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

Trees, like people and animals, get sick. How do you identify 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 typical indicator 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 Greendale! Trained to spot and diagnose diseases and insect pests, these tree specialists prescribe treatments for problems that afflict Wisconsin trees.

Alterations in leaf color are another red flag. Yellow leaves can be reflective of a fertilizer deficiency, often with oaks. Yet, yellow is the normal 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 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 Greendale.

What are they looking for? The aforementioned symptoms, of course. Another sign of concern is crevices or cavities in trees, where moisture and insects collect. The goal is to spot existing or possible problems early. Preventing a disease or insect infestation is far simpler than curing them once established.

Colorado blue spruces occupy many yards. A close inspection, 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 thwart the fungus from decimating and eventually killing these stunning trees.

Another possibility – 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 Greendale are susceptible 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 avoid root rot, a condition that affects trees growing in wet soil. Root rot isn’t picky, 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 introduction for Greendale homeowners. The Asian invasive has decimated ash trees across Greendale 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.

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 Greendale.
