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

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 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 top choice for prompt, responsive tree treatment service in Sullivan! Educated to recognize and diagnose diseases and insect pests, these tree specialists prescribe remedies for ailments that affect Wisconsin trees.

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

Avoiding 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 Sullivan.

What are they watching for? The aforementioned symptoms, of course. Another sign of potential alarm 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 fill many yards. A close viewing, though, might discover signs 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 block 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 far more resistance to insects and disease. Concolor firs and Norway spruces are substitutes for Colorado spruces.

Other tree species in Sullivan 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 prevent root rot, a condition that afflicts trees growing in wet soil. Root rot isn’t picky, either – its decay affects trees from a multitude 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 attacks birches. Linden borers mostly target lindens. 

The emerald ash borer has been a rude initiation for Sullivan homeowners. The Asian invasive has decimated ash trees across Sullivan and Wisconsin in recent years.

Another invasive, the spotted lanternfly, is moving 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 skip 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 Sullivan.
