If Your Trees Look Ill, Don’t Wait to Summon a “Tree Doctor” in Oconomowoc Lake!

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

Leaf loss, in one section or across a tree’s entire crown, is the most usual symptom of a problem. Mushroom growth, usually 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 Oconomowoc Lake! Trained to recognize and diagnose diseases and insect pests, these tree specialists prescribe remedies for ailments that affect Wisconsin trees.

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

Averting problems is the most practical 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 Oconomowoc Lake.

What are they searching for? The aforementioned symptoms, of course. Another area of potential alarm is crevices or cavities in trees, where moisture and insects gather. The goal is to spot existing or potential problems proactively. Blocking a disease or insect infestation is much easier 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 symptom. Treatment can halt the fungus from decimating and eventually killing these stunning 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 Oconomowoc Lake 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 a rude initiation for Oconomowoc Lake homeowners. The Asian invasive has decimated ash trees across Oconomowoc Lake 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.

Blocking insect damage, 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 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 Oconomowoc Lake.
