🌱 How to Care for Fragile Crassula to Prevent Aphids?

💧 How to Water

Apply the "soak and dry" method: water thoroughly only when the substrate is completely dry. In winter, reduce watering even further; it is very sensitive to waterlogging, which causes root rot.

☀️ Lighting

Place in a very bright spot with a few hours of direct sun in the morning or late afternoon; a south-facing exposure or a position near a bright window is ideal. Gradually acclimate the plant to full sun to avoid leaf scorch.

🪴 Ideal Soil

Use a fast-draining mineral substrate: a mix of 50% potting soil and 50% coarse sand, pumice, or perlite, in a pot with large drainage holes.
