Description

(Solanum lycopersicum). A Russian heirloom with a silky texture and a smoky, complex flavor. Black tomatoes are famous for their rich, nuanced flavor, and the 7-ounce, globe-shaped fruit of Brown Sugar does not disappoint. This is a gourmet, sugar-sweet tomato, just perfect for snacking, slicing, cooked dishes, and sauces.

Growing Tips: Brown Sugar tomatoes grow best in well-draining, nutrient-rich soil with a slightly acidic pH of 6.0 to 6.8. Make sure the plants get 6-8 hours of full sunlight daily. Consistent watering is also important, keeping the soil evenly moist while allowing the top layer to dry slightly between watering to avoid diseases like blossom-end rot or fruit cracking.

When to Grow

Start seeds indoors 6-10 weeks before the last frost date. Once all danger of frost has passed, and the soil has warmed, you can transplant the seedlings outdoors. Check your USDA zone's frost dates 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."

How to Sow and Plant

Sow seeds 1/8 inch deep in a seed-starting mix. Maintain a soil temperature of 70-80 F for optimal germination. You can use a heat mat to speed up the process. Before transplanting into the garden, harden off seedlings by gradually exposing them to outdoor conditions over a week. Space plants 24 inches apart for good airflow.

How to Grow

As an indeterminate variety, Brown Sugar tomatoes will need support such as staking, caging, or trellising. Prune the plants regularly by removing suckers (small shoots between the main stem and branches) to enhance air circulation and focus the plant's energy on fruit production. Fertilize with a balanced tomato fertilizer during planting and side-dress with compost or organic fertilizer every 3-4 weeks throughout the growing season.

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.
