　　What could be simpler than shaking fruit from a tree? Well, the job is a lot more difficult than you might think. There is a right way and a wrong way to shake a fruit tree. And a person who is a good apple tree shaker may not he a good cherry tree shaker. Different fruits take different shakes.

　　As a rule, a slow hard shake is best .This makes the fruit fall much faster than a light, quick jiggle. Most fruits have a set number of shakes per minute that will do the best job of getting them out of the tree and onto the ground . To shake down plums, try shaking the tree four hundred times per minute, moving the tree two inches at each shake. Experts say you'll get three times more fruit from the tree than you will if you shake eleven hundred times per minute at one inch per shake. Cherries, because they are smaller, need more shaking. A good rate of shaking seems to be about twelve hundred shakes per minute. Apples, like plums, need four hundred shakes.
