I have heard that pruning fruit (apple, pear, etc.) trees is different from pruning regular trees like Maple and Oak. Is this correct and can you give me tips on pruning fruit trees.

Thanks,
Michael

Fruit trees are pruned to encourage fruit, which differs from pruning for shape in ornamental trees. The "Modified Leader" method is probably the best route for a home grown apple tree. It starts out with one leader, but as that central trunk becomes stronger it is allowed to form several tops. This helps the tree sustain the weight of the fruit. Eventually, you'll want to shorten the tree a bit, which will make it easier to pick the apples as well as allow sunlight and air to get into the central part of the tree.

As far as when to prune, I would suggest waiting until the very coldest part of the winter is behind you, but the weather is not warm yet. It's a time you're anxious to get into the garden and there are many pleasant days when it's fun to do this. The tree will still be dormant with no leaves, so it's a good time to be able to stand back and make a good judgment about just what needs to go or stay.

When you prune, the first thing you do is remove damaged, broken and diseased branches. Next, remove any branches that rub or touch each other. When that is done, stand back and STUDY from all angles. Then carry out the suggestions above for the 'modified leader' method.

If you do a fair amount of pruning it will produce a big, flush of growth in the spring, therefore be on the lookout for suckers and water sprouts (vigorous vertical shoots) and take them out when they appear. When you cut, cut quite close to the nearest branch or trunk leaving just barely a "neck". Do not leave stumps as they will be a weak point on the tree and invite disease and insects. Remember that pruning off too much at any given time will probably stress your tree. So don't go "overboard".

Here is the web site for The Virtual Orchard "http://orchard.uvm.edu". There might be some additional information there which would be of help.
