Apply neem oil solution (1-2 tbsp per quart water with mild soap) every 5-7 days
Step 3
Use insecticidal soap spray covering all leaf surfaces, repeat every 3-4 days
Step 4
Release beneficial insects: Encarsia formosa wasps, ladybugs, or lacewing larvae

π± How to Care for Bitter Orange to Prevent Whiteflies?
π§ How to Water
Water deeply every 7-10 days during summer, allowing the soil surface to dry slightly between sessions. Reduce to every 14 days in winter. Never leave the roots in waterlogged soil as this causes root rot rapidly.
βοΈ Lighting
Requires full sun with at least 6-8 hours of direct sunlight daily. More light means more abundant flowering and fruiting. Not suitable for indoor growing without intense artificial lighting.
πͺ΄ Ideal Soil
Prefers loamy, well-draining soil rich in organic matter, pH 5.5-7.5. In clay soils, incorporate coarse sand and compost to improve drainage. Apply mulch around the base to retain moisture without waterlogging the crown.
