Trees, like people and animals, get sick. How do you find a “tree doctor” if your trees show evidence of poor health?
Leaf loss, in one area or across a tree’s entire crown, is the most typical sign 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 bet for prompt, responsive tree treatment service in Thompson! Educated to identify and analyze diseases and insect pests, these tree specialists prescribe solutions for problems that afflict Wisconsin trees.
Changes in leaf color are another symptom. Yellow leaves can be reflective of a fertilizer deficiency, often with oaks. However, 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 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 Thompson.
What are they hunting for? The aforementioned symptoms, of course. Another area of potential alarm is crevices or cavities in trees, where moisture and insects collect. The goal is to identify ongoing or possible problems early. Avoiding a disease or insect infestation is much easier 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 collected needles beneath a tree, are a symptom. Treatment can halt the fungus from decimating and ultimately killing these stunning 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 alternatives to Colorado spruces.
Other tree species in Thompson are vulnerable to fungi diseases, too. Oaks suffer oak wilt. Elms contract Dutch elm disease. Pre-emptive inspection can identify these conditions in time to save the trees.
Application of fungicides can block root rot, an ailment that afflicts trees growing in wet soil. Root rot isn’t selective, 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 deadly bronze birch borer attacks birches. Linden borers mostly target lindens.
The emerald ash borer has been a rude introduction for Thompson homeowners. The Asian invasive has decimated ash trees across Thompson 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.
Blocking insect harm, 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 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 Thompson.
