🌱 How to Care for Neem to Prevent Mealybugs?

💧 How to Water

Water young trees regularly (every 7–14 days) during the first 2–3 years of establishment. Once mature, neem trees are highly drought-tolerant and rely on deep roots to access subsoil moisture. Avoid overwatering, which leads to root rot.

☀️ Lighting

Neem requires full sun and thrives in direct sunlight for 6–8+ hours per day. Seedlings can tolerate partial shade initially, but mature trees need maximum light to grow vigorously and produce seeds.

🪴 Ideal Soil

Plant in deep, well-draining loamy or sandy-loam soil. Neem tolerates poor, rocky, and even slightly saline soils. Avoid heavy clay or waterlogged conditions. Ideal soil pH is 5.5–7.5.
