🌱 How to Care for Dwarf Umbrella Tree to Prevent Pythium Root Rot?

Water when 75% of the soil volume is dry. Allow water to soak slowly until it flows through drainage holes. Yellow leaves often indicate overwatering - let soil dry more between waterings.

☀️ Lighting

Prefers bright indirect light but tolerates lower light conditions. Avoid direct sunlight which can scorch leaves. In low light, growth slows and plant may become leggy. A spot near a north or east-facing window is ideal.

🪴 Ideal Soil
