Pelargonium tomentosum problems — and how to fix them
Pelargonium tomentosum (Pelargonium tomentosum) 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.
Leaf scorch in full sun
The soft, hairy leaves bleach and crisp under intense sun; site it in bright shade or morning-only sun rather than baking exposure.
Wilting between waterings
Big thin leaves lose water fast and flop when dry; keep soil lightly moist and never let it bone-dry, while still ensuring drainage.
Grey mould on felted leaves
The dense hairs trap moisture, so botrytis sets in if leaves stay wet or air is stagnant. Keep foliage dry and improve airflow.
Sprawling, untidy habit
Its naturally lax, spreading growth can look messy; pinch tips and trim back regularly to keep a fuller mound, or let it cascade from a raised pot.
