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.
Apple trees need at least 8 hours of sun per day during the growing season. Plant trees 6 to 20 feet apart - the lower end of the scale for dwarf trees, more for semi-dwarf, and the most for standard size trees. Two cultivars are required for successful pollination. One can be a crab apple.
