Properly trimmed trees have a better chance to survive through all types of storms. Many trees that are damaged through storms could have been prevented if they were trimmed properly.
Besides being aesthetically pleasing to the eye, properly trimmed trees allow the wind to travel through easier, therefore reducing the possibility of branches breaking.
The cost of having properly trimmed trees is far less than its removal after being damaged. We also never use spikes when pruning trees. Spikes can encourage insect infestation and disease.
