🌱 How to Care for Tahitian Screwpine to Prevent Thrips?

💧 How to Water

Water every 10 days, allowing soil to dry slightly between waterings. Extremely drought-tolerant — overwatering is more harmful than underwatering. In pots, ensure excellent drainage to prevent root rot.

☀️ Lighting

Requires bright to full sun (30,000–80,000 lux). Indoors, place near a south or west-facing window with abundant light. Avoid prolonged shade, which weakens growth and reduces ornamental appeal.

🪴 Ideal Soil

Prefers sandy, light, well-drained soil with a pH of 6.0–8.5. Tolerates saline and alkaline coastal soils — ideal for seaside gardens. Avoid heavy clay soils that retain excess moisture.
