🌱 How to Care for Grey Star to Prevent Whiteflies?

💧 How to Water

Water every 7 days on average during the growing season, reducing frequency in winter. Always check the soil first — 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.

☀️ 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.

🪴 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.
