Spray plants with strong water jet to dislodge whiteflies, focusing on leaf undersides
Step 2
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

- ✓ Use reflective mulch around susceptible plants (confuses whiteflies)
- ✓ Install insect-proof screens on greenhouse vents and doors
- ✓ Maintain good air circulation between plants

🌱 How to Care for Key Lime to Prevent Whiteflies?
💧 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.
