Tree Care in Lexington, MA

If you're looking at the trees in your Lexington yard and wondering about their health, you're not alone. Most of the problems we see here, from cracked sidewalks to storm-damaged limbs, trace back to a simple fact: the wrong tree was planted in the wrong place decades ago. Builders in the 1960s and 70s often chose fast-growing species for quick shade and curb appeal. That's why you see so many silver maples, known for their weak wood and aggressive surface roots, and Bradford pears, which are practically guaranteed to split apart after 15 to 20 years. These trees are now mature and showing their age, which means they need a professional eye. You can't see inside a tree from the outside. Issues like internal decay can start years before any external symptom, like a fungus or a crack, becomes visible to you.

Why Tree Care Matters in Lexington

Professional tree care in Lexington is about managing risk and preserving value. Our local storms, averaging over 34 per year, test trees in specific ways. Wind primarily causes uprooting when our clay soils are saturated, and it targets weak branch unions, which are common in those legacy Bradford pears and silver maples. The most dangerous pattern is a sustained wind from one direction followed by a sudden shift, which fatigues the tree's structure. A certified arborist uses tools and techniques, like sounding the trunk with a mallet to check for hollow spots, to assess these hidden risks. This proactive care protects your home, your family, and the significant investment your mature trees represent.

Your Tree's History

The age of your home is a strong clue to your tree's problems. With Lexington's housing stock largely built in the 1960s, your trees are likely around 60 years old. This was an era of rapid development where landscaping choices prioritized speed and cost. Norway maples were planted everywhere for their toughness, but they're now invasive and crowd out our native oaks and sugar maples. The silver maples and Bradford pears planted for instant gratification are now in the final third of their lifespan, where structural weaknesses become critical. Understanding this history helps us diagnose why a tree is failing and plan for its replacement with a species better suited for the long term.

Active Tree Threats in Middlesex 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 Middlesex County, MA

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 Middlesex County, MA

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.

Hiring a Tree Service in Lexington

With nearly a thousand landscaping companies in Middlesex County, choosing the right one is critical. Always hire a certified arborist who is insured. Ask specifically about their experience with our common local issues: managing Emerald Ash Borer in ash trees, identifying the early signs of oak wilt, and safely dismantling large, failing silver maples or Bradford pears. A true professional will provide a detailed, written estimate and never recommend topping a tree, which is harmful and outdated practice.
