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

Trees, like people and animals, get ill. How do you locate a “tree doctor” if your trees show symptoms of poor health?

Leaf loss, in one section or across a tree’s entire crown, is the most usual symptom of a problem. Mushroom growth, typically 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 Rochester! Trained 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 red flag. Yellow leaves can be symptomatic 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 interpret 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 looking for? The aforementioned symptoms, of course. Another sign of note 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 simpler than curing them once established.

Colorado blue spruces fill many yards. A close viewing, though, might find 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 thwart the fungus from devastating and eventually killing these lovely 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 Rochester are vulnerable 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 avoid root rot, a condition that afflicts trees growing in wet soil. Root rot isn’t selective, 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 lethal bronze birch borer goes after birches. Linden borers mostly 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.

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 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 Rochester.
