Tree Challenges in Western DuPage County

​

Development-Era Canopy Reaching Maturity

Much of western DuPage was developed in waves: post-war subdivisions in the 1950s-60s, a second wave in the 1970s-80s, and continued growth through the 2000s. The trees planted during these eras are now entering their mature and over-mature phases. Norway and silver maples from the 1960s are developing structural problems and declining health. Pin oaks planted throughout the 1970s-80s are showing chronic chlorosis. The "builder-grade" trees used in 1990s-2000s developments — Bradford pears, autumn blaze maples, and green ash — are failing at high rates due to inherent species weaknesses and emerald ash borer. These communities need a transition strategy: proactive replacement of declining species with better-adapted selections, while preserving the healthy specimens that anchor the canopy.

​

Soil Variability

Western DuPage sits on the Valparaiso Moraine, and soil conditions vary more dramatically over short distances than in most suburban areas. A property in Warrenville might have well-drained gravelly soil, while a lot a mile away in Winfield sits on heavy, poorly-drained clay. This variability means species selection and soil management must be site-specific. Cookie-cutter approaches to tree planting and PHC don't work here — what thrives on one property may struggle on another a block away.

​

Storm Exposure

Western DuPage has less building density to buffer severe weather compared to communities closer to the city. When derecho-level wind events come through — as they periodically do — trees with unmanaged structural defects fail at much higher rates. Proactive structural pruning, especially end-weight reduction on long lateral limbs and crown reduction on top-heavy trees, dramatically reduces storm damage risk. We've seen this pattern repeatedly: managed trees withstand events that destroy their unmanaged neighbors.

​

Illinois Prairie Path Adjacency

Properties bordering the Illinois Prairie Path face particular tree management considerations. Trees overhanging the path require clearance maintenance. Invasive species like buckthorn colonize path-adjacent edges and compete with desirable landscape trees. The ecological interface between the path corridor and private properties creates management opportunities — homeowners can extend the conservation value of the path by planting native species and managing invasives on their own land.

Frequently Asked Questions — Western DuPage County

​

All of the ash trees on our block in Wheaton died. What should we plant to replace them?

The best approach is to diversify — don't replace ash monoculture with another monoculture. A good strategy mixes species: swamp white oak and bur oak for long-lived canopy trees, Kentucky coffeetree or hackberry for tough, adaptable shade, and tulip tree or American linden for faster initial growth. Avoid autumn blaze maple (overplanted, brittle wood) and Bradford pear (splits apart, now illegal to sell in several states). We assess your specific site conditions — soil, drainage, sun exposure, overhead utilities, and available growing space — and recommend a mix that creates a resilient, diverse canopy rather than a single-species gamble.

​

Is the Morton Arboretum affiliated with local tree care companies?

No — the Morton Arboretum is a research and education institution that doesn't endorse or affiliate with private tree care companies. However, their research on species adaptation, pest management, and urban forestry best practices directly informs our work. We stay current with Arboretum publications and attend their professional education programs. When a client asks "what tree should I plant?" our recommendations incorporate Morton Arboretum trial data on which species perform best in our region's conditions.

​

We have a tree growing into our fence line with the neighbor. Who is responsible?

In Illinois, you have the right to trim branches and roots that cross onto your property, up to the property line. Your neighbor has the same right on their side. Neither party can damage or kill the tree in the process. For trees directly on the property line (true boundary trees), both property owners share ownership and both must agree before removal. Our recommendation: get a professional assessment, communicate the findings to your neighbor, and try to reach agreement on a management plan. Most neighbor tree disputes can be resolved with good information and good communication.

​

Our landscape company says our trees need "deep root feeding." Is that necessary?

"Deep root feeding" — soil injection of liquid fertilizer — can be beneficial in specific situations, but it's not the universal treatment it's often sold as. Fertilization should be based on a soil test showing actual nutrient deficiencies, not applied on a calendar schedule regardless of need. Over-fertilization can actually harm trees by promoting excessive growth at the expense of structural integrity. We test first, then recommend treatments based on what your trees actually need. Sometimes the answer is fertilization. Often the answer is improved soil conditions, proper mulching, or addressing a drainage issue — interventions that have longer-lasting effects.
