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

Trees, like people and animals, get ill. How do you find 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 evidence 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 best choice for prompt, responsive tree treatment service in Theresa! Educated to spot and diagnose diseases and insect pests, these tree specialists prescribe remedies for ailments that affect 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 natural color of leaves on a sunburst locust tree. A Certified Arborist knows the difference, and how to translate the messages of leaf colors!

Avoiding problems is the most effective 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 Theresa.

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 potential problems proactively. Blocking a disease or insect infestation is much simpler than curing them once established.

Colorado blue spruces fill many yards. A close inspection, though, might discover signs of Rhizosphaera needle cast, a fungus that attacks this non-native species. Brown needles, or collected needles beneath a tree, are a giveaway. Treatment can stop the fungus from devastating and eventually killing these stunning 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 Theresa are vulnerable 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 choosy, 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 a rude introduction for Theresa homeowners. The Asian invasive has decimated ash trees across Theresa 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 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 Theresa.
