🌱 How to Care for Blue Coleus to Prevent Mealybugs?

💧 How to Water

Water when the top 2-3 cm of soil feel dry, approximately every 10-14 days. In hot weather, water every 8-10 days; in winter, every 14-18 days. Avoid waterlogging — the plant is susceptible to root rot. Always allow excess water to drain freely from the pot.

☀️ Lighting

Full sun to partial shade. Outdoors, it thrives in direct sunlight. Indoors, place within 50 cm of an east or west-facing window. Morning sun is ideal; protect from intense midday sun in very hot climates. Insufficient light reduces fragrance and flowering.

🪴 Ideal Soil

Use a light, well-draining mix. Combine quality potting mix with 30-40% perlite or coarse sand. Ideal pH range: 6.0–7.5. Avoid heavy clay soils or any mix that retains excess moisture around the roots.
