Silver sage: when to prune it?
In April you clear away dead leaves. In June–July you cut off the flower stems if you want to keep the rosette.
Silver sage: how to prune it?
- Carefully remove dead or damaged leaves in April, by hand or with secateurs.
- Cut the flower stems down to the base at the start of flowering (June) if you want to save the rosette.
- If you want the flowers and seed, leave the stems and cut them off after flowering (July).
How much to cut, and how often?
- There are 2 pruning periods a year: April and June–July. You don’t have to prune in every one.
What does it mean for wildlife?
- Silver sage flowers in June–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.
Caution: Never prune in wet weather and do not cut the rosette itself: wounds in the woolly foliage rot quickly.
