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

💧 How to Water

Water only when the substrate is almost completely dry—on average every 10 to 15 days, and even less frequently in winter. Never allow water to sit in the pot's saucer: excess moisture is the primary cause of root rot in this species.

☀️ Lighting

Prefers full sun to well-lit partial shade. It tolerates direct outdoor sun well; indoors, keep it near a bright window—low light causes the stem to become leggy and weak.

🪴 Ideal Soil

Use a light, well-drained substrate, mixing equal parts garden soil, coarse sand, and perlite (or a ready-made cactus and succulent mix). The ideal pH is neutral to slightly acidic (6.0 to 7.5). Avoid compacted or waterlogged soils.
