Big-root cranesbill forms an often semi-evergreen carpet. Remove old leaves and spent stems selectively; do not routinely shear healthy winter foliage bare. The months are a guide for gardens in the Netherlands and Belgium; growth stage and weather take priority.
Big-root cranesbill — October
Check this first
Leave healthy big-root cranesbill foliage intact. Its thick creeping rhizomes need no annual pruning; address only damage or unwanted spread.
Pay attention to this
- Do not cut into the thick rhizomes when tidying foliage.
- Red or bronze winter foliage is not necessarily dead.
- Restrict spread at the edge; cutting flowers does not stop rhizomes spreading.
Frequently asked questions
- Must the winter leaves come off?
- Only tired, dead or damaged leaves. Big-root cranesbill can retain much of its foliage in mild winters.
- What should I cut after flowering?
- Cut spent flower stems back among the foliage and remove tired leaves individually.
- Why does it keep spreading after pruning?
- The plant spreads by rhizomes. Cutting top growth temporarily reduces foliage but does not contain the rhizomes.
