7 Tricks for Starting Tomato and Peppers Seeds Indoors

Dreaming of juicy, flavorful tomatoes and ripe, spicy peppers? Grow them yourself in only a few months.

If you’re as excited about tomato season as we are, why not get started now?

The best way to get a head start on growing tomatoes is to start seeds indoors 4-6 weeks before the last spring frost date in your region. Whether you’re growing cherry tomatoes or hot peppers, visit your local garden center to pick up supplies and seeds.

Here’s how to start tomato and pepper seeds indoors:

1. Test Seeds

If you saved tomato seeds from last year and stored the seeds properly, they should last for about four years. Pepper seeds will last about two to three years.

Check seeds for vitality before planting for a successful crop. Need seeds? Find them at your local garden center.

Test your seeds a few weeks before you’re ready to start. Place several seeds on a wet paper towel cover it with plastic and place it in a warm spot. If the seeds are viable, they should sprout within a week.

2. Soak Seeds

Give your seeds a head-start. Simply soak seeds in warm water for 2-4 hours to soften. Read the instructions on the seed packet to ensure the optimal conditions for your seeds.

3. Start Seeds

Gather supplies and fill seed trays to within ¼” of the top with Espoma’s Organic Seed Starting Mix. Follow instructions on the seed packets to see how deep and far apart to plant. Cover with soil, press down and lightly water.  Find out more about starting seeds here.

4. Add Heat

Once the seeds are planted, it’s time to warm them up. Heat loving crops like tomatoes and peppers love the warm weather. While your seedlings are sprouting, store them on top of the fridge or in a warm place. An even better option is use a special heating mat. The warm temperatures help to speed up the growing process. Make sure to check seeds daily for moisture since the soil may dry out more quickly.

5. Feed

Once the true leaves have developed, seeds will benefit from a nutrient boost. Add Espoma’s Organic Tomato! plant food to feed instantly.

6. Thin Plants

Thinning is the process of removing weaker seedlings to allow more room for the stronger ones. It creates healthier plants that produce more. As seedlings grow and you see crowding beginning to happen, gradually thin plants to 4” apart by gently pulling out the smallest ones with your hands.

7. Prepare for Transplant

Start hardening off plants once the last frost date has past. Place seedlings outdoors for seven to 10 days for a few hours each day. Once plants are ready for transplanting, gently remove plants from containers without damaging the roots. Plant in a prepared bed and mix in Espoma’s Bio-tone Starter Plus, to keep roots strong.  Once plants are established in the garden or container feed with Tomato! liquid or  Tomato-tone.
