Herndon is an incorporated town, not just an address inside Fairfax County, and that has practical consequences for anyone maintaining a lawn here. The town runs its own public works department, its own collection schedule, its own vacuum leaf program and its own urban forester. Contractors who treat Herndon as generic Fairfax County get the yard waste wrong, and the homeowner is the one who finds a rejected pile at the curb.
Pro-Mow has worked this part of Northern Virginia as a family owned business for over 35 years, and we set our Herndon service around the town’s calendar rather than the county’s.
Yard waste goes out on your trash day. Town crews collect it weekly. It has to be in reusable sturdy plastic or metal containers of no more than fifty gallons and no more than fifty pounds loaded, and those containers should be marked “Yard Waste.” Thirty gallon paper yard and leaf bags are also accepted. Grass cuttings, weeds, leaves, shrub clippings, twigs and small branches all count.
Brush is bundled separately. Bundles no longer than four feet and no heavier than fifty pounds, with trunk and limb material no more than three inches in diameter. Material cut by tree companies or contractors is not collected by the town, which is worth knowing before you have anything large taken down.
Vacuum leaf collection runs October into December, through the second week, and the schedule alternates between the areas north and south of the W&OD Trail. Leaves go to the usual collection area as close to the curb as possible without blocking storm drains, sidewalks or mailboxes.
We work inside all of that. Our default is to leave clippings on the lawn where growth allows, since they break down within days and return nitrogen to the soil, which also keeps your fifty pound container limit free for the material that genuinely has to go. When we do bag, we bag to a standard the town will actually collect.
Herndon has been a certified Tree City USA community for well over thirty consecutive years, and it shows in the older streets. The town employs an urban forester, enforces tree preservation during development, and requires a permit for removing healthy trees within Resource Protection Areas on private property.
For lawn care that means two things. First, the mature canopy across in-town Herndon produces a real autumn leaf volume and a real amount of shade, and both have to be planned for rather than absorbed. Second, if a tree on your property is causing a lawn problem, removal is not necessarily a decision you can make unilaterally. Check before you commit to a plan that depends on it.
In-town lots. Smaller, older, often with large trees close to the house. Turf here is shade limited, the soil has been in place a long time, and the detail work, edges, trimmed perimeters, bed shapes, accounts for most of the visible quality because there is not much open lawn.
Larger established properties on the edges. More open turf, more mowing time, and a different set of problems centered on compaction and summer stress rather than shade.
We quote them differently because they are different jobs.
Grass areas are cut every seven days, on a fixed day, at a height suited to the cool season grasses grown here and adjusted for how much light each area gets. Mowing on a consistent rhythm promotes lateral shoot growth, producing thicker, denser grass that spreads to cover bare spots. A dense stand helps choke out weeds and reduces soil erosion naturally.
Every visit also covers string trimming in the spots a deck cannot reach, edging along curbs and sidewalks, and clearing clippings with a blower.
Schedule. Same day each week. Weather delays move us to the next business day, Saturday included, and the following week returns to your regular day provided at least four days separate the visits. If you have an irrigation system, set it to stay off in the twenty four hours before your service day. Weekly mowing has clear benefits, but the interval should flex with growth, weather and season rather than run to the calendar regardless.
Every Herndon homeowner has seen the same thing: grass that grows thick in one part of the yard and thin in another. That is usually uneven nutrient availability, because soil varies across a lot in ways nothing on the surface reveals. Fertilization evens it out.
No package has fewer than five visits, and they sit six to eight weeks apart so that slow release product is always working rather than arriving in bursts.
Work starts in late winter. Somewhere between February and mid April a blended feed goes down for green up and root development, carrying a pre-emergent against crabgrass and the grassy weeds that germinate first. Through April, May and June a second application continues slow release nutrition and refreshes the pre-emergent barrier. High summer is handled differently: the July or August visit is an inspection and a weed control service rather than a feed, and it doubles as the assessment of whether the lawn needs aeration in the fall. Once September arrives we go back to feeding, this time with slow and fast release product together, since the lawn needs both an immediate response and a sustained one after summer. The season closes in November or December with a blend aimed at roots, which is the reason a properly fed lawn greens up earlier than its neighbors.
