EAB has killed hundreds of millions of ash trees across North America, and it’s still active throughout Michigan. If you have ash trees on your property, a preventative treatment program is the single most effective step you can take to protect your trees. We use soil drenches and trunk injections to protect ash trees before the beetle gets a foothold.

EAB is not the only insect that threatens Michigan’s trees. Japanese beetles, bagworms, scale insects, and several boring beetles can also cause serious damage to ornamental and shade trees across the region. We use targeted treatments to knock back active infestations and preventative programs to protect trees before populations get out of hand.

Oak wilt is one of the most destructive tree diseases in Michigan. Red oaks are especially vulnerable and can die within weeks of infection. We treat affected trees with fungicide injections and offer root pruning services to help prevent the disease from spreading to healthy oaks through root grafts.

Spotted lanternfly has been moving steadily into Michigan and poses a real threat to fruit trees, maples, and other species. We monitor for early signs of infestation and can apply treatments to protect high-value trees if the pest is detected on your property.

Apple scab, anthracnose, fire blight, and Diplodia tip blight are among the most common diseases we diagnose in Southeast Michigan. Treatment timing matters a lot with fungal diseases in particular, so early identification is key. We use fungicide programs and, where appropriate, pruning to remove infected tissue.

Compacted soil is one of the most common and overlooked problems affecting urban trees. When soil is too dense, roots can’t access water, oxygen, or nutrients. Vertical mulching and air spading break up compacted soil around the root zone without damaging roots in the process.

Suburban trees don’t have access to the nutrient cycling that keeps forest trees healthy. Deep root fertilization delivers a slow-release nutrient blend directly into the root zone, bypassing the compacted surface layer and giving trees what they need through the growing season.

Mycorrhizal fungi form a symbiotic relationship with tree roots and dramatically increase their ability to absorb water and nutrients. Newly planted trees and trees in disturbed soils may lack these fungi entirely. We apply mycorrhizal inoculants directly to the root zone to help trees remain healthy over the long-term.

Broadleaf evergreens like holly, rhododendron, and boxwood are prone to winter burn in Michigan, where dry, cold winds pull moisture out of leaves faster than frozen roots can replace it. Anti-desiccant sprays applied in late fall create a protective coating that reduces moisture loss through the winter months.

Applied in late winter before buds break, dormant oil smothers overwintering eggs and insects on the bark and branches of trees and shrubs. It’s a low-impact treatment that can significantly reduce pest pressure and prevent the associated damage they cause before the growing season even starts.

Trees planted too deeply, or those that have accumulated soil and mulch around their base over the years, often develop girdling roots that slowly strangle the trunk. Root collar excavation removes that excess material, exposes the root flare, and corrects the grade around the tree before permanent damage sets in.

Growth regulators slow the above-ground growth of a tree and redirect its energy toward the roots instead. The result is a denser, more extensive root system that makes trees more drought-tolerant and better equipped to fight off pests and disease. We commonly recommend growth regulator treatments to combat stress and reduce pruning requirements.
