ðą How to Care for Grey Star to Prevent Spider Mites?
ð§ How to Water
Water every 7 days on average during the growing season, reducing frequency in winter. Always check the soil first â water only when the top 2-3 cm feel dry. Use filtered or distilled water, or leave tap water out overnight to let chlorine and fluoride evaporate, as these can cause brown leaf tips.
âïļ Lighting
Place the Grey Star in bright to medium indirect light, such as near a window with sheer curtains. Avoid direct sunlight, which can scorch leaves and fade the beautiful silver pattern. In low-light conditions, the variegation may diminish over time.
ðŠī Ideal Soil
Use a well-draining, nutrient-rich potting mix. A blend of standard potting soil and perlite (2:1 ratio) works well. Target a soil pH between 6.1 and 7.3. Always ensure the pot has drainage holes to prevent waterlogged roots.
