If a tree repeatedly loses too much of its canopy at one time, it can become weak or even die from the stress. That's why you shouldn't trim more than 25% of a tree's canopy at one time. Cutting the branch collar can also be a nasty error.
Others that are pruned too much may start to languish or die. Be patient. If the tree's branches weren't extremely weak or diseased, they should be able to initiate new growth. But, you probably won't see new blooms in the first, or even the second, year after a massive over pruning.
You should only remove 10 to 20 percent of the tree branches from the edge of the canopy. Large trees benefit from removing end portions of limbs between 1 to 4 inches in diameter. Small ornamental landscape trees and fruit trees can be thinned by removing smaller limbs between ¼ to ½ inch thick.
For a young tree, no more than 25% of the tree's live wood should be removed each year. For a mature tree, no more than 20% of the tree's live wood should be removed each year.
(Remember: leaves are how trees make their food.) Summer is also the most likely time for a drought to occur; a tree that is already stressed from over-pruning will be less resilient when water is scarce. Removing too many branches can also cause bark that has always been shaded to be exposed to the hot, fierce sun.
Heading cuts, particularly on large branches, are damaging both structurally and aesthetically. A heading cut chops off the end of a branch at an indiscriminate point, or at a branch junction that leaves only an undersized side branch growing in another direction.
Young Tree Snapped in Half, Will It Die? A tree breaking in half does not indicate that it will die since it is common for the growing plant to quickly develop roots and leaves to compensate for the lost nutrients. The foundation can get firmer, and the foliage will bloom faster to hasten the recovery process.
Although the accepted knowledge is that plants don't have neurons or brains, it's clear that even without nervous systems, trees on some level know what's happening and even feel something akin to pain: when one is cut, it sends out electrical signals and healing compounds — similar to wounded human tissue.
Without leaves, the cut tree cannot produce food for the growth of its roots. However, the roots might have enough nutrients left to allow the growth of sprouts from the roots or from the leftover stump. If a sprout develops enough leaves, it can eventually grow back into a tree.
One wrong cut won't immediately kill your tree, but pruning incorrectly or too often can. If a tree repeatedly loses too much of its canopy at one time, it can become weak or even die from the stress. That's why you shouldn't trim more than 25% of a tree's canopy at one time.
Trimming for tree health is often referred to as pruning, and it involves removing branches that are diseased, infested or interfering with healthy growth. Regular trimming keeps trees strong, creates a healthier structure and reduces the need for future corrective pruning.
In reality, pruning paint may impede healing and encourage the growth of rot organisms and insect infestation. Rather than seal out infection, wound dressings often seal in moisture and decay. In most cases, it is best to simply let wounds seal on their own.
ALWAYS prune back to or just above a growing point (branch or bud) or to the soil line. NEVER leave a stem or branch stub. NEVER top a tree to “rejuvenate” growth.
Not using the proper techniques can damage the health of your tree and can even lead to disease or premature death. In general, don't cut too close to the trunk. These cuts are too big and can delay the sealing of the wound. Don't cut too far from the surface of the trunk, either.
Proper pruning encourages strong growth, increases flower and fruit production, improves plant health, and removes damaged limbs, all which give aesthetic appeal to a tree. Pruning at the right time and in the right way is critical, since it is possible to kill a healthy tree through neglect or over-pruning.
If your tree has a less severe problem, one of the best times to remove trees is during the dormant season, between late winter and early spring. Here's why. Dormant trees are leafless and lighter, so it's much easier for a certified arborist to cut and handle the branches.
Wait till after the leaves fall. Mild fall weather may have you thinking about pruning shrubs and trees. But it's better to wait till late winter, or, at least, after leaves have fallen.
Differences Between Pruning and Trimming
Webb said pruning typically involves removing dead or diseased wood and thinning out stems and branches to improve the overall health and appearance of a plant. On the other hand, trimming typically involves cutting back plant material for reasons other than health concerns.
Tree Pruning Encourages Tree Growth and Structure
Maintaining the tree's structure helps to mitigate the risk of broken limbs and falling branches. A properly pruned tree will not have compromising branch structures and improper weight distribution that could lead to disaster later on in the tree's life.
Can tree branches grow back? When pruned properly, removed tree branches will not grow back. Instead, the tree will grow what looks like a callous over the pruning cut, which helps protect the tree from decay and infection. Because trees heal all on their own, you don't have to use a pruning sealer!

Prune as little as possible.
Prune only as much as you absolutely need to prune, and never remove more than 25 percent of a tree's branches. For most deciduous trees, make sure that there are living branches on at least 2/3 of the tree, though this varies by species.
