Bee introduces how to plant

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. After all danger of frost transplant into 4 in. containers, or into the garden 12 to 18 in. apart. Direct sowing is not recommended.

Grow Coleus: Part sun to light shade. Rich, moist soil. Remove flowers as they form to keep coleus foliage visible, healthy and growing.
