Cover the top of the tray with the clear dome that came with your seed starting tray, or cover your pots with clear plastic wrap. This helps keep the potting soil moist. New seeds need to be kept warm; place seed trays or pots in a warm location, but out of direct sunlight.
For faster germination use a heating mat made specially for starting seeds under the tray or pots. Don’t have a heating mat? No problem, you can also sit the containers on top of a warm spot such as the top of the refrigerator. Check regularly for signs of growth. Once germination begins and seedlings start to sprout, remove the plastic wrap.
