Tree Care in Lake Forest, IL

Neighborhood street view in Lake Forest, IL — Lake County neighborhood illustration

If you're looking at the mature trees on your Lake Forest property, you're likely seeing the legacy of the 1970s building boom. Many of the homes here were built around 1976, and the landscaping choices made then are the problems we manage today. Builders often selected fast-growing trees for quick shade and curb appeal, planting species like silver maple and Siberian elm that are now 50 years old and showing their weaknesses. Silver maples have aggressive surface roots that can damage foundations and weak wood prone to storm failure, while Siberian elms are brittle and messy. Understanding this history is the first step to protecting your property's value and safety.

Why Tree Care Matters in Lake Forest

Professional tree care here isn't just about aesthetics; it's about risk management and asset protection. Our cool-humid climate with 18.9 storm events a year means mature trees face regular stress from wind and saturated soils, which can lead to uprooting or branch failure. A certified arborist assesses trees using methods like the Council of Tree and Landscape Appraisers (CTLA) standard, quantifying their value and your liability. Proactive care for native species like your bur oaks and sugar maples preserves significant property value, while managing threats like the invasive Emerald Ash Borer, which has devastated our local ash population, is a critical safety and financial necessity.

Your Tree's History

The 1960s to 1980s development era directly explains most of the tree issues we see in Lake Forest today. The preference for fast-growing trees created a ticking clock. A Bradford pear, for example, is practically guaranteed to split at its weak, included bark unions after 15 to 20 years, and many from that era are now failing. Similarly, the widespread planting of green ash for its hardiness has backfired spectacularly with the arrival of Emerald Ash Borer. We're now at the point where these builder-selected trees have reached the end of their structural lifespan, requiring careful assessment and often removal or major structural pruning.

Bur Oak

Toughest native oak - drought, cold, and wind tolerant. Massive specimens

Sugar Maple

Fall color champion, syrup production, but salt-sensitive along roads

White Birch (Paper Birch)

Excellent shade, fragrant flowers, attracts pollinators

Active Tree Threats in Lake 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 Lake 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.
