Tree Trimming & Pruning in Port Washington, NY

If you're looking at a mature tree in Port Washington, you're likely looking at a decision made in the 1950s. Many of the original builders here chose trees for speed, not longevity. That's why you see so many silver maples and Bradford pears. A silver maple grows fast and gives quick shade, but its weak wood and aggressive surface roots cause constant problems. A Bradford pear looks perfect for about 15 years, then its tight branch structure is almost guaranteed to split in a storm. The challenge is that a tree can look healthy on the outside while decay is hollowing it out from within. We use simple tools like a mallet to sound the trunk; solid wood rings clear, while decayed wood sounds dull. This tells us what's happening inside long before a branch fails.

What Type of Pruning Do Your Trees Need?

What NOT to Do

Never "top" a tree (cutting all branches back to stubs). Topping destroys the tree's structure, causes rapid weak regrowth, and creates a more dangerous tree than you started with. Any company that recommends topping isn't worth hiring.

Active Tree Threats in Nassau 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 Nassau 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 Nassau 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.

What 1940s-1960s-Era Trees Need in 2026

1940s-1960s Homes (65-85 years old trees)
