Growing Guide

When to Grow

Start seeds indoors 6-10 weeks before the last expected frost. Transplant outdoors after frost danger has passed and temperatures stay above 60 F. Check your local region’s frost dates to determine a specific planting time. If you’re not sure how to find your first and last frost dates, consult our blog post "Our Experts Answer Questions, Share Resources."

How to Sow and Plant

Sow seeds 1/8 inch deep in seed-starting mix, maintaining soil temperatures of 70-80 F for optimal germination. Harden off seedlings over a week by gradually exposing them to outdoor conditions. Space plants 24 inches apart.

How to Grow

Water plants at the base, providing 1-2 inches of water weekly. Fertilize with a balanced or tomato-specific fertilizer every 4-6 weeks. Prune suckers to promote airflow and focus energy on fruit production. Apply mulch to conserve soil moisture and suppress weeds.

How to Save Seeds

  • 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.
