If Your Trees Look Unhealthy, Don’t Wait to Look For a “Tree Doctor” in Guthrie!

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

Leaf loss, in one section or across a tree’s entire crown, is the most common sign 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 top choice for prompt, responsive tree treatment service in Guthrie! Educated to identify and analyze diseases and insect pests, these tree specialists prescribe treatments for ailments that afflict Wisconsin trees.

Alterations in leaf color are another identifier. Yellow leaves can be evidence of a fertilizer deficit, often with oaks. Yet, yellow is the natural color of leaves on a sunburst locust tree. A Certified Arborist knows the difference, and how to read the messages of leaf colors!

Preventing problems is the most efficient 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 Guthrie.

What are they watching for? The aforementioned symptoms, of course. Another area of note is crevices or cavities in trees, where moisture and insects collect. The goal is to identify ongoing or possible problems proactively. Preventing a disease or insect infestation is much simpler than curing them once established.

Colorado blue spruces fill many yards. A close look, though, might find evidence 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 block the fungus from decimating and ultimately killing these beautiful 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 Guthrie are vulnerable to fungi diseases, too. Oaks suffer oak wilt. Elms contract Dutch elm disease. Pre-emptive inspection can identify these circumstances in time to save the trees.

Application of fungicides can block root rot, an ailment that affects trees growing in wet soil. Root rot isn’t selective, either – its decay affects trees from a multitude 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 an unwelcome introduction for Guthrie homeowners. The Asian invasive has decimated ash trees across Guthrie 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.

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 take in.

Just as you wouldn’t miss visiting a doctor for years on end, don’t gamble with the health of your trees. Contact Dorshak Tree Specialists for a complimentary checkup. Yes, their “tree doctors” still make house calls to Guthrie.
