Tree Care in Highwood, IL

If you're looking at a large, mature tree in your Highwood yard and wondering about its health, you're not alone. Most homes here were built around 1959, which means the trees are now about 67 years old. That's the age when many common builder-planted species, like silver maple and Siberian elm, begin to show serious structural problems. Their fast growth decades ago provided quick shade, but weak wood and aggressive roots are now liabilities. Our cool-humid climate with 39.5 inches of annual rain and 18.9 storm events a year tests these aging giants. A professional assessment is crucial because you can't see decay from the outside. Problems often start internally years before any visible symptom appears.

Why Tree Care Matters in Highwood

Professional tree care in Highwood is about managing inherited risk. The wrong tree in the wrong place from 60 years ago is now a mature asset or a significant hazard over your home. Our specific pest threats, like the guaranteed Emerald Ash Borer for any remaining ash trees, require proactive management. Different storm types cause different failures. Sustained winds followed by a sudden shift, common here, can fatigue weak branch unions until they fail. A certified arborist uses tools like sounding with a mallet to listen for hollow tones inside the trunk, identifying decay long before a cavity opens up. This isn't just maintenance. It's protecting your property from predictable, costly damage.

Your Tree's History

The 1940s to 1960s building boom prioritized fast growth for instant curb appeal. In Highwood, this legacy is visible in every other yard. Builders favored species like silver maple for its speed and green ash for its toughness. Now, these trees are at the end of their functional lifespan in an urban setting. Silver maples develop included bark and weak unions, making large limbs prone to splitting. Every green ash is dead or dying from Emerald Ash Borer. The good news is that native species planted in that era, like the occasional bur oak or sugar maple, are often the healthiest, most valuable trees on the property today.

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.
