March, remove brown and damaged leaves so the new foliage comes through nicely.
- If the mat has become bare and leggy, cut it back hard in spring: it soon regrows.
- Wear gloves if you like: the scent of the leaves lingers on your hands for a long time.
How much to cut, and how often?
- There are 2 pruning periods a year: March and July. You don’t have to prune in every one.
What does it mean for wildlife?
- Bigroot cranesbill flowers in May–July, when it attracts bees.
- If pruning falls during flowering, wait until it is over or leave part of the plant to flower, so bees and butterflies still benefit.