Basic Care is that five visit schedule. Basic Care Plus takes it to seven with a lime application between June and September, which earns its place on in-town lots where fifty years of leaf litter under a mature canopy has steadily acidified the soil, and a grub preventative between April and early June. Premium Care is the eight visit program and carries core aeration and overseeding inside it.
All products are phosphorus free. Every visit leaves an information bulletin and a small yard sign, and we will return between scheduled services if something about the lawn concerns you.
Herndon’s clay soil compacts easily, and compaction restricts root development while blocking water and nutrient movement. Core aeration addresses it directly: plugs of soil and thatch are pulled from the lawn and left on the surface, where within about two weeks they break down back into the root zone as nutrients, while the holes they leave open the soil.
Overseeding follows into those holes. We prepare the lawn for proper seed to soil contact, use equipment suited to the site and select seed matched to Northern Virginia’s climate and soil, meeting National Seed Association standards. A seed starter is included with the service, which gives new seedlings the best chance at germination and lasting establishment.
Early fall is the window. On shaded in-town lots this needs to be an annual job rather than an occasional one.
Mulch. Premium double shredded hardwood in black, brown or natural, at a uniform two and a half inch depth. Beds are cleared of weeds, leaves and debris first, edges redefined for a crisp separation between turf and mulch, and a granular pre-emergent applied.
Hedge and bush trimming. Pruning and shaping to control size, direct growth and support flowering, from foundation shrubs to ornamental grasses and crape myrtles.
Leaf removal. Weekly leaf removal as an add on to mowing, bagging the cut so leaves come off turf through the fall. Complete leaf removal as a one time clearance of the whole property, including stairwells, decks, patios, fence lines and around the condenser unit. In Herndon we time the complete service around the town’s vacuum leaf schedule for your side of the W&OD Trail, so material is out when the trucks are on your street rather than three weeks after.
Grass that grows thick in one part of the yard and thin in another is usually uneven nutrient availability rather than uneven care. Slow release product evens it out over the season without burning, and each visit leaves written guidance.
We offer three Lawn Fertilization packages:
Premium Care. Eight services with aeration and overseeding included.
Basic Care. Five services, six to eight weeks apart.
Basic Care Plus. Seven services. Lime in summer, grub control in spring.
Premium double shredded hardwood, three colors. Black draws the eye to the planting, brown and natural give the softer finish that suits older in-town properties.
Our Herndon mulch service includes:
A granular pre-emergent to limit weed growth
Beds cleared of weeds, leaves and debris
Hardwood mulch laid at a uniform depth
Edges redefined for a crisp line against the turf
Equipment suited to the site pulls plugs cleanly on smaller in-town lots where there is no room to work roughly. Seed meets National Seed Association standards and a starter feed goes down with it, followed by watering and mowing guidance.
Does the town take my grass clippings?
Yes, on your regular trash day, but the rules are specific. Yard waste has to be in a sturdy reusable container of fifty gallons or less, no more than fifty pounds loaded, marked “Yard Waste,” or in thirty gallon paper yard and leaf bags. Our preference is to leave clippings on the lawn where growth allows, which feeds the soil and keeps your container capacity free.
When is vacuum leaf collection?
October through the second week of December, and the town alternates between the areas north and south of the W&OD Trail, so your dates depend on which side you are on. Check the current schedule each autumn, since the rounds shift with weather and leaf drop.
Can you take away branches from a tree we had cut down?
The town will not collect material cut by tree companies or contractors, and that includes trunks and stumps. Brush from ordinary yard maintenance is collectible if it is bundled to under four feet and fifty pounds with nothing thicker than three inches. Anything beyond that has to be hauled privately, and we will tell you in advance rather than leaving a pile that gets refused.
Do I need permission to remove a tree that is killing my lawn?
Possibly. Within the Town of Herndon a permit is required for removing a healthy tree located in a Resource Protection Area on private property, and applications proposing removal of three or more trees generally need a letter from a certified arborist. The town has its own urban forester who administers this. Check before you plan a lawn renovation that depends on the tree coming out.
My back yard has never grown grass well. Is that fixable?
It depends on how much light it gets. In-town Herndon lots often sit under a canopy that has been there for fifty years or more, and below roughly three hours of usable light, turf will not sustain a stand no matter how it is fed or seeded. Raising the mowing height and overseeding annually with a shade tolerant mix is the right approach where there is enough light. Where there is not, converting to a mulched bed produces a better looking result for less money over time.
