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

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 area or across a tree’s entire crown, is the most typical 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 top choice for prompt, responsive tree treatment service in Jefferson County! Educated to detect and analyze diseases and insect pests, these tree specialists prescribe remedies for problems that affect Wisconsin trees.


Changes in leaf color are another symptom. Yellow leaves can be reflective of a fertilizer deficit, often with oaks. However, yellow is the normal color of leaves on a sunburst locust tree. A Certified Arborist recognizes the difference, and how to interpret the messages of leaf colors!


Avoiding 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 Jefferson County.


What are they hunting for? The aforementioned symptoms, of course. Another area of potential alarm is crevices or cavities in trees, where moisture and insects collect. The goal is to identify ongoing or possible problems early. Preventing a disease or insect infestation is far easier than curing them once established.


Colorado blue spruces fill many yards. A close look, though, might find 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 stunning trees.


Another option – 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 alternatives to Colorado spruces.


Other tree species in Jefferson 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 avoid root rot, an ailment that afflicts trees growing in wet soil. Root rot isn’t selective, either – its decay affects trees from a multitude 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 attacks birches. Linden borers mainly target lindens. 


The emerald ash borer has been a rude initiation for Jefferson County homeowners. The Asian invasive has decimated ash trees across Jefferson 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 damage, 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 visiting a doctor for years on end, don’t gamble with the well-being of your trees. Contact Dorshak Tree Specialists for a complimentary checkup. Yes, their “tree doctors” still make house calls to Jefferson County.
