Pelargonium 'Paul Crampel' problems — and how to fix them
Pelargonium 'Paul Crampel' (Pelargonium 'Paul Crampel') 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.
Legginess
Vigorous growth runs to bare stems without pruning. Pinch growing tips in spring and cut back hard before overwintering to keep a bushy shape.
Pelargonium rust
This older variety is prone to rust: brown pustules form under the leaves in damp air. Remove infected leaves promptly and improve ventilation.
Reduced flowering
Shade or nitrogen-rich feeding cuts blooms. Give full sun and use a high-potash feed to keep the scarlet flower heads coming.
Grey mould (botrytis)
Cool, damp air and spent flowers cause grey rot. Deadhead regularly and avoid wetting the foliage when watering.
