🌱 How to Care for Curry tree to Prevent Scale Insects?

💧 How to Water

Water when the top 2-3 cm of soil has dried out—this is typically required once a week, or more frequently during warmer months. Avoid standing water at the bottom of the pot, as the curry tree is particularly sensitive to overwatering and root rot.

☀️ Lighting

Provide the brightest spot possible: outdoors it prefers 6+ hours of direct sunlight daily, while indoors you should choose a bright location near a south-facing window. Prolonged lack of light causes the stems to become leggy and the leaves to become sparse and paler.

🪴 Ideal Soil

It requires well-draining, loose, nutrient-rich soil with an ideal pH between 6.0 and 7.5. A mixture of garden soil, compost, and sand or perlite—with good drainage—provides a suitable medium; ensure the pot has drainage holes at the bottom.
