Trees, like people and animals, get sick. How do you identify a “tree doctor” if your trees show indicators of poor health?
Leaf loss, in one area 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 Vernon! Educated to spot and analyze diseases and insect pests, these tree specialists prescribe solutions for problems that afflict Wisconsin trees.
Alterations in leaf color are another red flag. Yellow leaves can be reflective of a fertilizer shortage, 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!
Avoiding problems is the most efficient 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 Vernon.
What are they watching 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 identify existing or possible problems proactively. Avoiding a disease or insect infestation is much easier than curing them once established.
Colorado blue spruces dot many yards. A close viewing, though, might find 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 thwart the fungus from devastating and eventually killing these beautiful trees.
Another possibility – 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 Vernon 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 block root rot, a condition that affects trees growing in wet soil. Root rot isn’t choosy, either – its decay affects trees from a variety 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 attacks birches. Linden borers mostly target lindens.
The emerald ash borer has been a rude introduction for Vernon homeowners. The Asian invasive has decimated ash trees across Vernon 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.
