Common Fumitory problems — and how to fix them
Common Fumitory (Fumaria officinalis) 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
Dense stands in dry spells are prone to powdery mildew on foliage; improve air circulation and water at the base rather than overhead.
Uncontrolled self-seeding
On bare, cultivated soil common fumitory self-seeds prolifically and can become a persistent weed; deadhead before seed set or hoe seedlings when small.
