Tips for Growing Tomatoes Indoors. How to sow tomato seed: Fill seed trays or small pots with moist, sterilized potting mix. Drop the seeds 1 in (2.5 cm) apart over the soil. Tomato seeds need light and warmth to germinate, so cover the seeds lightly -- never more than 1/4-in (.5 cm) -- with potting medium. Water and cover. Then, spray with water until thoroughly moist. Mist as needed to keep the medium moist at all times.
Tomatoes are a warm-season annual that grow best when the soil temperature is at least 55Â°F and the air temperature ranges between 65Â° and 90Â°F. Tomatoes require from 50 to more than 90 warm, frost-free days to reach harvest. Tomatoes are commonly grown from seedlings started indoors and transplanted into the garden. Start tomato seed indoors as early as 8 to 6 weeks before the average date of the last spring frost. Garden soil is usually warm enough for tomato transplants 2 to 3 weeks after the last frost.
