π± How to Care for Loquat to Prevent Scale Insects?
π§ How to Water
Water regularly during the first two years to encourage root establishment. Once established, the tree tolerates short periods of drought. During extreme heat, water deeply every 10-14 days. Avoid waterlogging, as root rot is its main threat in poorly drained soils.
βοΈ Lighting
It needs full sun (minimum 6-8 hours of direct sunlight daily) to flower and fruit abundantly. In partial shade, the tree will grow, but fruit production will be significantly reduced. Ideal for south or southeast orientation in the northern hemisphere.
πͺ΄ Ideal Soil
It prefers fertile, deep, and well-drained soils, with a pH between 5.5 and 7.5. It tolerates clayey or sandy soils as long as drainage is adequate. Amend with organic matter when planting. Apply a layer of mulch to retain moisture and regulate soil temperature.
