Common Pests of Trees

Many landowners and homeowners are recognizing the importance and value of trees in their yards. Trees are a defining characteristic of rural farm yards and homes on the prairies, and many have been on the property for generations. They help to beautify and provide shelter to a yard. They also provide habitat for birds and other animals.

A tall, mature tree can take decades to become well established, and if not properly cared for, can become quite expensive to maintain and even more so to replace. However, if care and attention are given to trees, they can be very beneficial to the landowner and the yard, and will continue to live for many more decades. For example, poplar trees can live 50 years and a spruce tree can live for 200 years or more!
