🌱 How to Care for Tree Stonecrop to Prevent Mealybugs?

💧 How to Water

Water thoroughly during spring and summer, waiting for the soil to dry out completely between waterings. Cut back drastically in autumn and winter, watering only enough to prevent the leaves from shriveling. Never let the plant sit in soggy soil.

☀️ Lighting

Provide as much direct sunlight as possible — at least 6 hours a day. Indoors, place it in the brightest south-facing window available; insufficient light causes weak, leggy, stretched growth.

🪴 Ideal Soil

Use a fast-draining succulent or cactus mix combining loamy or sandy soil with perlite, pumice, or coarse sand. Unglazed terracotta pots help excess moisture evaporate faster and reduce the risk of root rot.
