Tree Care in New London, NH

If you're looking at the trees around your New London home and feeling uneasy, there's a good reason. Many of the properties here were built in the late 1950s, meaning the trees are now about 67 years old. That's when fast-growing species planted for instant shade, like silver maple and Norway maple, reach a critical age of decline. Their weak wood and aggressive roots become a real liability. Our cold-humid climate, with 10 storm events a year, tests these mature trees constantly. Wind doesn't just break branches. Sustained wind from one direction followed by a sudden shift fatigues the entire structure, making failures more likely.

Why Tree Care Matters in New London

Professional tree care here isn't just about aesthetics. It's about risk management specific to our 5b hardiness zone and mature landscape. You can't see decay inside a trunk from the outside. Problems like included bark in a Bradford pear or internal rot in an old silver maple often show symptoms years after they start. A certified arborist uses tools like sounding, tapping the trunk to listen for the dull thud of decay versus the ring of solid wood, to assess the true hazard. With pests like Emerald Ash Borer confirmed in New Hampshire, proactive inspection and care are your best defense for protecting your property's value and safety.

Your Tree's History

The 1940s to 1960s building boom defined our local tree issues. Builders and homeowners favored trees that grew quickly. Now, decades later, we're dealing with the consequences. The Bradford pear planted for its spring blossoms is almost guaranteed to split apart due to its poor structure. The Norway maple, once popular, now outcompetes our native sugar maples and red oaks. These choices made sense then but created predictable problems we must manage today on properties throughout Merrimack County.

Active Tree Threats in Merrimack 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 Merrimack 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 Merrimack 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.
