DO MY TREES NEED TO BE TRIMMED?
Tree trimming is the commonly performed procedure of removing unwanted limbs from a tree. Here are some signs that your trees may need to be trimmed
WHEN AND WHAT TO CUT
Keep in mind that you should only remove 30% of a tree's canopy in a year; removing more than this could harm the tree. Also remember that trees handle a heavy trimming better if it is done while the tree is dormant; this period is usually late fall to early spring.
DON'T HURT THE TREES YOU LOVE
While most tree trimming is relatively simple, more harm than good can be done to your tree if you:
Dead wooding is simply removing all the major dead from a tree. Dead wood in a tree is harmful as it:
Note that a small amount of deadwood is normal in any given tree. However, a large amount of deadwood can indicate other problems with your tree. In this case, your tree is probably dying and will need to be removed unless it can be treated.
Pruning is essential to maintaining the health of your trees. Generally speaking, pruning involves removing dying, dead, and diseased limbs. Next, any crossing or rubbing limbs should be looked and the weaker limb should be removed. Finally, any suckers at the base of the tree should be removed.
For flowering plants and fruit bearing trees, further guidelines should be addressed that are specific to the species.
When pruning or dead wooding trees, be careful not to remove all the inner foliage. The inner foliage perform photosynthesis during the hottest times of the day while the exterior leaves perform photosynthesis during the cooler times of the day. Many tree services will "clean out" a tree of its inner foliage, but this leaves a homeowner with a tree that is more susceptible to a hot dry summer.
Trimming is performed to change the shape of a tree, while pruning is usually enhances the health of a tree.
A small amount of deadwood is normal in a tree due to limbs losing their access to sunlight when other limbs grow above them. However, when a large section of your tree dies, this usually indicates that your trees have other problems. If your tree has deadwood that doesn't look normal, you will need to contact an arborist to assess your trees health and provide a remedy for it.
Light trimming and pruning can usually be done at any time of the year, but it is best for the health of the tree to do heavier trimming and pruning in late fall and winter.
The answer to this question is very situation specific and cannot be answered without an in-person consultation. However, here are general guidelines that should be followed:
Generally speaking, limbs can be raised by strategically pruning off down hanging limbs and strategically shortening the limbs total length. However, a limb will only raise up so much, and the whole limb might need to be cut off to achieve the necessary clearance.
The phrase "topping" refers to the practice of cutting off the top 20-40% of the tree's height. Topping a tree is incredibly harmful to a tree, and will leave an ugly tree, whether it lives through being topped or dies in the process. You would be better off either doing a crown reduction (a method of shortening the tree's height without harming it) if the tree only needs to be 5-10% shorter, or removing the tree altogether if it is to large.
