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

Trees, like people and animals, get ill. How do you locate a “tree doctor” if your trees show signs of poor health?

Leaf loss, in one area or across a tree’s entire crown, is the most usual sign 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 Ottawa! Educated to recognize and diagnose diseases and insect pests, these tree specialists prescribe treatments for ailments that affect Wisconsin trees.

Changes in leaf color are another red flag. Yellow leaves can be symptomatic of a fertilizer shortage, 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 Ottawa.

What are they searching 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 identify existing or potential problems early. Blocking a disease or insect infestation is much easier than curing them once established.

Colorado blue spruces fill many yards. A close look, though, might find proof 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 lovely 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 substitutes for Colorado spruces.

Other tree species in Ottawa are vulnerable 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 afflicts trees growing in wet soil. Root rot isn’t choosy, 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 lethal bronze birch borer attacks birches. Linden borers mostly target lindens. 

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

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 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 Ottawa.
