If Your Trees Look Ill, Don’t Wait to Look Up a “Tree Doctor” in Oak Hill!

Trees, like people and animals, get ill. How do you identify a “tree doctor” if your trees show indicators of poor health?

Leaf loss, in one section or across a tree’s entire crown, is the most typical evidence of a problem. Mushroom growth, typically from a trunk or base, is another. A spate of dead limbs can be a symptom.

An ISA-Certified Arborist from Dorshak Tree Specialists is your top choice for prompt, responsive tree treatment service in Oak Hill! Trained to recognize and diagnose diseases and insect pests, these tree specialists prescribe treatments for ailments that afflict Wisconsin trees.

Changes in leaf color are another symptom. Yellow leaves can be evidence of a fertilizer deficiency, often with oaks. Yet, yellow is the natural color of leaves on a sunburst locust tree. A Certified Arborist recognizes the difference, and how to read the messages of leaf colors!

Preventing problems is the most effective approach to tree health. It’s advisable to have your trees inspected every three to five years by a Certified Arborist. Dorshak Tree Service, with seven Certified Arborists on staff, offers this service for free for tree owners in and around Oak Hill.

What are they looking for? The aforementioned symptoms, of course. Another sign of note is crevices or cavities in trees, where moisture and insects gather. The goal is to identify existing or possible problems proactively. Blocking a disease or insect infestation is far easier than curing them once established.

Colorado blue spruces dot many yards. A close look, though, might discover proof of Rhizosphaera needle cast, a fungus that attacks this non-native species. Brown needles, or collected needles beneath a tree, are a symptom. Treatment can halt the fungus from devastating and ultimately killing these lovely trees.

Another option – again, long before reaching this point – is planting trees with similar appearance, yet much more resistance to insects and disease. Concolor firs and Norway spruces are alternatives to Colorado spruces.

Other tree species in Oak Hill are susceptible to fungi diseases, too. Oaks suffer oak wilt. Elms contract Dutch elm disease. Proactive inspection can identify these conditions in time to save the trees.

Application of fungicides can prevent root rot, an ailment that affects trees growing in wet soil. Root rot isn’t selective, either – its decay affects trees from a variety of species.

Insect pests pose serious dangers to residential trees. Insects are usually host specific, meaning they target one species. The lethal bronze birch borer goes after birches. Linden borers mostly target lindens. 

The emerald ash borer has been an unwelcome introduction for Oak Hill homeowners. The Asian invasive has decimated ash trees across Oak Hill and Wisconsin in recent years.

Another invasive, the spotted lanternfly, is inching west after its discovery in Pennsylvania in 2014. The China native feeds on more than 70 tree species, including maples, oaks, lindens, hickory and black walnut.

Avoiding insect harm, once again, is about proactivity. Repellents are applied in two ways: injecting directly into trees, or drenching soil beneath for roots to absorb.

Just as you wouldn’t miss visiting a doctor for years on end, don’t risk the well-being of your trees. Contact Dorshak Tree Specialists for a complimentary checkup. Yes, their “tree doctors” still make house calls to Oak Hill.
