Weaver’s Black Brandywine Slicing Tomato

Also Available As

seeds

Solanum lycopersicum
(85 days) Open pollinated.

Indeterminate with potato-leaf foliage. Also known as True Black Brandywine. Not the only attempt at pairing the smoky depth of “black” tomatoes with the full tart and sweet balance of Pink Brandywine, but Weaver’s Black could be the oldest and is likely the best flavored.

Bred by Dr. Harold Martin in late 1920s in Pennsylvania, its irregular flattened large heirloom beefsteak shape looks coal dusted over crimson, with shadows of green, purple and brown. Winner of our 2016 taste trial of dusky types, Weaver’s flavor intensity of peaty whiskey and rich tomato is not for the faint of heart, and everyone who tries it will have an opinion.

Given safe harbor by William Woys Weaver’s Roughwood Seed Collection since being kept by his grandfather. The usual delicate handling and quick consumption rules of cherished heirloom tomatoes apply.

Additional Information

Tomatoes

Days to maturity are from date of transplanting

Culture: Usually started indoors Feb–April. Minimum germination soil temperature 60°, optimal range 75–90°. Transplant after frost danger has passed. Avoid using fresh manure as it causes lush foliage with few ripe fruits. Instead use generous amounts of well-rotted cow or horse manure or compost to boost plant vigor, and crushed eggshells or gypsum at the bottom of each hole for calcium. Heavy phosphorus needs. Responds well to foliar sprays.

Determinate (Det.) bush varieties may be staked, should not be pruned.
Indeterminate (Ind.) climbing varieties are customarily staked and pruned. Tomato experts Carolyn Male and Kokopelli’s Dominique Guillet both oppose pruning, arguing more abundant foliage provides more photosynthesis.

Organically and sustainably grown seed was rinsed with a sodium hypochlorite solution to reduce risk of seed-borne disease. This treatment poses no health risks.

Saving Seed: Saving tomato seed is easy! Remove stem-end and crush the fully ripe fruit into a container. Ferment uncovered for a few days until the slurry forms a moldy cap. Rinse in a fine strainer and dry seeds on a coffee filter. To ensure true-to-type seed, grow open-pollinated varieties and separate by 50 feet.

Diseases:

ASC: Alternaria Stem Canker
EB: Early Blight

LB: Late Blight
N: Nematodes
SEPT: Septoria Leaf Spot
TSWV: Tomato Spotted Wilt Virus
TMV: Tobacco Mosaic Virus
V: Verticillium

Pests and Disease Remedies for Tomatoes

Early Blight shows up as drying and dying leaves at the bottom of the plant. EB can be managed culturally; should not result in significant crop loss. Mulching deters EB by reducing rain splash on foliage. Do not compost affected plants as EB can overwinter even on dead tissue.
Cultural controls: Rotation, avoid stressing plants, staking, minimize leaf wetness, mulching, indeterminate varieties are more resistant/tolerant, disinfect stakes & cages.
Material controls: Regalia, Cease.

Late Blight usually starts on the foliage of the plant. Early in the season, late blight infection shows as roundish lesions on leaves that uniquely will cross the center vein of the leaf. Later, blotches appear on stems. Still later, hard crusty lesions form on fruits. LB on tomatoes is not seed-borne and does not survive on dead tissue. Letting plants freeze on soil surface kills LB spores.
Cultural controls: Destroy cull potatoes & potato volunteers, avoid overhead irrigation.
Material controls: Regalia, Copper, Cease.

Septoria Leaf Spot can appear almost overnight. It is characterized by yellowing and small circular spots on older leaves. It can eventually spread to the entire plant in conditions of high humidity and temperatures. It can be spread by wind or carried on clothing and tools. Septoria can live over the winter on live tissue, so don't compost affected plants.
Cultural controls: Space plants for good air circulation.
Material controls: Regalia, Copper, MilStop.

Anthracnose
Cultural controls: Rotation, mulching, minimize plant wetness, staking, use compost.
Material controls: MilStop, Copper, Regalia, Cease

Tomato Hornworm
Cultural controls: Look for frass (droppings) and handpick. Eeeuww! Use a blacklight to find them. See if you can get the chickens to eat them.
Material controls: Bacillus thuringiensis subsp.kurstaki, Monterey Garden Insect Spray.

Tarnished Plant Bug
Cultural controls: Floating row covers, good weed control.
Material Controls: Pyrethrin.

Bacterial Canker, Spec and Spot
Cultural controls: Disinfect greenhouse materials & cages, farming tools & gloves, avoid overhead irrigation, don’t work crop when wet, rotate crops, use compost.
Material controls: Copper.

Preventing Late Blight

Dry conditions spare us some years, but late blight is here to stay, especially for field-grown crops. Cool temperatures, moist conditions, still air and lack of sunshine favor sporulation; spores can occur and advance in any condition of high humidity. LB might spread quickly... or not; wind-borne spores can travel hundreds of miles on storm fronts, but also can be baked into submission by the hot sun. Once LB lesions develop on your plants take immediate action to halt the disease in hopes of salvaging a crop. Our recommendations:

Where possible, use resistant varieties.
Try to find tolerant cultivars—use anecdotal evidence and experiment.
Grow your own tomato plants or buy locally grown seedlings. Avoid big-box seedlings. Know your farmer!
Do not use saved potatoes as seed stock. Purchase only new certified disease-free seed potatoes. Click here for more potato-related late blight info.
Plant in areas with full sun and few wind blocks. Avoid shade and moist environments. Facilitate air movement. Maintain high soil fertility.
If you choose to spray, have a plan and materials on hand, so you can make quick and timely application(s) when conditions indicate. Order supplies from Organic Growers Supply
Most market growers and many home gardeners now grow at least a portion of their tomatoes in high tunnels, which greatly reduces vulnerability though still requires vigilance.
