If Your Trees Look Sick, Don’t Wait to Look For a “Tree Doctor” in Eagle!

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

Leaf loss, in one section or across a tree’s entire crown, is the most typical indicator of a problem. Mushroom growth, regularly 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 best bet for prompt, responsive tree treatment service in Eagle! Trained to recognize and diagnose diseases and insect pests, these tree specialists prescribe treatments for problems that afflict Wisconsin trees.

Alterations in leaf color are another red flag. Yellow leaves can be reflective of a fertilizer deficiency, often with oaks. However, yellow is the natural color of leaves on a sunburst locust tree. A Certified Arborist understands the difference, and how to interpret the messages of leaf colors!

Avoiding 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 Eagle.

What are they hunting for? The aforementioned symptoms, of course. Another area of note is crevices or cavities in trees, where moisture and insects collect. The goal is to identify ongoing or potential problems early. Blocking a disease or insect infestation is much simpler than curing them once established.

Colorado blue spruces fill many yards. A close inspection, 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 block the fungus from decimating and eventually killing these lovely trees.

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

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

Application of fungicides can block root rot, an ailment that afflicts trees growing in wet soil. Root rot isn’t choosy, either – its decay affects trees from a wide range 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 attacks birches. Linden borers mainly target lindens. 

The emerald ash borer has been an unwelcome introduction for Eagle homeowners. The Asian invasive has decimated ash trees across Eagle 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.

Blocking insect harm, once again, is often a matter of 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 gamble with the health of your trees. Contact Dorshak Tree Specialists for a complimentary checkup. Yes, their “tree doctors” still make house calls to Eagle.
