pruning apple trees

[rodsauder]

The property I purchased last fall has a an old orchard. The trees are really overgrown, i am looking for any and all advice here on pruning. I assume now is the correct time of year? How much should I take off at one cropping ? approx 30% more ? Less? looking for tips, comments, etc. Thanks

I'm no expert and only have 7 trees. However, if you do a google search there are some great references out there. Some state extension schools have great websites on how to trim fruit trees. Good luck!

This is always the source of my most premium fire wood.

I was once told, how severly orchards apparently prune their trees.

Remove anything dead then work on getting it back to a scaffold shape. You may want to put some lime down for calcium after you do a heavy prune. Watch there will be water spouts everywhere.

has a lot of articles and you tube videos.
I have been working on my apple trees for years it takes patience.

several youtube videos of tree pruning.

Good rule of thumb is no more than 30% of the tree, start with the suckers (long straight bows, that shoot straight up).
Remember that apples will grow on wood produced the previous year, so always leave a good proportion (say 50%) of the previous year's growth(evident with a knuckle spur and a small branch containing a few leaves, typically about 2" in length). Its also a good time to prune back the branches near last years buds in an effort to have the limb go in the direction that will open the inner canopy for as much sunlight as you can get. I prune the buds in an effort to keep the limbs horizontal with as little vertical growth as possible, but beware, low limbs will sag with a heavy fruit concentration, limiting mower access in the late summer and early fall. The benefit is you don't have to reach far from your seat to grab an apple as you mow!

I was researching the same thing, sorta. More for 3 year old trees, but I read several articles online about "re-starting" old apple tees, Just go on Google and search. I would provide a link, but cant remember where it was (I think Ohio state) I did read that rehabbing older trees is a bit different than trees that have been maintained.

I prune my almond trees (about 24 of them) in January just before they break dormancy. I just remove the low hanging branches so I can mow the orchard in the Spring. Like your apple trees, my almonds are probably 80 years old and way overgrown. I don't bother pruning the high branches. These trees still produce a lot of sweet almonds. The blackbirds do the harvesting for me.

There are thousands of acres of orchards around here (almonds, plums for prunes, English walnut, olives, mandarin oranges, pistachio). The almonds and plums are pruned by just giving the trees the flat top treatment to remove the previous year's growth and keep the trees short enough to handle with the harvesting equipment. Any low hanging branches are pruned by hand. These orchards are kept scrupulously clean, no rotting fruit on the ground, and mowed with flail mowers to prevent disease problems.

Good luck.

We've been in full swing pruning the apple trees at the orchard for many weeks now obviously we have a lot of them to get done. But anytime late winter early spring while the tree is still dormant is the correct time. If you have a really overgrown old tree with lot of bad wood might have cut it back hard close to the main trunk to get started again. With no leaves on them the older trees can and do look pretty odd. Main trunk with 2 or 3 large leaders then smaller leaders spreading out and up then your spur limbs coming off of them. We fertilize every fall with a ring of low nitrogen fertilizer usually just a 5 10 10 blend spread out around the dripline of the tree. Calcium application are good too do too. To get really large apples we thin the trees leaving only a few otherwise a lot of heavy fruit set will generally produce small apples. It's done by spraying chemicals that cause fruit drop in most conventional commercial operations nowadays but for years it was also done by hand labor and sometimes still is

There are many university links and online videos. Here's one from the University of Maine Cooperative Extension.

The University of Maine - Cooperative Extension Publications - Bulletin #2409, Renovating Old Apple Trees


MOFGA is running a hands on workshops during March on pruning and renovating apple trees for anyone in their vicinity.

Thanks for all of that. I will post a picture of a few trees, before and after. I think I will basically remove any dead limbs, then a few of the shooters that go straight up and finish by making sure I can mow around the bottom. I am going to try going fairly severe on a few trees and easy on a few others. It should be interesting to see the results. Thanks everyone for the input.
