Medicine is not for everyone. Choosing to pursue a career in medicine for prestige or financial rewards will likely be disappointing, as most physicians find that medicine is a vocation that requires a commitment to service, lifelong learning and the dedication to practice competently and compassionately.
Though in many European orchards the number of trees per acre is set at 5,000 trees or more, in the US the apple tree density starts at 450-485 trees per acre with a maximum of 1,100 trees/acre. This is a recommended number for the dwarf apple trees.
Early production is directly related to the number of trees planted per acre. The greater the tree number, the greater the light interception by that acre of land early in the life of the orchard. To the extreme, there are orchards planted in Europe and the Pacific Northwest with 5,000-9,000 trees per acre.
