If Your Trees Look Unhealthy, Don’t Wait to Call a “Tree Doctor” in Lake Forest!

Trees, like people and animals, get ill. How do you reach 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 common sign 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 bet for prompt, responsive tree treatment service in Lake Forest! Trained to identify and analyze 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 deficit, often with oaks. However, yellow is the natural 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 Lake Forest.

What are they watching for? The aforementioned symptoms, of course. Another sign of concern is crevices or cavities in trees, where moisture and insects collect. The goal is to identify existing or potential problems early. Preventing a disease or insect infestation is far easier than curing them once established.

Colorado blue spruces fill 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 stop the fungus from devastating and ultimately killing these beautiful trees.

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

Other tree species in Lake Forest are susceptible to fungi diseases, too. Oaks suffer oak wilt. Elms contract Dutch elm disease. Pre-emptive inspection can identify these circumstances 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 variety of species.

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

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