Bearded iris — October
Check this first
Bearded iris should not be cut down like a clump of grass now. Keep healthy leaf fans and selectively remove only yellow, dead or damaged leaves.
Pay attention to this
- Do not cut into the thick surface rhizome.
- Remove only poor leaves; healthy fans do not need trimming to a point.
- Keep the top of the rhizome free of wet accumulated leaves.
Frequently asked questions
- Must bearded iris be cut to 15 cm after flowering?
- Not during routine care. Shortening leaves can be part of division and transplanting; it is not an annual pruning rule.
- Where do I cut the flower stalk?
- After the last flower, as low as practical among the leaves without damaging the rhizome or leaf fans.
- Will pruning fix a soft rhizome?
- No. That may indicate rot. Assess drainage and damage; do not treat it as routine shaping.
