Spotted Joe Pye weed: when to prune it?
Leave the stems standing all winter and cut them back in March. For a shorter plant, cut the stems back by a third in late May.
Spotted Joe Pye weed: how to prune it?
- In March, cut all the old stems down to about 10 cm above the ground.
- In late May you can shorten the stems by a third: the plant stays shorter and sturdier and flowers slightly later.
- You can also shorten only the front stems, so that the clump flowers in tiers.
How much to cut, and how often?
- There are 2 pruning periods a year: March and May. You don’t have to prune in every one.
What does it mean for wildlife?
- Spotted Joe Pye weed flowers in July–September, when it attracts bees and butterflies.
Caution: Do not cut it back in autumn: the stems and seed heads protect the crown and give insects shelter.
