🌱 How to Care for Ritchie's Spurge to Prevent Scale Insects?

💧 How to Water

Water only when the soil is completely dry—check by sticking your finger deep into the pot. During the growing season (spring to fall), watering about once a week is usually sufficient, while in winter, you should reduce this to once a month or only when the plant shows signs of shriveling. Avoid standing water in the pot, as this quickly leads to root rot.

☀️ Lighting

Provide the plant with bright, direct sunlight—ideally at least 6 hours daily. A south-facing window or supplemental grow lights indoors work well. Gradually acclimate the plant to full sunlight to avoid sunburn.

🪴 Ideal Soil

Use a very well-draining soil mix, such as cactus/succulent soil amended with pumice, perlite, or coarse sand. The pot must have drainage holes so the roots never sit in damp soil.
