When a tree gets seriously damaged, some homeowners find it challenging to determine if it is best to have the tree cleared away. Dying trees that do not pose danger on people or properties may be allowed to stand in place up until it dies. Aged deceased trees may also be very useful to certain species of wood peckers as a source of food and a good spot to nest. While some property owners tend to keep their tree for as long as possible by pruning out damaged or diseased areas of the tree and watering the tree deeply as required. Nevertheless, consistent clearing of weakened tree parts is costly and there may also be concerns about the tree falling unexpectedly on people and properties. So, to prevent the hazards and added expenses on sustaining an old or damaged tree, you have to make a decision on whether to remove the tree. Here are a number of guidelines to help you to come up with the best choice.
1. Know whether the tree is a desirable or undesirable specie. The characteristics of undesirable tree species include shallow roots that may damage pavements and lawns, prone to insect or disease infestation, weak wood that is prone to breakage, drops too many debris, and intrusive by means of extensive reseeding. Examples of undesirable trees are Siberian elm, black locust, box elder, poplars, mulberry, silver maple, mimosa, willows, empress tree, tree of heaven and Bradford pear.
2. Look into the general health of the tree. If nearly 50 % of your tree is hurt, it is best to have it taken down. Although an injured or damaged tree may survive for a number of years.
3. Is the trunk damaged? Seams, vertical cracks, large wounds and dead branch stubs are signs of internal decay. If the main trunk is severely damaged, the tree should be removed. However, if the damage is not more than 25% of the total circumference of the trunk, then there’s no need to worry. The wound is likely to heal overtime.
4. Determine if the tree is hollow. It is best to remove a tree if 1/3 of its interior is rotten or hollow. Hollow or rotten interior will compromise the strength of the trunk, making the tree dangerous.
5. Is the tree sagging? A sudden inclination of a tree is a sign of weak roots or breakage. Thus, leaning trees should be removed immediately particularly those that are stooped greater than 15 % of a vertical position.
