Geranium x oxonianum 'Wargrave Pink' problems — and how to fix them

Geranium x oxonianum 'Wargrave Pink' (Geranium x oxonianum 'Wargrave Pink') 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 and rust

Hot, dry, or congested conditions bring white mildew or orange rust pustules. Shear off affected leaves, improve air circulation, and water at the base rather than overhead.

Flopping and bare centre

After the first heavy flush the clump can sprawl and brown in the middle. A hard shear renews compact foliage and prompts a second bloom.

Self-sown variable seedlings

Open-pollinated seedlings rarely match the parent's colour. Deadhead to reduce stray seedlings and propagate only by division to keep 'Wargrave Pink' true.

Slug and snail damage

Soft spring growth is grazed in wet weather. Protect emerging shoots with barriers or pet-and-wildlife-safe controls until the foliage hardens.
