An incorrect cut won't kill the tree right away, but if it's pruned incorrectly or too often, it can. If a tree repeatedly loses too much of its crown at once, it may weaken or even die from stress. That's why you shouldn't cut more than 25% of a tree's crown at a time. You may be tempted to prune your trees heavily to provide more growth space for grass or other plants.
However, excessive pruning is very unhealthy and, in fact, can kill a plant. As a general rule, do not prune more than 15% of the foliage. If you must leave room for other plants, it's better to remove a tree completely than to risk over-pruning it. Pruning large tree branches, with diameters greater than 3 or 4 inches, can create wounds that are too large for the tree to close.
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. This way, the neck of the branch can seal the wound. Pruning cuts can stimulate new growths that, unfortunately, die when temperatures drop to zero. Trees and shrubs reduce their energy production as the growing season ends, so new growth in autumn will use the energy reserves stored in the plant.
The industry standard is to never make pruning cuts that remove more than 30 percent of a tree's living tissue at any time of the year. Some types of trees require special care when pruning to prevent diseases, pests and growth problems, so always research the specific requirements of your tree before pruning it. Since these trees have a lot of sun and less cold and adverse weather conditions, you can prune them all year round. Many believe that the best time of year to prune and prune trees is as soon as the shiny leaves start to fall.
Ask a local professional what time of year you should prune a sapling, as it can vary depending on the type of tree and the area of the country. Pruning a tree can improve its appearance, prevent pests and diseases, and help the tree grow strong and healthy. The tree will have a hard time healing in time for the cold season, which can lead to illness and deterioration inside the tree. Arbalists agree that the best time to prune trees is usually in winter, after the trees have been left dormant.
Pruning a tree is necessary to maintain its general health and structural integrity and to improve its aesthetic appeal. By getting rid of some of the dead, crossed and unwanted branches of a tree, you'll help improve the health of the tree and strengthen its roots by eliminating excess weight that can be a burden on the tree. At the end of the day, the right amount to prune a tree will also depend on the maturity of the tree and the reason for pruning. If you're ready to try pruning, here are a few different types of trees and the best time of year to prune each one.
Pruning fruit trees allows for an open canopy instead of a messy and overwhelmed canopy of branches that blocks sunlight from the rest of the tree. Keeping track of all your plants, when to prune shrubs, when to nail flowers and when to prune trees can be overwhelming on a to-do list.
