Tepary Bean IntroductionCultivation InstructionsSeed Saving Instructions
Cultivated in the Southwest for millenia, teparies mature quickly and are tolerant of the low desert heat, drought and alkaline soils.Plant seeds 1/2" deep and 4" apart with the summer rains. If rains are sparse, irrigate when plants look stressed. They do not tolerate overwatering. Teparies may carry bean mosaic virus, do not plant near other types of beans.A self-pollinating annual. Harvest pods as they dry. Be careful: mature pods will pop open and drop seeds if left on the plant. An alternative is to harvest the whole plants when pods are turning brown, allow them to dry on a sheet, then thresh and winnow seeds.
