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

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 common evidence 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 top choice for prompt, responsive tree treatment service in Koshkonong! Trained to detect and analyze diseases and insect pests, these tree specialists prescribe remedies for problems that afflict Wisconsin trees.

Changes in leaf color are another identifier. Yellow leaves can be symptomatic of a fertilizer deficiency, often with oaks. However, yellow is the normal color of leaves on a sunburst locust tree. A Certified Arborist recognizes 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 Koshkonong.

What are they hunting for? The aforementioned symptoms, of course. Another sign of concern is crevices or cavities in trees, where moisture and insects collect. The goal is to spot ongoing or possible problems early. Preventing a disease or insect infestation is much easier than curing them once established.

Colorado blue spruces dot many yards. A close viewing, though, might find 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 decimating and eventually killing these lovely trees.

Another possibility – 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 substitutes for Colorado spruces.

Other tree species in Koshkonong are susceptible to fungi diseases, too. Oaks suffer oak wilt. Elms contract Dutch elm disease. Proactive inspection can identify these conditions 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 picky, either – its decay affects trees from a wide range of species.

Insect pests pose serious dangers 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 an unwelcome introduction for Koshkonong homeowners. The Asian invasive has decimated ash trees across Koshkonong 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 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 skip seeing a doctor for years on end, don’t risk the well-being of your trees. Contact Dorshak Tree Specialists for a complimentary checkup. Yes, their “tree doctors” still make house calls to Koshkonong.
