🌱 How to Care for Madagascar Coleus to Prevent Aphids?

💧 How to Water

Water when the top inch of soil feels dry, approximately every 7 to 10 days. Reduce watering frequency in winter when growth slows. Never allow the pot to sit in standing water, as this leads to root rot. Use room-temperature water for best results.

☀️ Lighting

Prefers bright indirect light or dappled shade. Place near an east- or west-facing window indoors. Avoid intense direct afternoon sun, which can scorch the leaves. Outdoors, a lightly shaded position under trees or on a shaded patio works well.

🪴 Ideal Soil

Use a lightweight, well-draining potting mix amended with perlite or coarse sand. Ideal soil pH is 6.0 to 7.0. Good drainage is essential to prevent root rot. Avoid heavy clay soils or dense compacted mixes that retain excess moisture.
