🌱 How to Care for Tung Oil Tree to Prevent Scale Insects?

💧 How to Water

Water every 7–14 days during the growing season, allowing the top 2–3 cm of soil to dry out between waterings. The Tung Oil Tree is sensitive to waterlogged soil, which can quickly lead to root rot. Reduce watering significantly in winter when the tree is dormant.

☀️ Lighting

Requires full sun (at least 6–8 hours of direct sunlight per day). Position in an open area away from taller structures that could shade it. Young trees may tolerate light partial shade but will perform best and flower most prolifically with maximum sun exposure.

🪴 Ideal Soil

Prefers well-drained, fertile loamy soil with a slightly acidic to neutral pH between 6.0 and 6.5. Avoid heavy clay or constantly wet soils. Amending with organic matter such as compost improves drainage and fertility. Liming acidic soils to the appropriate pH range greatly benefits this species.
