Care & Maintenance

Watering & Feeding

• Water moderately; allow soil to dry slightly between waterings

• Feed every 2–3 weeks with a liquid fertiliser

Deadheading

• Remove spent blooms to encourage continuous flowering

• Pinch back leggy growth to maintain shape

Overwintering

• Bring potted geraniums indoors or to a frost-free greenhouse

• Reduce watering but don’t let soil dry out completely

Common Problems

• Botrytis (grey mould): Keep foliage dry and ensure good airflow

• Aphids & whitefly: Treat with insecticidal soap or neem oil

• Leggy growth: Regular pruning and deadheading
