European Columbine problems — and how to fix them

European Columbine (Aquilegia vulgaris) is generally forgiving once you match its basics, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.

Leaf miner

Columbine leaf miners tunnel pale, meandering trails through the leaves. Damage is purely cosmetic; cut foliage to the ground after flowering and the plant regrows cleanly.

Powdery mildew

Grey-white mildew forms on stressed, dry or overcrowded plants. Shear back spent foliage after bloom, water at the base, and ensure good spacing for airflow.

Prolific self-seeding

It seeds abundantly and hybridises freely, so colours and forms drift over generations. Deadhead before pods open to control the spread and keep desired colours true.

Short-lived crowns

Individual plants are often short-lived, lasting only a few years. Allow some self-seeding so replacement seedlings maintain the planting naturally over time.
