If Your Trees Look Sick, Don’t Wait to Contact a “Tree Doctor” in North Bay!

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

Leaf loss, in one area or across a tree’s entire crown, is the most typical indicator 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 best choice for prompt, responsive tree treatment service in North Bay! Educated to recognize and analyze diseases and insect pests, these tree specialists prescribe treatments for ailments that affect Wisconsin trees.

Changes in leaf color are another symptom. Yellow leaves can be reflective of a fertilizer deficiency, often with oaks. Yet, yellow is the normal color of leaves on a sunburst locust tree. A Certified Arborist understands the difference, and how to translate 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 North Bay.

What are they looking for? The aforementioned symptoms, of course. Another area of concern is crevices or cavities in trees, where moisture and insects gather. The goal is to spot ongoing or potential problems proactively. Avoiding a disease or insect infestation is far simpler than curing them once established.

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

Another possibility – 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 substitutes for Colorado spruces.

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

Application of fungicides can prevent root rot, a condition that afflicts trees growing in wet soil. Root rot isn’t picky, either – its decay affects trees from a multitude of species.

Insect pests pose serious threats 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 North Bay homeowners. The Asian invasive has decimated ash trees across North Bay and Wisconsin in recent years.

Another invasive, the spotted lanternfly, is heading 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 skip visiting a doctor for years on end, don’t gamble with the well-being of your trees. Contact Dorshak Tree Specialists for a complimentary checkup. Yes, their “tree doctors” still make house calls to North Bay.
