Starting Tomato Seeds Indoors

To get a head start on the growing season, many gardeners in Kansas City, MO start their tomato plants indoors. You can start tomato seeds indoors four to six weeks before the last frost date. Choose a sunny spot in your home, such as a south-facing window or a grow light setup, and sow the seeds in a high-quality seed starting mix. Keep the soil moist, but not waterlogged, and maintain a temperature of around 70 degrees Fahrenheit.

Transplanting Tomato Seedlings to the Garden

Once the last frost date has passed, and the soil temperature has reached around 60 degrees Fahrenheit, it is time to transplant your tomato seedlings to the garden. Choose a sunny, well-drained location, and amend the soil with organic matter, such as compost or aged manure. Transplant the seedlings deep into the soil, burying the stem up to the first set of leaves. Keep the soil moist, and provide support for the plants as they grow.

Direct Seeding Tomato Plants

If you prefer to skip the indoor seed starting process, you can also directly sow tomato seeds in the garden once the soil has warmed up. However, keep in mind that direct seeding may result in a later harvest, as the plants will need more time to mature before producing fruit. Plant the seeds about 1/4 to 1/2 inch deep in well-drained soil, in a sunny location. Keep the soil moist, and thin the seedlings once they have grown to about 2 to 3 inches tall.
