Frequently Asked Questions

Why Hire an Arborist?

An arborist is a specialist in the care of individual trees. Arborists are knowledgeable about the needs of trees and are trained and equipped to provide proper care. Proper tree care is an investment that can lead to substantial returns. Well-cared-for trees are attractive and can add considerable value to your property. Poorly maintained trees can be a significant liability. Pruning or removing trees, especially large trees, can be dangerous work. Tree work should be done only by those trained and equipped to work safely in trees. An arborist can determine the type of pruning that is necessary to improve the health, appearance, and safety of your trees. A professional arborist can provide the services of a trainedcrew, with all of the required safety equipment and liability insurance.


What does pruning do?

  • eliminates branches that rub each other
  • removes limbs that interfere with wires, building facades, gutters, roofs, chimneys, or windows, or that obstruct streets or sidewalks
  • removes dead or weak limbs that pose a hazard or may lead to decay
  • removes diseased or insect-infested limbs
  • creates better structure to lessen wind resistance and reduce the potential for storm damage
  • trains young trees
  • removes limbs damaged by adverse weather conditions
  • removing branches, or thinning, to increase light penetration
  • improves the shape of the tree

When should a tree be removed?

  • when it is dead or dying
  • when it is considered irreparably hazardous
  • when it is causing an obstruction that is impossible to correct through pruning
  • when it is crowding and causing harm to other trees
  • when it is to be replaced by a more suitable specimen
  • when it is located in an area where new construction requires removal

What is Topping?

Topping is the indiscriminate cutting of tree branches to stubs to reduce the size of the tree. Other names for topping include “heading,” “tipping,” “hat-racking,” and “rounding over.” Topping is perhaps the most harmful tree pruning practice known. Yet, topping remains a common practice. Home owners often feel that their trees have become too large for their property. People fear that tall trees may pose a hazard. Topping, however, is not a viable method of height reduction and certainly does not reduce the hazard. In fact, topping will make a tree more hazardous in the long run. Topping is not an acceptable pruning technique and there are better alternatives.

  • Topping Stresses Trees
    Topping often removes 50 to 100 percent of the leaf-bearing crown of a tree. Because leaves are the food factories of a tree, removing them can temporarily starve a tree. The severity of the pruning triggers a sort of survival mechanism. The tree activates latent buds, forcing the rapid growth of multiple shoots below each cut. The tree needs to put out a new crop of leaves as soon as possible. If a tree does not have the stored energy reserves to do so, it will be seriously weakened and may die.
  • Topping Causes Decay
    The preferred location to make a pruning cut is just beyond the branch collar at the branch’s point of attachment. The tree is biologically equipped to close such a wound, provided the tree is healthy enough and the wound is not too large. Cuts made along a limb between lateral branches create stubs with wounds that the tree may not be able to close. The exposed wood tissues begin to decay. Normally, a tree will “wall off,” or compartmentalize, the decaying tissues, but few trees can defend the multiple severe wounds caused by topping. The decay organisms are given a free path to move down through the branches.
  • Topping Can Lead to Sunburn
    Branches within a tree’s crown produce thousands of leaves to absorb sunlight. When the leaves are removed, the remaining branches and trunk are suddenly exposed to high levels of light and heat. The result may be sunburn of the tissues beneath the bark, which can lead to cankers, bark splitting, and death of some branches.
  • Topping Creates Hazards
    The survival mechanism that causes a tree to produce multiple shoots below each topping cut comes at great expense to the tree. These shoots develop from buds near the surface of the old branches. Unlike normal branches that develop in a socket of overlapping wood tissues, these new shoots are anchored only in the outermost layers of the parent branches. The new shoots grow quickly, as much as 20 feet in one year, in some species. Unfortunately, the shoots are prone to breaking, especially during windy conditions. The irony is that while the goal was to reduce the tree’s height to make it safer, it has been made more hazardous than before.
  • Topping Makes Trees Ugly
    Topping removes the ends of the branches, often leaving ugly stubs. Topping destroys the natural form of a tree. Without leaves (up to 6 months of the year), a topped tree appears disfigured and mutilated. With leaves, it is a dense ball of foliage, lacking its simple grace. A tree that has been topped can never fully regain its natural form.
