Cut-Leaved Cranesbill problems — and how to fix them
Cut-Leaved Cranesbill (Geranium dissectum) is generally low-drama, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Powdery mildew
A common problem on the fine, hairy foliage in dry conditions. Water at the base rather than overhead, space plants well to improve airflow, and remove affected leaves promptly.
Prolific self-seeding
Capable of spreading rapidly in cultivated ground via self-sown seeds. Deadhead before seed is set to limit unwanted spread, particularly in vegetable beds or borders where it can become a weed.
