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

Trees, like people and animals, get ill. 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 common symptom 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 Chicago! Trained to recognize and diagnose diseases and insect pests, these tree specialists prescribe remedies for problems that afflict Wisconsin trees.

Alterations in leaf color are another red flag. Yellow leaves can be symptomatic of a fertilizer deficit, often with oaks. However, yellow is the normal color of leaves on a sunburst locust tree. A Certified Arborist knows the difference, and how to interpret 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 Chicago.

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

Colorado blue spruces fill many yards. A close viewing, though, might discover evidence of Rhizosphaera needle cast, a fungus that attacks this non-native species. Brown needles, or collected needles beneath a tree, are a giveaway. Treatment can block the fungus from devastating and eventually killing these lovely trees.

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

Other tree species in Chicago 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, a condition that affects trees growing in wet soil. Root rot isn’t selective, either – its decay affects trees from a wide range 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 a rude initiation for Chicago homeowners. The Asian invasive has decimated ash trees across Chicago 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.

Preventing 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 skip seeing 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 Chicago.
