Tree Care in Fontana-on-Geneva Lake, WI

If you're looking at the trees in your Fontana yard and feeling uneasy, you're not imagining it. Many of the mature trees here, planted when these lake homes were built in the late 1970s, are now at a critical age. Builders often chose fast-growing species like silver maple for quick shade, but its weak wood and aggressive roots are now causing problems. The same is true for Siberian elm, another common choice that's prone to storm damage and disease. My job is to help you understand which trees are assets and which have become liabilities, so you can protect your property and the lake's beauty.

Why Tree Care Matters in Fontana-on-Geneva Lake

Professional tree care here is about risk management and value preservation. With about 12 significant storm events a year, and our soils getting saturated from lake-effect moisture, the wrong tree in the wrong place is a genuine hazard. A mature, healthy bur oak or sugar maple adds substantial value to your property, assessed using industry-standard methods that consider species, size, and condition. Conversely, a declining ash tree, which is almost certainly infested with Emerald Ash Borer, is a depreciating asset and a safety threat that needs proactive management.

Your Tree's History

The landscaping from the 1970s and 80s development boom is now the source of most tree issues. The philosophy was often 'fast and full,' leading to the widespread planting of species we now know are problematic. Silver maples were planted too close to homes and driveways, and their structural flaws are showing. Many green and white ash trees were also planted during this era, and they are now succumbing to Emerald Ash Borer. We're essentially dealing with the expiration date of those original landscaping decisions.

Active Tree Threats in Walworth 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 Walworth County, WI

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 Walworth County, WI

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.
