Crevice alumroot (Heuchera micrantha): when to prune it?
No real pruning needed. Remove old or damaged leaves in March and cut off spent flower stems in August.
Crevice alumroot (Heuchera micrantha): how to prune it?
- In March, cut off brown, withered or frost-damaged leaves at the base.
- Leave the healthy evergreen leaves: they protect the heart of the plant.
- Cut spent flower stems off at the base to keep the plant compact.
- If the stem has become long and bare, replant deeper in spring instead of pruning.
How much to cut, and how often?
- There are 2 pruning periods a year: March and August. You don’t have to prune in every one.
What does it mean for wildlife?
- Crevice alumroot (Heuchera micrantha) flowers in June–August, 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.
