🌱 How to Care for Chinese Money Plant to Prevent Rust?

💧 How to Water

Water thoroughly when the top 2-3 inches of soil are dry. Allow excess water to drain completely - never let the plant sit in water. Drooping leaves indicate the plant needs water. Use filtered or dechlorinated water if possible, as this plant is sensitive to chemicals in tap water.

☀️ Lighting

Prefers bright, indirect light from an east or west-facing window. Avoid direct sunlight which can cause yellow spots or leaf burn. The plant will lean toward the light source, so rotate it weekly for balanced growth. Can tolerate medium light but will grow more slowly.

🪴 Ideal Soil

Use a well-draining potting mix. A combination of regular potting soil and cactus soil in equal parts works well. Adding perlite or pumice improves drainage. Good drainage is essential to prevent root rot.
