🌱 How to Care for Snake Plant to Prevent Anthracnose?

💧 How to Water

Allow the soil to dry out completely between waterings — test 5 cm deep before watering. In the growing season (spring/summer), water every 14–21 days. In winter, reduce to once every 4–6 weeks. Always empty the saucer — never let roots sit in standing water.

☀️ Lighting

Adapts to nearly any light condition, from dim corners to bright indirect light near windows. Bright indirect light (150–300 foot-candles) produces the fastest growth and most vibrant coloration. Avoid prolonged intense direct sunlight, which causes irreversible bleaching and leaf scorch.

🪴 Ideal Soil

Use a well-draining cactus or succulent mix, or combine standard potting soil with perlite (50:50 ratio). Ideal pH is 6.0–8.0. Good drainage is the single most important factor — soggy soil causes root rot rapidly. Unglazed terracotta pots enhance moisture evaporation.
