Troubleshooting
Geranium renardii problems — and how to fix them
Geranium renardii (Geranium renardii) 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.
Rot in wet soil
Crown and roots rot in heavy, poorly drained or wet ground. Plant in sharply drained, gritty soil and never overwater; raised or gravelly sites suit it best.
Sparse flowering
It can flower modestly, valued mainly for foliage. Full sun and lean soil maximise the bloom; excess feeding or shade reduces it further.
Floppy, open growth in shade or rich soil
Loses its neat form and sprawls when too well fed or shaded. Grow hard in sun on poor, gritty soil to keep the tight, textured mound.
Powdery mildew in dry, still air
Pale film on leaves during hot dry spells. Shear back affected foliage and improve air movement to prompt clean regrowth.
