🌱 How to Care for Mango Tree to Prevent Scale Insects?

💧 How to Water

Water young trees deeply once or twice a week during the first year. Mature trees are drought-tolerant and should be watered every 7–14 days during dry spells, allowing the soil to dry out well between waterings. Avoid waterlogging, which promotes root rot.

☀️ Lighting

Mango trees require full sun with at least 8 hours of direct sunlight daily. In shaded conditions, trees grow weak and produce fewer fruits. Plant in an open, sunny location away from structures that may block light.

🪴 Ideal Soil

Prefers well-drained sandy loam soils with a pH between 5.5 and 7.5. Avoid heavy clay or poorly drained soils. Amend with coarse sand or perlite if drainage is inadequate.
