ðą How to Care for Lucky Bamboo to Prevent Gray Mold (Botrytis Blight)?
ð§ How to Water
If grown in soil, water every 14 days and allow the topsoil to dry slightly between waterings. If grown in water, keep roots submerged at all times and change the water every 7â14 days using filtered, distilled, or rainwater â tap water's fluoride and chlorine can cause leaf tip browning over time.
âïļ Lighting
Prefers bright, indirect light (500â2500 lux). Tolerates low-light conditions well, making it ideal for offices and shaded indoor spaces. Avoid direct sunlight, which will scorch the leaves and cause yellowing.
ðŠī Ideal Soil
If planting in soil, use a rich, well-draining potting mix with a pH of 6.0â6.5. A blend of standard potting mix with perlite or coarse sand works well. Avoid heavy, waterlogged soils. Many growers prefer water culture â using pebbles or decorative stones to anchor the stalks in a vase.
