CHERRIES - SWEET OR SOUR
Sweet cherries have similar location requirements to apple trees. They grow well on nutrient-rich, well drained, and moist (but not waterlogged) soils. Areas with late frosts must be avoided because of the risks associated with early flowering. In areas with high precipitation, a polythene cover is recommended due to the high risk of fruit bursting. Most varieties are self-infertile and need pollinators. They are usually harvested mechanically. Sour cherries have less stringent location requirements compared to sweet cherries. However, cold and impermeable soil can cause premature fruit fall. The risk of bursting is reduced, making them also suitable for areas with plenty of summer precipitation. Sour cherries are usually self-pollinating. Since sour cherry trees are mainly grown for processing, they are usually harvested mechanically.
