Tree Care in Lewisville, WA

Neighborhood street view in Lewisville, WA — Clark County neighborhood illustration

If you're looking at the trees in your Lewisville yard and feeling concerned, you're not alone. Most of the residential tree problems I see here trace back to a simple fact: the wrong tree was planted in the wrong place 40 to 50 years ago, when these neighborhoods were built. Builders often chose fast-growing species for instant curb appeal, like silver maples for quick shade. While they grew fast, they have weak wood and aggressive surface roots that can damage foundations and sidewalks. We also see a lot of mature Douglas firs and bigleaf maples from the original forest, which are now large and need proper management to stay healthy and safe near your home.

Why Tree Care Matters in Lewisville

Professional tree care here is about protecting a major asset. A mature, healthy tree in Clark County has real, quantifiable value that contributes significantly to your property's worth. We use the industry-standard CTLA method to appraise trees, considering species, size, and condition. More importantly, it's about safety and preservation. Our wet climate, with over 52 inches of rain, promotes fungal issues like Laminated Root Rot in conifers. Proactive care from someone who knows local species and pests can prevent catastrophic failure, preserving your tree's value and protecting your family and property.

Your Tree's History

The era your Lewisville home was built, around 1978, directly explains your tree issues today. The landscaping choices of that time prioritized fast growth and low initial cost. This is why so many properties are now dealing with the consequences of trees like the Bradford pear, which is structurally guaranteed to split after 15 to 20 years, or black locust, which aggressively suckers. These trees are now at peak maturity and showing their inherent weaknesses, requiring careful assessment and often corrective pruning or removal to mitigate safety risks.

Active Tree Threats in Clark County

Laminated Root Rot high

Affects: Douglas fir (primary), grand fir, mountain hemlock - the dominant conifers of the PNW

Soil fungus (Phellinus sulphurascens) that spreads through root contact. Infected trees show reduced growth, thinning crown, and eventually blow over in wind because roots are rotted. Spreads slowly but persistently through stands.

What to do: If a Douglas fir falls or shows lean/crown thinning, have roots assessed. Adjacent trees connected by root contact may also be infected. Stumps of infected trees continue to spread the fungus - consider stump grinding.

Swiss Needle Cast moderate-high

Swiss Needle Cast - active in Clark County, WA

Affects: Douglas fir - the most common tree in PNW landscapes

Fungal disease that causes Douglas fir to shed needles prematurely. Trees look thin and yellow. Fog and moisture promote the fungus. Coastal areas worst affected.

What to do: Improve air circulation through pruning. In severe cases, consider fungicide treatment. May need to diversify away from Douglas fir in heavily affected areas.

Bronze Birch Borer moderate

Bronze Birch Borer - active in Clark County, WA

Affects: European white birch (highly susceptible), paper birch, other birch species

Native beetle that attacks stressed birch trees. Larvae bore under bark, killing branches from top down. European white birch (the popular ornamental) is far more susceptible than native species.

What to do: Keep birch well-watered - drought stress is the #1 trigger. Mulch root zone. Consider replacing European white birch with resistant River Birch or native paper birch.
