Trees do die and there is little that can be done to reverse the process once it is noticed. By the time most people notice a tree dying, there is little to do but plant new trees nearby. Nature plants new trees all the time and when an old tree dies, there are young ones already filling the gap. In our landscapes, we tend to assume that our statuesque, isolated trees will live forever. Consider locations to start new trees near or even under large trees before they even start to decline and prune low branches to accommodate the new tree as it grows.

Arboretum staff do not do site visits or diagnosis over the phone. Tree care and maintenance inquiries are directed to the Yellow Pages under Tree Service to locate a certified arborist. We recommend a second opinion on serious tree problems and arborists serving your area can also be contacted through the International Society of Arboriculture Ontario [1] which also provides information and other resources.
