Cultivation details

A very easily grown plant, it prefers dry sandy soils but succeeds in most conditions including poor, heavy or acid soils[160] and even sub-soils. Prefers a cool moist climate, also succeeds in dry and arid regions. Tartarian buckwheat is hardier and more resistant to cold than the more commonly grown buckwheat, F. esculentum, though it does not yield so highly[132]. Occasionally cultivated for its edible seed in Europe and the Himalayas[50, 51], there is at least one named variety[183]. 'Madawaska' is more cold hardy and drought tolerant than the type[183].
