🌱 How to Care for Dracaena to Prevent Scale Insects?

💧 How to Water

Water every 10–14 days in summer, every 3–4 weeks in winter. Always allow the top 2–4 cm of soil to dry out before watering again. Use filtered or rain water if possible — fluoride in tap water causes brown leaf tips. Never let the plant sit in standing water.

☀️ Lighting

Dracaenas prefer bright, indirect light (500–2500 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.

🪴 Ideal Soil

Use a well-draining, slightly acidic potting mix (pH 6.0–6.5). 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.
