Hi everyone. We have two apple trees in our property which were there when we purchased the home a couple years ago. We have really enjoyed the fresh fruits as well as preserving pie filling and apple sauce. I would like to plant several other varieties of fruit trees next fall- at this point considering cherry, pear, peaches, nectarines. We are in southwestern Pennsylvania in zone 5. I have been reading everything I can find online so that I know as much as I can before we plant next year. Can anyone recommend good books that would help me with choosing varieties best suited for my climate as well as providing details for planting and maintaining the trees? Thanks in advance. I love to spend the cold winters reading and planning for next year's garden.
