When to Plant Coleus

Introduction

Coleus, also known as painted nettle, is a colorful and easy-to-grow plant that is often used as an ornamental foliage in gardens and landscapes. It is a popular choice among gardeners due to its beautiful range of foliage colors and patterns that add a splash of vibrancy to any garden. However, it is important to know the right time to plant coleus to ensure optimal growth and development. In this article, we'll provide some tips on when to plant coleus, and how to care for it throughout its growth cycle.

Season for Planting Coleus

The best time to plant coleus is during the late spring or early summer when the soil temperature is consistently above 60掳F (15掳C). Coleus is a tropical plant that does not tolerate cold temperatures, so it is important to wait until the risk of frost has passed before planting outdoors. If you live in an area with a shorter growing season, you can start coleus seeds indoors about 10 weeks before the last frost date and transplant them outdoors once the temperatures warm up.

Choosing a Planting Location

Coleus prefers well-draining soil that is rich in nutrients. Choose a location that receives partial shade to full shade, as direct sunlight can cause the leaves to scorch and fade. You can plant coleus in containers or directly in the ground, depending on your preference. If you choose to plant in a container, make sure it has drainage holes to allow excess water to drain out.

Planting and Care Tips

When planting coleus, gently loosen the soil in the planting bed or container, and mix in some organic matter, such as compost or well-rotted manure. Space the plants about 12-18 inches apart to allow for adequate air circulation and growth. Water the plants regularly, keeping the soil moist but not waterlogged. Fertilize every two weeks during the growing season with a balanced fertilizer, such as a 10-10-10 or 20-20-20 formula. Remove any wilted or dead leaves regularly to encourage new growth.

Overwintering Coleus

Coleus is often grown as an annual in cooler climates, but can be overwintered indoors in frost-free areas. To do this, dig up the plant before the first frost and shake off any excess soil. Cut the stems back by about one-third and place the plants in pots filled with fresh potting soil. Water the plants and place them in a sunny window or under grow lights. Keep the soil moist but not waterlogged, and fertilize every two weeks with a balanced fertilizer. In the spring, replant the coleus outdoors after the danger of frost has passed.

Conclusion

Planting coleus is a great way to add color and interest to your garden or landscape. By choosing the right season, planting location, and providing adequate care and maintenance, you can ensure healthy and vibrant plants that will thrive throughout the growing season. Whether grown as an annual or overwintered indoors, coleus is a versatile and beautiful addition to any garden.
