Are all ash trees in Newark at risk from EAB?

Yes — EAB is established in all Newark zip codes. All three ash species (white, green, and black ash) are equally susceptible. If you have ash trees that are otherwise healthy, treatment with a systemic imidacloprid or emamectin benzoate trunk injection is effective if started before significant infestation. Contact us for a free EAB assessment.

My flowering dogwood in Newark has dark spots and brown edges on the leaves — what is it?

Leaf spots and brown edges on dogwoods in Newark are typically dogwood anthracnose (Discula destructiva), a fungal disease that's particularly severe in cool, wet springs. It can be managed with timed fungicide applications but requires treatment before new leaf emergence in spring. Trees with multiple years of severe infection may develop stem cankers that require removal of affected branches.

Is spotted lanternfly killing Newark's trees?

Spotted lanternfly weakens trees significantly through repeated feeding but rarely kills mature, established trees outright. The primary concern is cumulative stress over multiple seasons reducing tree vigor and increasing susceptibility to secondary pests and diseases. Young trees and highly stressed trees are at greater risk. Management focuses on reducing the local population density, particularly by removing tree-of-heaven host plants.

How do I tell if my Newark oak has oak wilt?

Oak wilt manifests differently in red oaks versus white oaks. In red oaks, expect rapid leaf wilt and browning from the top down, often killing the entire tree within a single growing season. In white oaks, decline is slower — individual branches die progressively over 1–3 years. If you suspect oak wilt, have it confirmed before any pruning — pruning wounds in spring and early summer are primary infection entry points.

Newark's tree health concerns center on EAB in its white and green ash population, spotted lanternfly in tree-of-heaven along disturbed corridors near UD and Route 1, and the anthracnose and powdery mildew infections that follow Newark's wet spring weather in its older residential tree canopy.

How It Works

Tree Health & Disease Treatment Process in Newark

Health Assessment

We examine canopy density, bark condition, root collar, branch structure, and soil conditions. Signs like thinning canopy from the top down, S-shaped tunnels under bark, or unusual leaf drop all point to specific problems that require different responses.
Diagnosis

We identify the specific pest or disease and assess how far it has progressed. Some conditions — early-stage EAB, certain fungal infections — are treatable if caught in time. Others have passed the point where treatment is cost-effective versus removal.
Treatment Plan

For treatable conditions, we develop a prescription that may include systemic insecticide trunk injection, fungicide application, targeted pruning to remove diseased material, or soil fertility programs to strengthen root systems.
Follow-Up

Treatment programs require monitoring. We schedule follow-up assessments to evaluate response and adjust the program if needed. Some treatments (like EAB injections) need to be renewed on a 2–3 year cycle to maintain protection.

Local Tip for Newark Homeowners

Newark's wet springs — above Delaware's average precipitation from March through May — create prime conditions for anthracnose, powdery mildew, and other fungal infections in dogwoods, sycamores, and maples. Preventive fungicide timing in late March is critical; reactive treatment after symptoms appear is much less effective.
