Trees, like people and animals, get sick. How do you locate a “tree doctor” if your trees show signs 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 Washington County! Trained to detect and analyze diseases and insect pests, these tree specialists prescribe solutions for problems that afflict Wisconsin trees.
Changes in leaf color are another identifier. Yellow leaves can be reflective of a fertilizer deficit, often with oaks. Yet, yellow is the normal color of leaves on a sunburst locust tree. A Certified Arborist recognizes the difference, and how to translate the messages of leaf colors!
Preventing 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 Washington County.
What are they looking 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 possible problems early. Avoiding a disease or insect infestation is far easier than curing them once established.
Colorado blue spruces occupy many yards. A close viewing, though, might find 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 thwart the fungus from devastating and ultimately killing these lovely trees.
Another possibility – 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 Washington County are vulnerable to fungi diseases, too. Oaks suffer oak wilt. Elms contract Dutch elm disease. Proactive inspection can identify these circumstances in time to save the trees.
Application of fungicides can prevent root rot, a condition that afflicts trees growing in wet soil. Root rot isn’t picky, either – its decay affects trees from a wide range 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 initiation for Washington County homeowners. The Asian invasive has decimated ash trees across Washington 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.
Avoiding insect harm, once again, is about proactivity. Repellents are applied in two ways: injecting directly into trees, or drenching soil beneath for roots to take in.
Just as you wouldn’t miss visiting 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 Washington County.
