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

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 common evidence 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 choice for prompt, responsive tree treatment service in Bethesda! Trained to detect and analyze diseases and insect pests, these tree specialists prescribe treatments for ailments that afflict Wisconsin trees.

Changes in leaf color are another identifier. Yellow leaves can be reflective of a fertilizer shortage, often with oaks. Yet, 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!

Averting 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 Bethesda.

What are they hunting for? The aforementioned symptoms, of course. Another area of note is crevices or cavities in trees, where moisture and insects gather. The goal is to spot existing or possible problems proactively. Blocking a disease or insect infestation is far easier than curing them once established.

Colorado blue spruces occupy many yards. A close inspection, though, might discover evidence of Rhizosphaera needle cast, a fungus that attacks this non-native species. Brown needles, or collected needles beneath a tree, are a giveaway. Treatment can block 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 far more resistance to insects and disease. Concolor firs and Norway spruces are alternatives to Colorado spruces.

Other tree species in Bethesda 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 avoid root rot, an ailment that affects trees growing in wet soil. Root rot isn’t picky, either – its decay affects trees from a multitude 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 goes after birches. Linden borers mostly target lindens. 

The emerald ash borer has been a rude initiation for Bethesda homeowners. The Asian invasive has decimated ash trees across Bethesda 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 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 Bethesda.
