Small-Flowered Cranesbill problems — and how to fix them
Small-Flowered Cranesbill (Geranium pusillum) 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.
Poor flowering in rich soils
In fertile or recently manured ground, plants produce abundant foliage but very few flowers. Move to a lean, well-drained spot or avoid amending the soil with compost or fertiliser.
Powdery mildew
White powdery deposits may develop on the softly hairy leaves during warm, dry periods with low airflow. Remove affected growth; no chemical treatment is usually needed on this small annual.
