Meadowsweet: when to prune it?

After flowering, in August, and the dead stems in March.

What else to prune in those months? March · August

In August, cut off the spent plumes to limit self-seeding.
If the leaves are brown or grey with mildew after flowering, cut the whole plant back to 10 cm: fresh new foliage soon follows.
In a wildlife garden, leave a few stems over winter as shelter for insects.
In March, cut all old stems back to just above the ground.

There are 2 pruning periods a year: March and August. You don’t have to prune in every one.

Meadowsweet 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.
As a native plant, it feeds more insects than a non-native species.

Caution: In wet soil it self-seeds readily: remove the plumes in time if you do not want seedlings.
