Troubleshooting
Geranium clarkei 'Kashmir White' problems — and how to fix them
Geranium clarkei 'Kashmir White' (Geranium clarkei 'Kashmir White') 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.
Vigorous spread
Its running rhizomes can outgrow their space and crowd neighbours in good soil. Lift and divide every two to three years to control the clump and reinvigorate it.
Powdery mildew
Grey film on foliage in late-summer dry spells. Improve airflow, water at the base, and shear clumps back hard to bring up clean new leaves.
Mid-season flop
After flowering the growth can sprawl and look tired. A hard cut-back refreshes the foliage and often triggers a lighter second flush.
Vine weevil
Larvae feed on roots and rhizomes of potted plants, causing wilting. Check rootballs at repotting and use nematode controls if grubs are present.
