Rusty foxglove: when to prune it?
After flowering, in August or September. Otherwise no pruning is needed.
Rusty foxglove: how to prune it?
- Cut the main spike back to the rosette once most flowers have faded; smaller side spikes sometimes follow.
- If you want it to self-seed, leave one or two spikes until the seed capsules turn brown and split open.
- In spring, remove dead leaves from the rosette.
How much to cut, and how often?
- One pruning period a year: August–September.
What does it mean for wildlife?
- Rusty foxglove 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.
Caution: Wear gloves when pruning and wash your hands afterwards: the sap and all parts of the plant are poisonous.
