Start seeds indoors six weeks before last frost date.
Try to aim for a seed spacing of at least 0.78 inches (2.0 cm) and sow at a depth of around 0.78 inches (2.0 cm). Soil temperature should be kept higher than 12°C / 54°F to ensure good germination.By our calculations, you should look at sowing Brandywine true black about 42 days before your last frost date.
Plant to the first set of true leaves to promote strong root growth.
Ensure that temperatures are mild and all chance of frost has passed before planting out, as Brandywine true black is a tender plant.From Baker Creek Heirloom Seeds:
It was passed down to him from his Quaker grandfather’s collection dating back to the 1920s. As to its history, Will states "The “true” Black Brandywine was bred sometime in the late 1920s by Dr. Harold E. Martin (1888-1959), a dentist turned plant breeder who is best remembered today for his famous pole lima with huge seeds. Dr. Martin lived in Westtown, PA, only a few miles from my grandfather’s place in West Chester, and the two were gardening buddies. It was through that connection that his grandfather managed to wheedle seed out of the good doctor, as well as the details on how he created it. Dr. Martin always had a high opinion of his plant creations and did not like to share them–he charged 25 cents a seed for his lima, unheard of in those days. And he never released his Black Brandywine to a seed company, nor did he share it with many people, so I am fairly certain it never circulated among growers like his popular lima bean. According to my grandfather, Black Brandywine was a controlled cross between Brandywine and the original brown Beefsteak tomato otherwise known as Fejee Improved. Fejee Improved is probably extinct."
