Medium Blueberry - Northern Cultivars


The cultivated cultivars of the low blueberry (Vaccinium angustifolium) and the medium blueberry (V. angustifolium and V. corymbosum hybrids) come from the species growing in the forests of the north-eastern part of the United States and the south-western part of Canada. The Vaccinium angustifolium species is a small shrub with very tasty blueberries, 6 mm in diameter. Nowadays, they are still picked on a commercial scale in their natural habitat.
Both the low and medium blueberry requires similar soil conditions like high blueberry, i.e. regulated air and water conditions, sour soil and increased quantity of organic matter, however, it seems to be considerably more tolerant to higher pH and heavier soil. It is perfectly suitable for cultivation in small home and allotment gardens and in containers. On commercial plantations, thanks to dense planting, it yields a good crop. Its fruit, although slightly smaller, is as attractive and precious as the fruit of the high blueberry.
