Tomato Seeds,
Brandywine Sudduth's Strain

Start seeds indoors 6-10 weeks before your region's last frost date. Transplant outdoors once all danger of frost has passed and temperatures stay above 60 F. Check your local area’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."

Sow seeds 1/8 inch deep in seed trays filled with seed-starting mix. Maintain a temperature of 70-80 F for optimal germination, use a heat mat if necessary. Harden off seedlings for 7-10 days before transplanting them outdoors, spacing them 24 inches apart.

Water deeply and regularly to ensure consistent soil moisture. Mulch around the base to conserve water and suppress weeds. Prune suckers and lower leaves to improve airflow and focus the plant’s energy on 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.
