How to Grow Coleus Plant Outdoors

Coleus plants (Plectranthus scutellarioides) are popular ornamental plants that come in a variety of vibrant colors and patterns. They’re easy to grow, making them perfect for both novice and experienced gardeners.

In this article, we’ll discuss how to grow coleus plants outdoors and the best practices to keep them healthy and flourishing.

Choosing the Right Spot

The first step in growing coleus plants is to choose the right spot. Coleus plants thrive in partial or full shade, making them perfect for under trees or in the shade of buildings. They do not do well in direct sunlight as it can cause their leaves to scorch and dry out.

When choosing a spot for your coleus plant, make sure it’s sheltered from strong winds. Coleus plants have fragile stems that can break easily when exposed to strong gusts.

Preparing the Soil

Coleus plants prefer well-draining soil that’s moist but not waterlogged. Before planting your coleus, prepare the soil by adding compost or organic matter to improve its drainage and nutrient content.

If you’re planting your coleus in a container, make sure it has drainage holes at the bottom to prevent water from accumulating at the roots.

Planting Coleus

Planting coleus is easy. Dig a hole that’s slightly larger than the root ball of your plant and place it in the hole. Cover the roots with soil and gently press down to remove air pockets.

If you’re planting multiple coleus plants, make sure they’re spaced at least 12 inches apart to allow room for growth.

Watering

Coleus plants need regular watering to keep their soil moist. However, overwatering can cause root rot and other fungal diseases. Water your coleus deeply once a week or when the top inch of soil feels dry. Avoid getting water on the leaves as it can cause them to rot.

Fertilizing

Coleus plants are heavy feeders and require regular fertilization to keep them healthy and vibrant. Use a balanced fertilizer every two weeks during the growing season (spring to fall) to provide your coleus with the nutrients it needs.

Pruning

Pruning is essential to keep your coleus plant in good shape. Pinch off the tips of new growth to encourage bushier growth and prevent the plant from becoming leggy. You can also remove any yellow or damaged leaves to keep the plant looking its best.

Pests and Diseases

Coleus plants are relatively pest and disease-resistant. However, they can be prone to fungal diseases like powdery mildew if their leaves remain wet for too long. To prevent fungal diseases, water your coleus at the base of the plant and avoid getting water on the leaves.
