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.
When you order your new apple tree, you will choose which size you want it to be at maturity: a dwarf (8-10 feet tall and wide), a semi-dwarf (12-15 feet tall and wide), or the occasional standard (18-25+ feet tall and wide). Be careful to choose the size best suited to your needs and available space.
