Troubleshooting
Licorice plant problems — and how to fix them
Licorice plant (Helichrysum petiolare) 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.
Root rot
The most frequent problem; caused by waterlogged soil or containers without drainage holes. Use very free-draining compost and never allow the pot to sit in water.
Botrytis (grey mould) on foliage
Fluffy grey mould develops on the felted leaves in cool, damp conditions. Increase air circulation, remove affected leaves promptly, and avoid overhead watering.
Leggy, sparse growth
Occurs in insufficient light. Move to a sunnier spot and pinch growing tips regularly to encourage dense, bushy growth.
