Its not unheard of to get peaches the next year after planting, infact I've seen peach trees bloom and try to produce the the same year its planted, but you shouldn't letthathappen. The trees need time to grow and put their energy into a strong root system.

Apple and Pear trees, depending on variety take much longer, years really. On average 4 to 5 years, but you will possibly get an apple or two sooner. The apple and pear trees live much longer than peach trees and it takes longer for them to start producing. It will be 12 to 15 years before they produce bushels. And of course frost will be the ultimate factor then.
