Snow-in-summer: when to prune it?
Straight after flowering, in late June or in July. Otherwise there is little pruning to do.
Snow-in-summer: how to prune it?
- Shear off the spent flower stems and the top growth with shears or a hedge trimmer, just above the dense mat.
- It soon makes fresh silver-grey foliage, the carpet stays compact and it does not self-seed.
- In spring, cut out bare, woody or dead patches.
- Trim back runners that spread over paths or other plants.
How much to cut, and how often?
- One pruning period a year: June–July.
What does it mean for wildlife?
- Snow-in-summer flowers in May–June, 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: Do not prune in late autumn: the mat should go into winter with its leaves.
