Start seeds indoors 6-10 weeks before the last expected frost date. Transplant outdoors once the danger of frost has passed, and temperatures stay above 60 F, usually late spring to early summer. 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 seed-starting mix. During germination, keep the soil temperature between 70-80 F using a heat mat if necessary. Transplant seedlings after hardening off, spacing plants about 24 inches apart in rows spaced 3-4 feet apart for proper air circulation.

Mulch plants to retain moisture and suppress weeds. Regular pruning of suckers enhances airflow and directs the plant's energy toward fruit production. Fertilize every 2-4 weeks with a balanced or low-nitrogen fertilizer to encourage strong fruit development. Monitor for pests like aphids or caterpillars, and address issues promptly with organic controls.

• 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.
