π± How to Care for Ritchie's Spurge to Prevent Whiteflies?
π§ How to Water
Water only when the soil is completely dryβcheck 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.
βοΈ Lighting
Provide the plant with bright, direct sunlightβideally 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.
πͺ΄ 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.
