Tomato Seeds,

Start seeds indoors 6-10 weeks before the last expected frost date. Transplant seedlings outdoors only after the danger of frost has passed and temperatures don’t drop below 60 F. If you’re not sure how to find your first and last frost dates, consult our blog post "Our Experts Answer Questions, Share Resources."

Sow seeds 1/8 inch deep in a seed-starting mix. During germination, keep the soil temperature between 70-80 F. Use a heat mat for it if necessary. Once seedlings have two sets of true leaves, harden them off and space 24 inches apart. When planting, bury two-thirds of the seedling, including the lower leaves, to encourage robust root development.

Apply a balanced fertilizer at planting time and side-dress the plants with compost or additional fertilizer every few weeks during the growing season. Prune the plants to focus energy on fruit production. Mulching with organic material around the base of the plants conserves moisture, regulates soil temperature, and suppresses weeds.

• Most tomatoes are self-pollinating and don't frequently cross; in a garden setting, separating by 25 feet should prevent 99% of cross-pollination. Or you can bag and hand pollinate for 100% purity.
• On a small scale, seeds may be scooped from the fruits and dried on a paper towel.
• For larger quantities or cleaner seeds, fermentation for a few days is recommended.
• Once dry, tomato seed can be stored in a cool, dry, dark place; good seed retains viability for 5 years or more.
