Tree Care in Deerfield, IL

If you're looking at the trees in your Deerfield yard and feeling uneasy, there's a good reason. Many of the mature trees here, like the silver maples and Bradford pears, were planted when these homes were built in the late 1960s and 70s. Builders chose them for fast growth and instant shade, but they come with built-in problems. Silver maples have weak wood and aggressive surface roots that can damage foundations and sidewalks. Bradford pears are practically guaranteed to split at their weak branch unions after 15 to 20 years. Now, at over 50 years old, these trees are entering a high-risk phase where storm damage and structural failure become much more likely.

Why Tree Care Matters in Deerfield

Professional tree care here isn't just about aesthetics. It's about risk management and protecting your property's value. Our cool-humid climate and nearly 19 storm events a year create a perfect storm for tree failure. Wind events, especially after our 32 inches of annual rain saturates the soil, can cause mature trees with poor root systems to uproot. A certified arborist assesses trees using industry standards like the CTLA method, which quantifies a tree's value and its potential liability. For ash trees, proactive treatment or removal for Emerald Ash Borer is a critical financial decision, not just a landscaping one.

Your Tree's History

The tree issues you're dealing with today were decided when your home was built. The 1960s to 1980s development boom favored fast-growing, inexpensive species to quickly landscape new subdivisions. This means many Deerfield properties are now home to aging silver maples, Siberian elms, and green ash trees, all of which are prone to failure. These trees are now 50 to 60 years old, which is the natural lifespan for many of these problem species. You're not seeing poor health, you're seeing the predictable decline of the wrong tree planted in the wrong place decades ago.

Active Tree Threats in Lake County

Emerald Ash Borer (EAB) critical

Emerald Ash Borer (EAB)

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

Oak Wilt  -  active in Lake County, IL

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.
