Gaura: when to prune it?
In April, when the new leaves appear at the base. Optionally a light trim in July.
Gaura: how to prune it?
- Leave the old stems standing all winter: they protect the crown from frost and wet.
- In April, cut them back to just above the new leaves at the base.
- If the plant falls open or flops in July, cut the stems back by a third: it flowers again a few weeks later.
How much to cut, and how often?
- There are 2 pruning periods a year: April and July. You don’t have to prune in every one.
What does it mean for wildlife?
- Gaura flowers in June–October, when it attracts bees and butterflies.
- 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: Don’t cut back in autumn: the crown is left open and wet, and it survives winter less well.
