ðą How to Care for Dracaena to Prevent Anthracnose?
ð§ How to Water
Water every 10â14 days in summer, every 3â4 weeks in winter. Always allow the top 2â4 cm of soil to dry out before watering again. Use filtered or rain water if possible â fluoride in tap water causes brown leaf tips. Never let the plant sit in standing water.
âïļ Lighting
Dracaenas prefer bright, indirect light (500â2500 lux). They tolerate low-light conditions well but grow more vigorously and maintain vibrant foliage colour in medium indirect light. Avoid direct afternoon sun, which scorches leaves. Variegated varieties benefit from slightly brighter conditions.
ðŠī Ideal Soil
Use a well-draining, slightly acidic potting mix (pH 6.0â6.5). A standard indoor potting mix amended with perlite or coarse sand works well. Ensure the pot has drainage holes to prevent waterlogging, which is the leading cause of root rot in Dracaena.
