If Your Trees Look Ill, Don’t Wait to Summon a “Tree Doctor” in Delafield!

Trees, like people and animals, get sick. How do you reach a “tree doctor” if your trees show symptoms 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, 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 top bet for prompt, responsive tree treatment service in Delafield! Trained to spot and analyze diseases and insect pests, these tree specialists prescribe remedies for ailments that affect Wisconsin trees.

Changes in leaf color are another red flag. Yellow leaves can be reflective of a fertilizer deficit, 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 interpret the messages of leaf colors!

Preventing problems is the most effective 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 Delafield.

What are they hunting 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 identify existing or potential problems early. Avoiding a disease or insect infestation is far easier than curing them once established.

Colorado blue spruces occupy many yards. A close inspection, though, might find signs of Rhizosphaera needle cast, a fungus that attacks this non-native species. Brown needles, or piles of needles beneath a tree, are a giveaway. Treatment can thwart the fungus from decimating and eventually killing these lovely trees.

Another option – 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 alternatives to Colorado spruces.

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

Application of fungicides can prevent root rot, a condition that afflicts 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 lethal bronze birch borer goes after birches. Linden borers mostly target lindens. 

The emerald ash borer has been an unwelcome initiation for Delafield homeowners. The Asian invasive has decimated ash trees across Delafield 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.

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 miss seeing a doctor for years on end, don’t gamble with the well-being of your trees. Contact Dorshak Tree Specialists for a complimentary checkup. Yes, their “tree doctors” still make house calls to Delafield.
