Tree Care in Highland Park, IL

If you're looking at the trees in your Highland Park yard, you're likely seeing the legacy of the 1960s building boom. Many of the silver maples and Bradford pears planted back then are now mature, and that's where problems start. Builders chose these species for fast growth and instant curb appeal, but silver maple has weak wood and aggressive surface roots, while a Bradford pear is practically guaranteed to split at its weak branch unions after 15 to 20 years. These structural flaws aren't always visible from the outside. Internal decay can be active for years before a cavity or crack appears. That's why we use tools like sounding, tapping the trunk with a mallet to listen for the dull thud of rot versus the clear ring of solid wood. It's a simple way to assess what you can't see.

Why Tree Care Matters in Highland Park

Professional tree care here is about managing inherited risk and protecting your property's value. With nearly 19 storm events a year in Lake County, weak trees are a liability. Our specific wind patterns are particularly dangerous. Sustained winds from one direction, common with lake-effect weather, fatigue a tree's root system. A sudden wind shift after that can cause catastrophic failure, either uprooting the whole tree in our often-saturated clay soils or tearing out large limbs. Proactive care from someone who knows local species and conditions prevents these failures. It's not just about beauty. It's about safety and preserving the mature canopy that defines our neighborhoods.

Your Tree's History

The age of your home is a strong indicator of your tree's problems. Most Highland Park homes were built around 1963, meaning the landscaping is roughly 63 years old. The popular choices from that 1960s to 1980s era are now declining. Fast-growing silver maples are prone to storm damage. Siberian elms are a mess. The green and white ash trees, which were also widely planted, are now dead or dying from the emerald ash borer. This means many properties have reached a critical point where the original landscape trees require major intervention, removal, or replacement with more suitable native species like bur oak or sugar maple.

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.
