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

Trees, like people and animals, get sick. How do you locate 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 common sign 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 Jefferson County! Educated to spot and analyze diseases and insect pests, these tree specialists prescribe solutions for problems that affect Wisconsin trees.

Changes in leaf color are another symptom. Yellow leaves can be symptomatic of a fertilizer deficiency, often with oaks. However, yellow is the natural color of leaves on a sunburst locust tree. A Certified Arborist understands the difference, and how to read the messages of leaf colors!

Avoiding 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 Jefferson County.

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

Colorado blue spruces dot many yards. A close viewing, though, might discover signs 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 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 Jefferson County are susceptible 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, an ailment that afflicts trees growing in wet soil. Root rot isn’t choosy, either – its decay affects trees from a multitude 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 attacks birches. Linden borers mainly target lindens. 

The emerald ash borer has been a rude introduction 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 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 absorb.

Just as you wouldn’t miss seeing 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.
