Seasonal Tree Care
The Homeowner’s Guide to Fall Tree Health Care in Northern Virginia
Fall has a way of making us notice our trees again. Maples flash red and orange, leaves scatter across the lawn, and that oak outside
Keeping your trees healthy and safe takes more than the occasional pruning. It requires a well-rounded approach that addresses every aspect of their biology, structure, and long-term health. That’s exactly what you get when you work with the professionals at RTEC Treecare.
Some tree companies in the Chantilly area stick to the basics. RTEC Treecare takes a holistic approach, making sure your trees get the support they need from roots to trunk to twigs, staying safe, healthy, and beautiful for years to come.
Picking up a couple of chainsaws and slapping “tree care” on a truck door — pretty low bar. But genuine, science-backed tree care? That requires real education, hands-on experience, proper equipment, and a depth of expertise most companies just don’t have.
If you’re a homeowner or property manager in Chantilly, VA, that’s never been something you had to worry about. RTEC Treecare has been providing award-winning tree care services in the Chantilly, VA area for over 30 years. We know trees inside and out — and we understand the specific environmental conditions of the Mid-Atlantic region that directly impact tree health.

Our yard is at 2828 Mary St in Falls Church, roughly 12 miles east of Chantilly. The usual run is I-66 to Route 50 and out Stringfellow, and it takes a little over 20 minutes when traffic cooperates.
Short drives make the boring parts of tree work easier. You get an arborist on site quickly instead of two weeks out. Storm calls get answered by a crew that's already close. Follow up visits, the ones nobody thinks about until they need one, don't turn into a production. That's most of what proximity actually buys you.
The name goes back to the Chantilly plantation, established here in the early 1800s. Almost none of that survives. The mansion was destroyed during the Civil War and only a stone outbuilding still stands near Route 50.
What matters for your trees is what got built here since, and it came in two distinct waves. Levitt and Sons put up the more than 1,900 homes of Greenbriar in the late 1960s and early 1970s. Then, after 1980, developers filled in the farmland south of Dulles with subdivision after subdivision.
The older canopy that did survive is mostly in parks now. Ellanor C. Lawrence Park holds 650 acres of forest, stream and meadow off Walney Road, and Sully Historic Site preserves buildings put up between 1794 and 1801. Those are the reference points for what this land looked like before the subdivisions.
Those two waves produced two completely different canopies inside the same ZIP code. Greenbriar's landscape trees are now 55 years old or more, planted as saplings in tract yards and never really meant to get this big. The post-1980 neighborhoods are running 20 to 40 years behind that, with trees just now reaching the size where structure starts to matter.
An older Greenbriar tree and a newer Chantilly tree fail in almost opposite ways, so they need almost opposite work.
Trees in the 55 year range are past the point where you're shaping anything. They're carrying decay in old wounds, dropping deadwood out of the upper canopy, and often standing over a house that was built when they were four feet tall. On these we're looking for hazards and buying safe years, not improving form.
Younger trees are the ones you can still fix cheaply. A codominant stem corrected at 20 years is a fifteen minute cut. The same defect at 50 years is a cabling job or a removal.
Then there's the construction problem, which Chantilly has more of than most places. Additions, driveway widenings, patios and utility trenches all happen inside root zones, and trees don't complain about it right away. A root system cut during a project in 2023 shows up as a thinning canopy in 2026, long after anyone connects the two. Fairfax County's own construction standards require protection fencing at the limits of clearing and mapping of critical root zones for trees 12 inches and larger, which tells you how seriously the county takes it. If you're planning work near a tree you want to keep, the time to involve an arborist is before the equipment shows up.
Our crews run Chantilly routes regularly and drive past their own work on the way to the next job. In neighborhoods where the houses were all built by the same company on the same street grid, a bad removal or a rutted lawn is extremely visible. We'd rather be the outfit your neighbor points to than the one they warn you about.
