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.
The most used and well known apple tree is the Orchard Apple tree (Malus domestica). There are about 30 to 55 species of apple trees (depending on which type of botanical taxonomic classification method used), of which most are small flowering deciduous trees and some grow as shrubs. Species of the Malus genus are commonly known as crabapples, crab apples, crabs, or wild apples.
