How to care for Coleus
Water
Water Coleus plants thoroughly, allowing the top inch of the soil to dry out between waterings. They prefer consistently moist but not soggy soil. Overwatering or poor drainage can lead to root rot, so ensure adequate drainage. In drier conditions, mist the leaves occasionally to maintain humidity.
Light
Provide bright, indirect sunlight for optimal growth. Coleus can tolerate partial shade but vibrant leaf colors are best maintained with adequate light. Direct sunlight might fade the colors, so if placed outdoors, partial shade to filtered sun is recommended.
Nutrients
Coleus plants benefit from regular fertilization during the growing season. Use a balanced, water-soluble fertilizer every two weeks, diluted to half the recommended strength. Avoid high nitrogen fertilizers, which can dilute the leaf colors. During winter or non-active growing periods, reduce fertilization to once a month.
Temperature
Coleus thrives in temperatures between 60-75°F (15-24°C). Protect the plant from cold drafts and frost, as it is sensitive to extreme cold. Indoor plants should be kept away from heating vents and air conditioners to avoid sudden temperature fluctuations.
