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 identify a “tree doctor” if your trees show indicators of poor health?

Leaf loss, in one section 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 bet for prompt, responsive tree treatment service in Jefferson County! Educated to identify and diagnose diseases and insect pests, these tree specialists prescribe treatments for problems that affect Wisconsin trees.

Changes in leaf color are another symptom. Yellow leaves can be evidence of a fertilizer deficit, often with oaks. Yet, yellow is the normal color of leaves on a sunburst locust tree. A Certified Arborist understands the difference, and how to translate 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 area of potential alarm is crevices or cavities in trees, where moisture and insects gather. The goal is to identify ongoing or possible problems proactively. Blocking a disease or insect infestation is far simpler 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 giveaway. Treatment can block the fungus from decimating and eventually killing these beautiful trees.

Another possibility – 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. Pre-emptive inspection can identify these realities 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 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 goes after birches. Linden borers mainly target lindens. 

The emerald ash borer has been an unwelcome 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 miss visiting a doctor for years on end, don’t risk the health of your trees. Contact Dorshak Tree Specialists for a complimentary checkup. Yes, their “tree doctors” still make house calls to Jefferson County.
