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

ðą How to Care for Lesser Periwinkle to Prevent Whiteflies?
ð§ How to Water
Water deeply once a week during the first growing season to help roots establish. Once the plant is established, reduce watering to every 10â14 days. Avoid waterlogging, as consistently wet soil promotes root rot and stem blight.
âïļ Lighting
Lesser periwinkle thrives in partial shade to dappled sunlight. It tolerates deep shade better than most ornamental ground covers. In cooler climates it handles full sun, but in warm regions afternoon shade is beneficial to prevent leaf scorch.
ðŠī Ideal Soil
Plant in well-draining soil with a pH of 6.0â8.0. Lesser periwinkle tolerates a wide range of soil types including sandy, loamy, and clay soils. Amend with organic compost at planting to improve structure and moisture retention.
