If Your Trees Look Unhealthy, Don’t Wait to Look For a “Tree Doctor” in Washington County!

Trees, like people and animals, get ill. How do you find 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, 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 choice for prompt, responsive tree treatment service in Washington County! Trained to spot and analyze diseases and insect pests, these tree specialists prescribe treatments for problems that afflict Wisconsin trees.


Changes in leaf color are another red flag. Yellow leaves can be reflective of a fertilizer deficit, often with oaks. Yet, yellow is the natural color of leaves on a sunburst locust tree. A Certified Arborist knows the difference, and how to read the messages of leaf colors!


Averting 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 Washington County.


What are they hunting for? The aforementioned symptoms, of course. Another sign of note is crevices or cavities in trees, where moisture and insects gather. The goal is to spot ongoing or possible problems proactively. Avoiding a disease or insect infestation is much easier than curing them once established.


Colorado blue spruces fill many yards. A close viewing, 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 eventually killing these stunning trees.


Another option – again, long before reaching this point – is planting trees with similar appearance, yet much more resistance to insects and disease. Concolor firs and Norway spruces are substitutes for Colorado spruces.


Other tree species in Washington County are susceptible to fungi diseases, too. Oaks suffer oak wilt. Elms contract Dutch elm disease. Pre-emptive inspection can identify these realities in time to save the trees.


Application of fungicides can avoid root rot, a condition 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 a rude 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 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.


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 take in.


Just as you wouldn’t skip seeing 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.
