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

Trees, like people and animals, get sick. How do you reach 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 common indicator 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 best bet for prompt, responsive tree treatment service in Saint Lawrence! Educated to spot and diagnose diseases and insect pests, these tree specialists prescribe solutions for problems that afflict Wisconsin trees.

Alterations in leaf color are another identifier. 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 recognizes the difference, and how to interpret the messages of leaf colors!

Avoiding problems is the most sound 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 looking for? The aforementioned symptoms, of course. Another area of concern is crevices or cavities in trees, where moisture and insects gather. The goal is to spot existing or potential problems early. Preventing a disease or insect infestation is much simpler than curing them once established.

Colorado blue spruces fill many yards. A close viewing, though, might find 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 lovely trees.

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

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

Insect pests pose serious threats 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 a rude initiation 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 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.

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 miss seeing 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 Saint Lawrence.
