Sow indoors 6-8 weeks before transplanting. Soil seed on the surface of the soil, do not cover as light is required for germination. Provide a soil temperature of 21-24°C (70-75°F). Transplant after all danger of frost is past, 6-8" apart. Coleus can grow under any light condition, shade to full-sun as long as they get plenty of moisture. Pinch and remove flowers to encourage branching and full growth.
