🌱 How to Care for Jungle Geranium to Prevent Anthracnose?

💧 How to Water

Water thoroughly when the top inch of soil feels dry, approximately every 7 days. Never allow the pot to sit in standing water — ixora is sensitive to overwatering. Reduce watering in winter. Always water at the base of the plant to prevent fungal issues on foliage.

☀️ Lighting

Ixora requires full sun — at least 6 hours of direct sunlight daily — for abundant flowering. It can tolerate partial afternoon shade in very hot climates. Insufficient light results in sparse blooming and leggy growth.

🪴 Ideal Soil

Plant in fertile, well-draining, acidic soil with pH 5.0–5.5. Amend with peat moss or compost to improve drainage and acidity. Avoid alkaline soils — iron/manganese chlorosis develops rapidly, causing yellowing leaves. Ixora is notably pH-sensitive.
