ðą How to Care for Dwarf Umbrella Tree to Prevent Bacterial Blight?
ð§ How to Water
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.
âïļ 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.
ðŠī Ideal Soil
Use well-draining soil rich in organic matter. A mix of peat moss, perlite, and regular potting soil works well. Ensure pots have drainage holes to prevent root rot from waterlogging.
