Start dahlia seeds indoors eight to 10 weeks before transplanting outdoors. Transplant outdoors four weeks after the last frost or when the soil and air are consistently warm. Dahlias need full sun and a deep, loose soil. 1 Fill small pots, cell packs or peat pots with starting medium to 1 inch from the top. 2 Place the dahlia seeds in the center of the pots and cover with about 1/2 inch of soil. 3 Water the pots so that the soil is thoroughly moist. Discard any water that drains through. 4 Cover the pots with plastic wrap and set them in a warm place out of direct sunlight. 5 Remove the plastic wrap when the seeds germinate. Germination may take about a week. 6 Move the seedlings to a sunny window or use artificial lighting. Dahlia seedlings need a lot of light, so a south-facing window is best. 7 Monitor the soil moisture and add water as necessary. The soil should be moist but not soggy.
