🌱 How to Care for Loquat to Prevent Scale Insects?

💧 How to Water

Water deeply and regularly while the tree is young or during dry spells, letting the top few centimeters of soil dry out between waterings. Established trees are fairly drought tolerant, but consistent moisture during flowering and fruit development improves fruit size and quality.

☀️ Lighting

Give loquat full sun for the best flowering and fruit production, though it also grows, flowers, and fruits acceptably in partial shade.

🪴 Ideal Soil

Plant in well-drained, slightly acidic to neutral soil (roughly pH 5.5-7.5). Loquat tolerates sandy, loamy, or clay soils as long as water does not pool around the roots, since soggy soil quickly leads to root rot.
