How to Plant Tomato Seeds from a Tomato: A Step-by-Step Guide to Growing Your Own Tomatoes

Have you ever thought about planting your own tomatoes after enjoying a juicy one? If you’ve ever wondered how to do it, you’re in the right place! Planting tomato seeds from a tomato, whether it’s from your garden or a store-bought one, is a rewarding and enjoyable process that can lead to a bountiful harvest. Don’t worry, I’ve got you covered with simple steps to help you grow your own delicious tomatoes.


Step 1: Pick the Right Tomato

The first thing you’ll need is a good tomato. It’s essential to use one that’s ripe and healthy—look for one that’s firm, plump, and free from any blemishes or mold. If you’re using a tomato from your own garden, that’s even better! You know where it’s been. Store-bought tomatoes work too, but just ensure they’re fully ripe.


Step 2: Extracting the Seeds

Next up, you’ll need to extract the seeds. Here’s a simple method to do this:

  1. Slice the Tomato – Cut the tomato in half horizontally to expose the seeds.
  2. Scoop the Seeds Out – Using a spoon or your fingers, gently scoop out the seeds and any jelly-like pulp that surrounds them. Don’t worry if some pulp clings to the seeds—it’s part of the process.
  3. Soak in Water – Drop the seeds and pulp into a small bowl of water and leave them to sit for a couple of days. This fermentation process helps break down the pulp, making it easier to separate the seeds later on. After a few days, the seeds will sink to the bottom of the bowl, and the pulp will float to the top. Skim off the pulp and rinse the seeds.

Step 3: Drying the Seeds

Once your seeds are clean, the next step is to dry them. Lay them out on a paper towel, plate, or tray. Leave them in a warm, dry spot for about 3-5 days until they’re completely dry. Make sure they’re fully dry before storing them to avoid mold or rot.


Step 4: Store the Seeds

Now that your seeds are dry, store them for later use. The best way is to place them in a labeled paper envelope, noting the variety and year of harvest. Keep the envelope in a cool, dark place like a drawer or cupboard until you’re ready to plant. With proper storage, tomato seeds can last for a few years.


Step 5: Planting the Seeds

When the time comes to plant your seeds, which is typically about 6-8 weeks before the last frost date, it’s time to start. Here’s how to do it:

  1. Prepare Your Seed Tray – Fill a seed tray or small pots with seed-starting mix. This soil is light and drains well, which is perfect for seedlings.
  2. Plant the Seeds – Create small holes about 1/4 inch deep and place one seed in each hole. Cover the seeds gently with soil and water lightly.
  3. Provide Warmth and Light – Tomato seeds need warmth to germinate. Keep them in a warm spot, ideally between 70°F to 80°F (21°C to 27°C). They also need plenty of light. Either place the tray near a sunny window or use grow lights.
  4. Watering – Keep the soil moist, but not soggy. Once the seeds begin to sprout, you’ll see tiny green stems. At this point, water a little less frequently, allowing the soil to dry out between waterings.

Step 6: Transplanting Your Seedlings

Once your seedlings have grown a few inches tall and have at least two sets of leaves, it’s time to transplant them outdoors (or into larger pots if you’re growing them in containers). Wait until after the last frost date, and before transplanting, acclimate the plants to outdoor conditions by hardening them off for a few days.

Plant the seedlings in nutrient-rich, well-draining soil with plenty of sunlight. Leave about 18-24 inches of space between each plant, depending on the variety, so they can grow freely.


Bonus Tips for Growing Healthy Tomatoes

  • Germination Time – Tomato seeds typically take between 5 and 10 days to sprout, but it could take a little longer. Patience is key!
  • Pruning – As your tomato plants grow, you may notice small shoots, known as suckers, developing between the main stem and branches. Pinch these off to help the plant direct its energy to fruit production.
  • Fertilizing – Once your plants are in the ground, feed them with a balanced fertilizer every few weeks to promote healthy growth.
