Geranium himalayense 'Gravetye' problems — and how to fix them
Geranium himalayense 'Gravetye' (Geranium himalayense 'Gravetye') 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.
Powdery mildew
Grey film on foliage in late summer dry spells. Increase airflow, water at the roots, and shear clumps back to prompt fresh, clean leaves.
Post-flowering decline
After the early-summer flush growth can sprawl and brown. Cut the plant back hard to regenerate compact foliage and often a second wave of bloom.
Vine weevil
Larvae attack roots of potted plants, causing wilting. Check rootballs at repotting and use biological nematode controls if grubs appear.
Reduced bloom in shade
Flowering and the dense habit both depend on good light; in too much shade it blooms less and opens up. Relocate to brighter conditions.
