High bush blueberries grow well in impoverished acid soils (ideally pH 4.3-4.8, although they can tolerate slightly higher pH if dressed with peat) of the type which underlie many of the heathlands of Britain. The ground is cleared and the bushes planted at an appropriate density. Their only major nutrient requirement is potash, but to do well they do need heath-land environments, as good growth relies on the presence of a particular micro-organism in the soil, which is not found in land that has been cultivated. They are pruned lightly in winter to remove old wood which has not fruited in the previous season. Protection from birds is necessary.
