🌱 How to Care for Hairy Coleus to Prevent Thrips?

💧 How to Water

Let the top inch (2.5 cm) of soil dry out between waterings. Its semi-succulent stems store water, so it tolerates missed waterings far better than soggy, waterlogged soil, which quickly leads to root rot.

☀️ Lighting

Place it within about 3 feet of a bright window, or outdoors in a spot with morning sun and afternoon shade. Too little light causes leggy growth and leaf drop.

🪴 Ideal Soil

Use a well-draining potting mix enriched with organic matter (such as compost or coco coir), plus perlite or coarse sand to keep the roots from sitting in moisture.
