🌱 How to Care for African Milk Bush to Prevent Aphids?

💧 How to Water

Water only when the potting mix is almost completely dry. In summer, approximately every 7–10 days; in winter, reduce to every 15–20 days. Never allow the plant to sit in waterlogged soil — overwatering is the primary cause of death for this species and leads rapidly to root rot.

☀️ Lighting

African Milk Bush thrives in full sun (at least 6 hours of direct sunlight daily) and will reward you with vigorous growth and dense foliage. It tolerates bright indirect light indoors near sunny windows or on bright balconies, but may become etiolated and leggy in low light conditions.

🪴 Ideal Soil

Use an extremely well-draining mix: equal parts potting soil, coarse sand, and perlite works well. Avoid any soil that retains moisture for extended periods. Ideal pH range is 6.0–8.0. Always plant in pots with drainage holes and never use sealed saucers.
