Watermelon Coleus Care Tips

Watermelon Coleus Care Tips

Growing watermelon coleus, also known as Solenostemon scutellarioides, is a popular choice for gardeners looking to add a splash of vibrant color to their outdoor spaces. This striking plant features brightly colored foliage that resembles the rind of a watermelon, hence its name. To ensure your watermelon coleus thrives and remains beautiful throughout the growing season, follow these essential care tips:

Light and Location

Watermelon coleus thrives in part shade to full shade conditions. It is essential to provide adequate shade, especially during the hottest parts of the day, to prevent the leaves from scorching. If grown in full sun, the colors of the foliage may fade, so it is best to place your watermelon coleus in a location where it can receive dappled sunlight or morning sun and afternoon shade.


Soil and Watering

Watermelon coleus prefers well-draining, moist soil rich in organic matter. Ensure the soil is consistently moist but not waterlogged to prevent root rot. Water the plant regularly, especially during hot and dry periods, but be careful not to overwater. Mulching around the base of the plant can help retain soil moisture and regulate temperature.


Feed your watermelon coleus with a balanced liquid fertilizer every 2-3 weeks during the growing season to promote healthy growth and vibrant foliage color. Fertilizers high in nitrogen can encourage lush foliage production, while those with higher levels of potassium can enhance the plant's overall health and resilience.

Pruning and Pinching

To encourage bushier growth and prevent legginess, regularly pinch back the tips of the stems on your watermelon coleus. This practice promotes branching and leads to a fuller, more compact plant. Additionally, removing any flower spikes that form can redirect the plant's energy into foliage production, enhancing the visual appeal of the plant.

Pest and Disease Control

Keep an eye out for common pests such as aphids, spider mites, and whiteflies, which can affect the health of your watermelon coleus. Regularly inspect the plant for any signs of pest infestations and treat them promptly with insecticidal soap or neem oil. Additionally, practicing good air circulation and avoiding overhead watering can help prevent fungal diseases such as powdery mildew.

Container Gardening

Watermelon coleus is well-suited for container gardening, making it an excellent choice for patios, balconies, or small outdoor spaces. Choose a container with drainage holes to prevent waterlogging and use a high-quality potting mix to provide the plant with the necessary nutrients. Regularly check the moisture levels in the soil and adjust your watering schedule accordingly.


If you live in a region with cold winters, consider overwintering your watermelon coleus indoors. Before the first frost, carefully dig up the plant and transfer it to a pot. Place the pot in a sunny location indoors and continue to care for the plant as usual. With proper maintenance, your watermelon coleus can thrive indoors during the winter months and be ready to return outdoors in the spring.

By following these care tips, you can enjoy the beauty of watermelon coleus in your garden or outdoor space throughout the growing season. With its stunning foliage and relatively low maintenance requirements, watermelon coleus is a fantastic choice for adding a pop of color and visual interest to your landscape.
