Sometimes a tree just gets too big for its britches…or it hasn’t been cared for properly over the years…or perhaps some big branches have fallen victim to disease. This is where reduction pruning comes into play. This technique restores balance to a deciduous tree’s shape and reduces its size.

In cases where severe pruning is needed, it’s a good idea to spread the pruning over two seasons.
You should wait to perform reduction pruning in fall – after all the leaves are off the tree and it’s dormant. Be sure to water faithfully the following season to keep your tree strong and encourage good health.
For step-by-step guidance, gather your long-handled pruners, plastic tape, a pole pruner, pruning saw, a tree ladder, gloves and protective eye goggles.
Then just follow the steps shown in these pictures and described in their captions.
If you prune correctly, your tree will look so good, passersby will hardly be able to tell it’s had its crown reduced. 주의 : topping, pollarding 이 되지 않도록
Reduction Pruning
Reduction Pruning - Step 1
Remove any dead, weak or crossing branches,
trimming them flush with the trunk.
Reduction Pruning - Step 2
Evaluate the next cuts you’ll make by marking them with plastic tape.
These cuts should reduce the canopy size by 25-33 percent and be symmetrical.
Reduction Pruning - Step 3
Use a pole pruner to remove all small foliage branches outside of the main cut markers, leaving bare branches.
Reduction Pruning - Step 4
Use a pruning saw to remove branches with three cuts: the first cut halfway and underneath, followed by a second cut halfway from above and outside the first cut. Finally, cut the stub off at the crotch with the trunk.
Reduction Pruning - Step 5
Select 3-5 laterals from each main branch for retention,
then remove the remainder.
