Prune only as much as is absolutely necessary for pruning and never remove more than 25 percent of a tree's branches. Keep in mind that the trunk alone is not enough to ensure that the tree survives. In general, saplings should only have about 25 percent of their foliage pruned each growing season. If the tree is in the right place, with fertile soil, these vigorously growing trees have enough energy and strength to withstand this type of canopy pruning.
Pruning helps control the maximum size of the tree and trains it to grow strong on branches of fruit trees that contain heavy fruit. Trimming the canopy allows light to descend through the crown to the lower extremities. This increases photosynthesis in the lower parts of the tree and encourages fruit trees to produce more. Extendable mast saw with chain drive & (7 ft to 16 ft) When thinning, reducing and shaping branches and limbs small enough to be cut with hand tools, keep in mind that your cuts will encourage new growth.
With that in mind, cut the branches ¼ inch above a bud that faces the outside of the plant. This will be the direction of the new growth. Keep the incisions at a 45-degree angle to prevent damage and illness caused by water. Move approximately 18 inches down the bottom of the branch you are removing.
This is the perfect spot for your first incision. Cut approximately halfway through the branch. Since the goal is not to change the size or shape of the tree, the thinning must be constant throughout the tree. You should only remove 10 to 20 percent of the tree branches from the edge of the canopy.
Large trees benefit by removing the end parts of branches that are between 1 and 4 inches in diameter. Small ornamental landscape trees and fruit trees can be thinned by removing smaller branches that are between ¼ and ½ inch thick. You should prune the trees to thin the crown, so that the tree still looks completely unpruned. The 3-cut pruning method ensures that larger branches are cut cleanly, without breaking the bark.
Trees may also need to be pruned and therefore reduced in size if they have dead, sick, crossed, or broken branches. Leaving only a small branch at the end of a large branch that is cut is aesthetically unattractive and risks the small branch growing out of an unstable branch stem. This occurs when a branch is cut flush with the bark of the tree trunk or a larger branch to which it is attached. Depending on the crown of the tree and its branch structure, it is best to remove a large diameter branch by cutting it to the trunk.
Instead, depending on the tree species, an experienced pruner will select a solid side branch along the trunk and make a proper pruning cut just above it. The first two cuts eliminate the weight of the tree branch and the final cut is designed for the best growth of calluses. Pruning cuts can stimulate new growths that, unfortunately, will die as temperatures drop to zero. When thinning, reducing and shaping branches and limbs small enough to be cut with hand tools, keep in mind that the cuts will stimulate new growth.
Most tree branches that are cut to the trunk or a main branch will require three cuts to avoid damaging the bark. The mass of thin branches that sprout from cut branches not only looks bad, but is also prone to breakage and will require more frequent pruning to keep them under control. This winter, during the dormant season, cut them into 3-4 scaffold branches that extend to form a full canopy. Because the plant cannot close the wound, a flush cut leaves an opening for pests and pathogens to enter the plant and damage or kill it.
If you've ever seen a cut forsythia or a tree in the crown, then you'll know that cuts on the head generally don't work well. A head cut cuts the end of a branch at an indiscriminate point, or at a junction of branches that leaves only an undersized side branch growing in another direction. If you make a pruning cut on an indiscriminate branch, it will stimulate the growth of many small branches around the wound that are not strongly attached and do not follow the natural growth of the branches. Usually, that's because they made the common pruning mistake of cutting the branch with a single cut.
