ðą How to Care for Painted Nettle to Prevent Fungus Gnats?
ð§ How to Water
Water when the top inch of soil feels dry, approximately every 7 days. Avoid letting the soil dry out completely as coleus wilts quickly. Water at the base of the plant to prevent fungal issues on the foliage. Reduce watering slightly in winter.
âïļ Lighting
Coleus thrives in bright indirect light or partial shade. Direct harsh afternoon sun can fade the foliage colors, though some sun-tolerant varieties can handle full sun with adequate watering. Indoors, place near a bright window with filtered light.
ðŠī Ideal Soil
Use a fertile, well-draining loamy potting mix with slightly acidic to neutral pH (6.0â7.0). A standard potting mix amended with perlite works well. Ensure good drainage to prevent root rot.
