Trees, like people and animals, get sick. How do you locate 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 sign 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 bet for prompt, responsive tree treatment service in Jefferson County! Educated to detect and analyze 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 evidence of a fertilizer shortage, often with oaks. Yet, yellow is the normal color of leaves on a sunburst locust tree. A Certified Arborist recognizes the difference, and how to interpret 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 Jefferson County.
What are they searching 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 much easier than curing them once established.
Colorado blue spruces occupy 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 symptom. Treatment can halt the fungus from decimating 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 Jefferson County are susceptible 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 dangers 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 initiation for Jefferson County homeowners. The Asian invasive has decimated ash trees across Jefferson County 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 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 skip 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 Jefferson County.
