Tree Care in Glen Ellyn, IL

If you're looking at the trees in your Glen Ellyn yard and feeling uneasy, you're not imagining things. Many of the mature trees here are now 50 to 60 years old, which is a critical lifespan point for several common problem species. Builders in the 1970s often planted fast-growing trees like silver maple for quick shade, but their weak wood and aggressive surface roots are now causing property damage. Similarly, the once-popular green ash tree, which lines many streets, is now a standing hazard due to the Emerald Ash Borer. The good news is that your native trees, like the stately bur oak and sugar maple, are built for our DuPage County climate and, with proper care, can be the lasting assets they were meant to be.

Why Tree Care Matters in Glen Ellyn

Professional tree care here is about risk management and asset protection. Our local storm pattern of 23 events per year, including high winds that can shift direction suddenly, puts immense stress on mature trees with hidden flaws. A certified arborist doesn't just trim branches; they identify structural weaknesses like included bark in maples or root plate issues in saturated clay soils. Furthermore, your mature trees have significant property value. We use the industry-standard CTLA method to appraise them, considering species, size, and health. Proactive care preserves that value and prevents costly emergency removals or property damage from failures.

Your Tree's History

The era your home was built, primarily the 1960s through 1980s, directly explains your current tree issues. This was the peak planting time for the problem species we now manage. Landscapers favored fast-growing trees for new subdivisions, selecting silver maples for quick shade and Bradford pears for spring flowers, without regard for their poor long-term structure. These trees are now entering their decline phase. Combined with the arrival of pests like the Emerald Ash Borer, which has decimated ash trees planted in that era, many properties are facing a perfect storm of aging, unsuitable trees that require professional assessment and action.

Active Tree Threats in DuPage County

Emerald Ash Borer (EAB) critical

Affects: All ash species (Fraxinus) - green, white, black, blue ash

Metallic green beetle native to Asia. Larvae feed under bark, cutting off water and nutrient transport. Tree dies within 2-5 years of infestation. Has killed hundreds of millions of ash trees in North America since 2002.

What to do: Remove dead standing ash trees immediately - they become brittle hazards within 1-2 years. Preventive trunk injection (emamectin benzoate) can save high-value ash but requires biannual treatment.

Spotted Lanternfly high

Spotted Lanternfly - active in DuPage County, IL

Affects: Tree of Heaven (primary host), but feeds on 70+ species including maples, oaks, walnut, willow, birch, grape

Showy planthopper from Asia. Feeds on sap, excretes honeydew that promotes sooty mold. Doesn't usually kill trees directly but weakens them and creates a mess. Major agricultural pest on grapes and orchards.

What to do: Destroy egg masses (gray mud-like patches on any flat surface) October-June. Remove Tree of Heaven from property to eliminate breeding host. Report sightings to state agriculture department.

Oak Wilt high

Affects: Red oak group (red, pin, scarlet, black - usually fatal). White oak group (white, bur, swamp white - slower, sometimes survivable).

Fungal disease (Ceratocystis fagacearum) that clogs water-conducting vessels. Red oaks can die within weeks. Spreads through connected root systems between nearby oaks and via beetles attracted to fresh wounds.

What to do: NEVER prune oaks between April and October - beetles carry the fungus to fresh cuts. If an oak shows sudden wilting/browning, get a certified arborist assessment immediately. Root barriers can prevent spread between adjacent trees.
