Clustered bellflower: how to prune it?

1. Cut faded flower stems back to just above the leaves at the base.
2. Then water and add some compost: a smaller repeat flush often follows in late summer.
3. In between, cut off faded clusters if you do not want seedlings.
4. In March, cut last year’s dead stems and leaves down to the ground.

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?

• Clustered bellflower 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.
• As a native plant, it feeds more insects than a non-native species.
