If Your Trees Look Unhealthy, Don’t Wait to Summon 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, 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 bet for prompt, responsive tree treatment service in Jefferson County! Educated to recognize and analyze diseases and insect pests, these tree specialists prescribe treatments for ailments that afflict Wisconsin trees.

Alterations 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 understands the difference, and how to read the messages of leaf colors!

Averting problems is the most effective 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 area of note is crevices or cavities in trees, where moisture and insects gather. The goal is to identify existing or potential problems early. Blocking a disease or insect infestation is far simpler than curing them once established.

Colorado blue spruces dot many yards. A close look, though, might find proof 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 beautiful 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 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. Proactive inspection can identify these realities in time to save the trees.

Application of fungicides can avoid root rot, a condition that affects trees growing in wet soil. Root rot isn’t choosy, 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 deadly bronze birch borer goes after 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 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.

Avoiding 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 absorb.

Just as you wouldn’t miss seeing 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.
