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

Trees, like people and animals, get ill. How do you reach 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 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 top choice for prompt, responsive tree treatment service in Jefferson County! Educated to recognize and diagnose diseases and insect pests, these tree specialists prescribe treatments for problems that afflict Wisconsin trees.

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

Preventing problems is the most efficient 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 searching for? The aforementioned symptoms, of course. Another sign of concern is crevices or cavities in trees, where moisture and insects gather. The goal is to identify existing or potential problems proactively. Blocking a disease or insect infestation is far easier than curing them once established.

Colorado blue spruces occupy many yards. A close inspection, though, might discover signs of Rhizosphaera needle cast, a fungus that attacks this non-native species. Brown needles, or collected needles beneath a tree, are a symptom. Treatment can thwart the fungus from devastating and eventually killing these beautiful trees.

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

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

Application of fungicides can block 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 threats to residential trees. Insects are usually host specific, meaning they target one species. The deadly bronze birch borer attacks birches. Linden borers mostly target lindens. 

The emerald ash borer has been an unwelcome 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 inching 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 damage, 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 skip 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.
