Trees, like people and animals, get sick. How do you reach a “tree doctor” if your trees show signs of poor health?
Leaf loss, in one area or across a tree’s entire crown, is the most typical evidence 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 top choice for prompt, responsive tree treatment service in Ozaukee County! Trained to recognize and diagnose diseases and insect pests, these tree specialists prescribe solutions for problems that affect Wisconsin trees.
Changes in leaf color are another red flag. Yellow leaves can be reflective of a fertilizer deficit, 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 read the messages of leaf colors!
Averting 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 Ozaukee County.
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 ongoing or potential problems proactively. Avoiding a disease or insect infestation is much easier than curing them once established.
Colorado blue spruces occupy many yards. A close inspection, though, might discover evidence 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 stop the fungus from devastating and ultimately killing these beautiful trees.
Another option – 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 alternatives to Colorado spruces.
Other tree species in Ozaukee County 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, 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 deadly bronze birch borer goes after birches. Linden borers mostly target lindens.
The emerald ash borer has been an unwelcome introduction for Ozaukee County homeowners. The Asian invasive has decimated ash trees across Ozaukee County 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 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 gamble with the health of your trees. Contact Dorshak Tree Specialists for a complimentary checkup. Yes, their “tree doctors” still make house calls to Ozaukee County.
