Apple trees may function differently depending on how they are grown. In colder regions of North America, berry fruits require a shorter annual period of warmth to allow flowering and fruiting, so if an orchard uses a longer winter dormancy period this will delay orchard maturation. In areas with milder winters such as California many varieties of apples flower and produce fruit two years after planting- nevertheless some growers believe that these varieties require three years for optimal production of high quality fruit crops…
