🌱 How to Care for Chinese jade to Prevent Scale Insects?

💧 How to Water

Water only once the potting mix has dried out completely, roughly every two weeks in spring and autumn, and less often in summer and winter. Always let excess water drain away fully -- soggy soil is the main cause of root rot in this species.

☀️ Lighting

Give it at least four hours of direct sun followed by bright light for the most compact growth and richest chocolate-red coloring. In very hot climates, filter or shade the plant during intense afternoon sun above 30C to prevent leaf burn; if grown indoors, place it in the brightest window available or under supplemental grow lights.

🪴 Ideal Soil

Plant in a fast-draining succulent or cactus mix, or blend your own from potting soil, coarse sand, and perlite or pumice in roughly equal parts. Adding a layer of gravel at the pot base helps water escape quickly and keeps roots from sitting wet.
