Growing tomatoes from seeds saved from your own old tomatoes is an easy and rewarding way to keep your garden thriving year after year. Here’s a simple guide to help you get started.
Step 1: Choose a Ripe Tomato
Pick a fully ripe tomato from your harvest or the market. The seeds inside mature best when the tomato is completely ripe.
Step 2: Extract the Seeds
Cut the tomato open and scoop out the seeds along with the surrounding gel into a small container.
Step 3: Ferment the Seeds
To remove the gel coating that inhibits germination, let the seeds sit in the container with a little water for 2 to 3 days at room temperature. Stir daily. You’ll notice a layer of mold or foam forming on top—this is normal and helps separate the seeds.
Step 4: Rinse and Dry the Seeds
After fermentation, rinse the seeds thoroughly under running water to remove the gel and mold. Spread the seeds out on a paper towel or plate to dry completely, which can take a few days.
Step 5: Plant Your Seeds
Once dry, plant the seeds in seed-starting soil about ¼ inch deep. Keep the soil moist and place the container in a warm, sunny spot. Tomato seeds usually sprout within 5 to 10 days.
Final Tips
- Label your seeds if you’re saving different tomato varieties.
- Start seeds indoors 6 to 8 weeks before the last expected frost for best results.
- Transplant seedlings outdoors after the danger of frost has passed and the plants are strong enough.
By saving and planting seeds from old tomatoes, you can enjoy homegrown tomatoes year after year while connecting with the natural cycle of growth and renewal. Happy gardening!
