Deadwood within trees, especially mature trees, is a fairly common occurrence, and is typically caused by two different processes. First, it’s possible that the heartwood of the branch is hollowed out because of fungal colonization. Secondly, storms, disease, lack of enough sap, or even lack of water can cause decay of the bark. When this happens, the branch may end up dying.

Deadwood within trees is actually a natural process for some fast growing tree species, such as birch, silver maple, and locusts. These and other trees have small interior branches that may not receive enough sunlight. Smaller branches tend to be less useful to the growth of the tree and therefore, the tree sends more sap to the larger branches that support the tree. When the sap supply is cut off, as it eventually is, the smaller branches die.

While it may not seem important, there are many reasons why deadwood should be removed:

-When deadwood breaks off in a thunderstorm the heartwood of the tree is exposed. The area of the tree where a branch has broken off exposes the heartwood of the tree, which can allow insects to penetrate and create a home. Water can also accumulate which can result in fungus and other forms of decay – this can eventually lead to trunk rot.

-As mentioned above, deadwood can break off during a storm and even light winds. When this happens, it can cause property damage and injury. Deadwood removal can help eliminate liability concerns – which is of particular concern when dealing with branches greater than 2 inches in diameter.

-A large amount of deadwood is not aesthetically pleasing. Removal will help to improve the overall balance of the tree. A lot of deadwood will prevent wind from blowing through the tree, which can result in damage, or even the total destruction, of the tree.

-Deadwood also reduces the tree’s capability to grow into its proper shape. If the deadwood blocks sunlight to much of the tree, then the tree will not grow into a beautiful and full shape.
