Description

(Solanum lycopersicum). Potato leaf. This fine variety was sent to us by our friend, famed seed collector and food writer William Woys Weaver of Pennsylvania. It was passed down to him from his Quaker grandfather’s collection dating back to the 1920s. We thank Will for entrusting us with this great-tasting tomato that is extra large in size and full of the deep, earthy, and sweet flavor that has made blackish-purple tomatoes so popular. Superior for salsa and cooking. We enjoyed these all summer, both fresh and in countless recipes. A great home garden variety that will surely become a favorite.

Growing Tips, Tricks and FAQs

Growing Tips

True Black Brandywine tomatoes thrive in well-drained, nutrient-rich soil with a slightly acidic pH (6.0–6.8). Amending the soil with compost or well-rotted manure enhances fertility. Plant in a location that receives 6–8 hours of full sunlight daily. Use strong stakes or cages to support the plants, as the fruits can be large and heavy.

When to Grow

Start seeds indoors 6–10 weeks before the last frost date in your area. Transplant seedlings outdoors once temperatures consistently stay above 60 F. True Black Brandywine tomatoes need quite a long growing season, maturing in 80-90 days after transplanting. Check your local area’s frost dates to time planting accurately.

How to Sow and Plant

Sow seeds 1/8 inch deep in a nutrient-rich, well-draining seed-starting mix. Keep the soil temperature between 70-80 F for optimal germination. Seeds should germinate in 7–14 days. When seedlings develop two sets of true leaves, transplant them to larger pots or outdoors once frost risks have passed. Space plants about 24 inches apart, and water thoroughly after planting to establish roots.

How to Grow

Consistent watering is very important, so provide about 1–2 inches of water per week. Water at the base of the plant to prevent wet foliage, reducing the risk of fungal diseases. Apply a balanced fertilizer or compost at planting and side-dress with additional fertilizer when flowers begin forming. Prune suckers to focus the plant's energy on fruit development and prevent overcrowding. Mulch around the base of plants to retain moisture and regulate soil temperature.

How to Save

  • 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, and good seed retains viability for 5 years or more.
