Meet Joe Aiken

Joe’s 30-plus years in the tree care industry have provided a diverse and valuable experience which has permitted him to guide others in plant health care decisions. He has worked in all phases of tree care, and as a licensed applicator and an ISA certified arborist, he developed a strong interest in Plant Health Care and gained the experience and desire to continue his education.

Joe routinely conducts product seminars and presentations on various treatment methods which are attended by arborists, city foresters, plant health care technicians, master gardeners, university extension agents, grounds departments, and research personnel. He also supports Arborjet’s research department and co-operating universities, assisting with tree injections on research sites, and other aspects of research required to aide in development of equipment and formulations needed to control today’s invasive pests.

Joe is a proud founding member of the Arboriculture Society of Michigan Foundation and Curator of the Arboriculture Historical Society. In 2001 Joe joined the team at Arborjet, where he shares his strong belief in tree preservation with clients, and educates others on the benefit of more environmentally friendly solutions for our urban forest problems.

Oak Wilt

The fungus is spread through root grafts between neighboring trees and by insects. Red Oaks are particularly susceptible to oak wilt. The infection causes leaf discoloration, defoliation and death in a very short period of time (from two months to one year).

Hemlock Woolly Adelgid

HWA is an invasive species from Asia which has infested the US East Coast hemlock forest from New Hampshire to Georgia, inhibiting twig growth throughout.  It has also recently been found in Michigan and it is believed to be expanding its range due to changes in climate.

Iron or manganese chlorosis (interveinal chlorosis) describes a condition in which a tree’s foliage loses its healthy green color and fades to a pale green or yellow hue. This condition, if allowed to progress, will cause slow growth, leaf loss, and eventually tree death.
