Pinch off the tops and trim coleus flowers to encourage branching and a bushier, fuller plant. Keep soil moist. Mulching is a good idea. Fertilize every four to six weeks or work in a slow-release fertilizer at planting time. Tear out and discard plants in fall, after frost fells them.
Coleus makes a great houseplant.
Dig up plants and bring them indoors for the winter. Or take cuttings in late fall, root them in a jar of water, and pot them up to plant outdoors in spring. Inc. How things get done. Use of this Web site constitutes acceptance of the eHow Terms of Use and Privacy .
