Tomato Seeds,
Dr. Wyche's Yellow

Start seeds indoors 6-10 weeks before the last expected frost date. Transplant seedlings outdoors when the soil is warm, and all frost danger has passed. Temperatures should stay consistently above 60 F. For precise timing, consult your local USDA zone frost dates. 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, maintaining soil temperatures between 70-80 F. A heat mat may be necessary to maintain consistent warmth for optimal germination, especially in cooler indoor environments. Once the seedlings emerge, provide them with plenty of light to prevent legginess. Transplant into the garden with 24 inches between plants for proper air circulation.

Dr. Wyche's Yellow tomato requires fertile soil enriched with compost or a balanced fertilizer. Regular pruning of lower leaves and suckers improves airflow and fruit production. Avoid overhead watering, focusing water delivery at the base of the plant to prevent fungal diseases. Monitor for pests and take action as needed to protect the plants.

• 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.
