If Your Trees Look Ill, Don’t Wait to Look Up a “Tree Doctor” in Rochester!

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 indicator 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 Rochester! Trained to detect and analyze diseases and insect pests, these tree specialists prescribe solutions for problems that afflict Wisconsin trees.

Alterations in leaf color are another symptom. Yellow leaves can be reflective of a fertilizer shortage, 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 read the messages of leaf colors!

Averting 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 Rochester.

What are they searching 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 spot ongoing 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 look, though, might discover proof 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 stop the fungus from devastating and ultimately killing these stunning trees.

Another possibility – again, long before reaching this point – is planting trees with similar appearance, yet far more resistance to insects and disease. Concolor firs and Norway spruces are substitutes for Colorado spruces.

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

Application of fungicides can prevent root rot, a condition that affects trees growing in wet soil. Root rot isn’t choosy, either – its decay affects trees from a wide range 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 a rude introduction for Rochester homeowners. The Asian invasive has decimated ash trees across Rochester 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.

Preventing 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 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 Rochester.
