I.V. Tree Care was started in 1999 by Certified Arborist Olen Sharron after retiring from the USDA. Olen was dedicated to saving Hemlock trees from the deadly Hemlock Woolly Adelgid (HWA), an imported insect that has killed millions of trees. Unfortunately, Olen passed away in August 2007 after a valiant battle with cancer.
In February 2008, Virginia Tech graduate (MS Horticulture) and ISA Certified Arborist Jim May took over the business and has continued to save thousands of Hemlocks in Southwest Virginia.
Jim has even expanded the business to cover many more insect and disease problems, including the Emerald Ash Borer (EAB), Scale insects, Lacebugs, Aphids, Fall webworm and other biting and sucking insects. Diseases controlled by I.V. Tree Care include Bacterial Leaf Scorch (BLS), Anthracnose, Dutch Elm Disease (DED) and others.
Jim constantly continues to learn about new insect and disease problems through seminars, webinars and other Certified Arborists. Maintaining his CEU's to keep up with his certifications as an ISA Certified Arborist, Certified Tree Risk Assessor, Virginia Certified Horticulturist and Virginia Certified Pesticide Applicator is another full-time job.
Jim May came to the New River Valley in 1980 and except for a few years in Richmond, has lived in Blacksburg, Radford and now Christiansburg. He was educated at Virginia Tech where he earned a Master's Degree in Horticulture. Experienced in the nursery industry and a former Extension Agent, he is also a(n):
His specialty is plant health care (PHC), including:
Jim also has extensive knowledge in:
Tree injections have been used for over 50 years as a method of:
The first method, developed by J.J. Mauget in the early 1960's, involved:
While that method is still employed today, newer technologies have added to the arborists' tool kit. Now there are:
Fungicides and some micro-nutrients, such as Iron, need to be injected directly into the xylem of the tree. This area transports water and nutrients upward to the leaves.
Injections of fertilizers and systemic insecticides into the soil and root zone around trees is also very effective and widely used. The chemical is then taken up by the tree's roots and transported throughout the branches and leaves. Fall fertilization is especially effective if done by soil injection.
Another way to introduce systemic insecticides is called bark banding, where a systemic chemical, usually mixed with a surfactant, is sprayed onto the bark where it is absorbed and transported throughout the tree.
