ðą Care Guide: Mango Tree
ð§ 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 7â14 days during dry spells, allowing the soil to dry out well between waterings. Avoid waterlogging, which promotes root rot.
âïļ 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.
ðŠī 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.
