Start with the right plants for the right place
For shade gardens, look for labels that say shade or part shade, especially for large-leaf seed types such as Kong. For hot patios or exposed beds, choose sun-tolerant series such as Mezmerize™ or Talavera™, sun/shade FlameThrower™ selections, or Main Street and Great Falls® lines.
What type of Coleus plant to look for when buying
Choose stocky plants with strong color, firm stems, and no signs of wilting. Avoid plants sitting in soggy trays.
Where to plant Coleus
Coleus wants good drainage, whether in the ground or in containers. In beds, improve heavy soil before planting. In pots, use a well-drained container mix and a pot with drainage holes. Poor drainage and excessive watering can lead to stunted plants, muddy brown leaves, and scorched margins.
When to water Coleus
Water thoroughly at planting. For the first week or so, keep the root ball moist but not waterlogged. After establishment, water when the top inch of soil is dry. Containers dry faster than garden soil, especially in midsummer, so check pots often. Water at the base when possible; drip irrigation or a soaker hose keeps foliage drier and helps reduce fungal disease pressure.
Creating a fuller Coleus plant
Pinch young coleus to encourage branching and dense foliage. Many modern vegetative lines are naturally well-branched, but a light pinch can still shape a container. If flower spikes appear and you prefer foliage, shear or pinch them off. Allowing seed set (by not removing the flowers) can make plants decline, while removing flowers can extend performance.
What fertilizer is best for Coleus plants
Feed for foliage rather than blooms. An all-purpose soluble fertilizer is recommended throughout the growing season. Avoid bloom-promoting, high-phosphorus formulas because they can encourage legginess and flowering. In mixed containers, pair coleus with plants that like similar moisture and light. Excellent partners include begonias, impatiens, sweet potato vine, caladium, ornamental grasses, and shade-tolerant annuals. Coleus are tender. In cold-winter regions, frost ends the outdoor show.
