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
