Growing Conditions

Coleus (Plectranthus scutellarioides) thrives under specific environmental conditions, ensuring vibrant foliage and healthy growth. Understanding these requirements is essential for maintaining the plant's stunning aesthetics.

Soil Requirements

Coleus prefers well-draining soil with good moisture retention. A mix of potting soil and perlite or sand creates an ideal growing environment. The pH level should range between 6.0 and 7.0, slightly acidic to neutral. Regularly check for compaction, which can hinder water absorption. If planting in a garden bed, incorporate organic matter like compost to improve soil quality and nutrient availability.

Light and Water Needs

Coleus enjoys partial shade, ideally receiving four to six hours of indirect sunlight daily. Too much direct sunlight may scorch its leaves, while too little can dull its colors. Water the plant to maintain consistent moisture in the soil, allowing the top inch to dry out between watering sessions. Ensure containers have drainage holes to prevent waterlogged roots. In general, maintain a humid environment, especially indoors, as coleus responds well to increased humidity.
