🌱 How to Care for Croton to Prevent Thrips?

💧 How to Water

Water when the top 2-3cm of soil feels dry, typically every 5-7 days. Ensure thorough watering until water drains from the bottom, but never let the plant sit in water. Reduce watering in winter.

☀️ Lighting

Place in bright, indirect light for 6-8 hours daily. Morning sun is acceptable, but protect from intense afternoon rays. Insufficient light will cause leaves to lose their vibrant colors and revert to green.
