Tree Care in Tarrytown, NY

If you're looking at a large, mature tree in your Tarrytown yard, it was likely planted when your home was built around 1957. That means it's about 69 years old and has seen a lot of our local weather. Many of the problems we see today trace back to the original landscaping choices. Builders often chose fast-growing trees for quick shade and curb appeal, like silver maples and Bradford pears. Silver maples have weak wood and aggressive surface roots that can damage walkways. Bradford pears are beautiful but have a fatal flaw: their branch structure is so poor they are almost guaranteed to split apart after 15 to 20 years. These trees are now mature and showing the weaknesses of those initial decisions.

Why Tree Care Matters in Tarrytown

Professional tree care here is about managing risk and preserving value. With over 13 storm events a year and our 51 inches of annual rainfall, soils get saturated. That's when mature trees with compromised root systems are most likely to uproot. You can't see inside a tree from the outside. Internal decay can be advanced long before a cavity appears. We use tools like sounding, tapping the trunk with a mallet to listen for the dull thud of rot versus the solid ring of healthy wood, to assess hidden problems. It's preventative maintenance for your largest, most valuable landscape assets and your family's safety.

Your Tree's History

The 1940s to 1960s building boom in Westchester favored instant landscaping. Norway maples were popular for their fast growth and tolerance, but they're now invasive and crowd out our native oaks and sugar maples. The silver maples and Bradford pears from that era are now at the end of their typical lifespan and are failing. This means many Tarrytown properties have legacy trees that are oversized for their lots, structurally unsound, or damaging hardscapes. Your tree issues are likely a direct result of its species and its age, not neglect.

Active Tree Threats in Westchester 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 Westchester County, NY

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 Westchester County, NY

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.
