Pruning japanese astilbe — FAQ
When should I prune japanese astilbe?
Late autumn after foliage dies back, or early spring. Cut stems to just above ground level with shears. Optional: deadhead immediately after flowering to prevent self-seeding and keep the plant looking tidy through late summer.
How often does japanese astilbe need pruning?
Annually; divide every 3–4 years to maintain vigour. Japanese astilbe needs little pruning beyond an annual cutback. Remove spent flower spikes promptly if you want the plant to put energy into foliage, or leave them for winter texture. Cut all growth to ground level in late autumn or early spring. Like all astilbes, periodic division is more rejuvenating than pruning.
