Light: Coleus plants thrive in bright, indirect light. If you're growing them indoors, place them near a window where they can receive plenty of natural light without direct sun exposure, which can cause their colors to fade.
Watering: Keep the soil consistently moist but not waterlogged. Coleus plants prefer well-draining soil, so be mindful not to overwater them. Allow the soil to dry out slightly between waterings.
Fertilization: Use a balanced, water-soluble fertilizer every few weeks during the growing season to promote healthy growth and vibrant foliage. Look for a fertilizer with equal parts nitrogen, phosphorus, and potassium.
Pinching and Pruning: Regularly pinching back the growing tips of the plant can encourage bushier growth and prevent legginess. Pruning leggy stems can also help maintain a compact, full shape.
Temperature and Humidity: Coleus plants thrive in warm, humid conditions. If you're growing them indoors, consider using a humidifier to maintain adequate moisture levels, especially during drier seasons.
