How to Start Tomato Plants Indoors From Seed

Starting tomato plants indoors from seed is a great way to ensure a healthy and bountiful harvest. By starting the seeds indoors, you can control the growing conditions and get a head start on the growing season. Here are the steps to get started:

Gather Supplies

First, gather your supplies. You will need:

Tomato seeds

Seedling trays or small pots

Potting soil

Light source

Watering can

Make sure to choose a light source that is appropriate for growing plants. A grow light is ideal, but a sunny window will also work.

Prepare the Soil

Next, prepare the soil. Fill the seedling trays or small pots with potting soil, leaving about half an inch of space at the top. Water the soil thoroughly and allow it to drain.

Plant the Seeds

Plant the seeds according to the package instructions, typically around 1/4 inch deep. Cover the seeds lightly with soil and water gently. Keep the soil moist, but not soaked.

Provide Adequate Light

Once the seeds have sprouted, provide adequate light. If using a grow light, keep it 2-3 inches above the seedlings and on for 14-16 hours per day. If using a sunny window, make sure the seedlings receive at least 6-8 hours of sunlight per day.

Water and Fertilize

Water the seedlings as needed, keeping the soil moist but not waterlogged. Fertilize the seedlings once they have their first true leaves, using a balanced fertilizer according to the package instructions.

Harden Off and Transplant

Before transplanting the seedlings outdoors, they need to be hardened off to adjust to the outdoor conditions. Start by placing the seedlings outdoors in a sheltered location for a few hours per day, gradually increasing the time over the course of a week or two.

Once the seedlings are hardened off, they can be transplanted into the garden. Choose a sunny location with well-draining soil. Dig a hole slightly larger than the root ball and gently place the seedling in the hole. Don't bury the stem any deeper than it was in the original container. Water the plant thoroughly.

By following these steps, you can start tomato plants indoors from seed and enjoy a bountiful harvest of delicious, homegrown tomatoes.
