Start seeds indoors 6-10 weeks before the last expected frost date. Transplant seedlings outdoors after the danger of frost has passed and soil temperatures have warmed. Check your local frost date calendars for precise planting times for your specific region. 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 quality seed-starting mix. Keep the soil temperature between 70-80 F during germination, using a heat mat if necessary. Harden off seedlings by gradually exposing them to outdoor conditions over 7-10 days before transplanting them into the garden. Space plants 24 inches apart in rows 3-4 feet apart.

Water consistently, keeping the soil evenly moist but not waterlogged. Applying a 2-inch layer of organic mulch helps retain moisture and regulate soil temperature. Fertilize with a balanced fertilizer or one formulated for tomatoes a few times throughout the growing season. Prune by removing suckers to direct energy toward fruit production and improve air circulation.

• 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.
