Tree Care in Hanover, NH

If you're looking at the trees in your Hanover yard and feeling uneasy, you're not imagining things. Many of the mature trees here are now 50 to 60 years old, which is a critical age for the species commonly planted when neighborhoods were built up. You'll see a lot of silver maples and Norway maples from that era. These were chosen because they grow fast, but that speed comes at a cost. Silver maples have notoriously weak wood and aggressive surface roots that can damage foundations and walkways. Norway maples are invasive and create such dense shade that nothing grows beneath them, including your lawn. The real issue is that a tree planted for quick shade decades ago is now a mature asset, or a significant liability, depending on its health and structure.

Why Tree Care Matters in Hanover

Professional tree care here is about managing risk and preserving value. Our cold, humid climate with over 16 storm events a year tests trees constantly. Wind is the primary concern. When our heavy clay soils get saturated from rain, the risk of a tree uprooting increases dramatically. A professional assesses more than just dead branches. We look for included bark unions, which are weak branch attachments that are guaranteed to fail in a heavy, wet snow or an ice storm. For your mature sugar maple or red oak, proper care isn't an expense. It's an investment in protecting your property and maintaining an asset that, when appraised correctly, can add thousands of dollars to your home's value.

Your Tree's History

Most homes in Hanover's established neighborhoods were built from the 1960s through the 1980s. Builders and early homeowners often selected trees for fast growth and instant curb appeal, not for longevity or structural integrity. This is why we see so many Bradford pears, which are beautiful but genetically programmed to split apart after 15-20 years, and silver maples. These trees are now entering their mature decline phase. The problems you see today, like cracking branch unions or heaving sidewalks, were essentially planted 55 years ago. Understanding this history is key to developing a smart management plan for your property.

Active Tree Threats in Grafton 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 Grafton County, NH

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 Grafton County, NH

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.
