🌱 How to Care for Silver Jade Plant to Prevent Leaf Spot?

💧 How to Water

Water only when the substrate is completely dry, every 10 to 21 days in summer and every 30 to 60 days in winter. Use the 'soak and dry' method: soak the pot thoroughly until water drains from the bottom, then wait for the substrate to dry out completely before watering again. Never leave the plant sitting in water.

☀️ Lighting

Place the Silver Jade in a location with plenty of direct sunlight, at least 6 to 8 hours a day. A south or west-facing window is ideal. Without enough light, the leaves lose their characteristic silvery color and growth becomes leggy and weak.

🪴 Ideal Soil

Use a specific substrate for succulents and cacti with excellent drainage. Mix with perlite or coarse sand to ensure root aeration. Never use regular garden soil, as it retains excessive moisture and promotes root rot.
