If Your Trees Look Sick, Don’t Wait to Summon a “Tree Doctor” in Saint Lawrence!

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

Leaf loss, in one section or across a tree’s entire crown, is the most usual evidence 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 best bet for prompt, responsive tree treatment service in Saint Lawrence! Educated to spot and analyze diseases and insect pests, these tree specialists prescribe treatments for problems that affect Wisconsin trees.

Changes in leaf color are another symptom. Yellow leaves can be reflective of a fertilizer shortage, often with oaks. However, 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 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 Saint Lawrence.

What are they watching 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 early. Blocking a disease or insect infestation is much simpler than curing them once established.

Colorado blue spruces dot many yards. A close inspection, though, might discover proof 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 stop the fungus from devastating and eventually killing these beautiful trees.

Another option – again, long before reaching this point – is planting trees with similar appearance, yet far more resistance to insects and disease. Concolor firs and Norway spruces are substitutes for Colorado spruces.

Other tree species in Saint Lawrence are vulnerable to fungi diseases, too. Oaks suffer oak wilt. Elms contract Dutch elm disease. Pre-emptive inspection can identify these realities in time to save the trees.

Application of fungicides can block root rot, a condition that affects 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 deadly bronze birch borer goes after birches. Linden borers mostly target lindens. 

The emerald ash borer has been an unwelcome introduction for Saint Lawrence homeowners. The Asian invasive has decimated ash trees across Saint Lawrence 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.

Avoiding insect harm, 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 skip 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 Saint Lawrence.
