Iberian Cranesbill problems — and how to fix them
Iberian Cranesbill (Geranium ibericum) 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
White powdery patches on leaves appear after flowering in warm, dry conditions; cut back spent stems promptly and thin congested clumps to improve air circulation.
Slug and snail damage
Young spring growth is attractive to slugs; use organic iron phosphate pellets or apply a layer of sharp grit around the crown as a physical deterrent.
