Tomato Seeds,
Riesentraube

Start seeds indoors 6-8 weeks before the last frost date in your area. Transplant outside once the soil has warmed and all risk of frost has passed. We recommend that you refer to your area’s frost dates for specific 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 1/8 inch deep in seed trays and maintain a soil temperature of at least 70 F for germination, which takes about 7-14 days. Once seedlings develop true leaves, transplant them to individual pots, then harden them off before planting outdoors. Space plants about 24 inches apart in the garden.

Riesentraube tomatoes need regular watering and support from stakes or cages as they can grow to 6 feet tall. Fertilize every 2-3 weeks with a balanced fertilizer, and prune lower branches to improve airflow and reduce disease risk. Harvest when tomatoes are fully red and slightly firm.

• 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.
