Trees, like people and animals, get sick. How do you reach a “tree doctor” if your trees show symptoms of poor health?
Leaf loss, in one section or across a tree’s entire crown, is the most usual 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 Five! Trained to detect and diagnose diseases and insect pests, these tree specialists prescribe treatments for ailments that affect Wisconsin trees.
Changes in leaf color are another identifier. Yellow leaves can be reflective of a fertilizer deficiency, often with oaks. Yet, yellow is the normal color of leaves on a sunburst locust tree. A Certified Arborist understands the difference, and how to interpret the messages of leaf colors!
Preventing problems is the most sound 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 Five.
What are they hunting for? The aforementioned symptoms, of course. Another sign of potential alarm is crevices or cavities in trees, where moisture and insects collect. The goal is to identify ongoing or potential problems proactively. Blocking a disease or insect infestation is far simpler than curing them once established.
Colorado blue spruces fill many yards. A close look, 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 stop 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 far more resistance to insects and disease. Concolor firs and Norway spruces are substitutes for Colorado spruces.
Other tree species in Lake Five are vulnerable to fungi diseases, too. Oaks suffer oak wilt. Elms contract Dutch elm disease. Proactive inspection can identify these realities 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 selective, 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 lethal bronze birch borer goes after birches. Linden borers mainly target lindens.
The emerald ash borer has been an unwelcome introduction for Lake Five homeowners. The Asian invasive has decimated ash trees across Lake Five and Wisconsin in recent years.
Another invasive, the spotted lanternfly, is moving 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 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 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 Lake Five.
