💧 How to Water
Water every 7-14 days, allowing the topsoil to dry slightly between waterings. Avoid waterlogging — consistently wet roots promote root rot. Apply mulch around the base to retain moisture during dry spells.
☀️ Lighting
Requires full sun, at least 6-8 hours of direct sunlight daily. Insufficient light significantly reduces fruit production. The tree is shade-intolerant.
🪴 Ideal Soil
Prefers well-draining, light to medium-textured soil. pH between 5.5-7.0. Avoid heavy clay or compacted soils that retain excess moisture.
