Tomato Seeds,
Alice's Dream

Start seeds indoors 6-10 weeks before the last expected frost. Transplant outdoors only after the threat of frost has passed and temperatures stay above 60 F. Check your region's last frost date for precise timing. 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 indoors in a seed-starting mix, planting them 1/8 inch deep. Maintain soil temperature at 70-80 F, using a heat mat if necessary. Harden off seedlings before transplanting outdoors. Space plants 24 inches apart and use stakes or cages to support the plants as they grow.

Use fertile, well-draining soil rich in organic matter and amend it with compost before planting. Keep the soil consistently moist but avoid waterlogging. Feed plants with a balanced fertilizer or tomato-specific feed every few weeks. Remove suckers to encourage better air circulation and fruit production.

• 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.
