How to Plant and Grow Coleus
Plant Coleus Seeds: Sow seed in cell packs or flats, use a sterilized soil-less mix. Press seeds into soil, do not cover. Needs light to germinate. Kept at 70-75°F., seedlings emerge in 10-14 days. Transplant seedlings of dwarf coleus into the garden 9 to 12 in. apart. Plant larger coleus varieties 12 to 18 in. apart.
Grow Coleus: Part sun to light shade. Rich, moist soil. The Premium Sun series of coleus will tolerate full sun in many areas, prefers part shade in the low humidity climates common to the Western United States. Remove coleus flowers as they form to keep foliage visible, healthy and growing. Near the end of the season, allow some of the nectar-rich flowers to form. Blooms will attract hummingbirds and butterflies. Coleus is an excellent container plant and can even be grown in a brightly lit window indoors.
