Matted artificial turf: brushing it back up after snow, dogs and traffic

01Why does artificial turf go flat?

Weight on the blades, and too little infill between them to push back.

• Snow. Fort Collins’ nearest NOAA station averages 51.4 inches of snow a year, Loveland 2N 47.0 and Greeley UNC 34.9 (1991–2020 normals; Fort Collins, Loveland, Greeley). Synthetic Grass Warehouse, a turf distributor, says snow, ice and debris from heavy wind can mat blades over weeks or months (SGW).
• The same path every day. Back door to gate, or the dog’s lap along the fence. The Synthetic Turf Council says high-wear areas show the most pile flattening and need extra attention (STC).
• Low infill. Motz, an infill maker, calls low infill depth the main reason fibers flatten and won’t stand. It blames installers who put down too little, and infill that settles or gets kicked around over time, “especially in highly trafficked areas,” by kids and pets (Motz). Motz sells infill, but the STC makes the same link: brushing keeps infill even and fibers upright, and flattened fibers can speed up wear.

Matted turf also looks shiny and artificial, Motz says; SGW’s power broom column explains that fibers leaning one way reflect light (SGW). More on the look is in what makes turf look real.

02How do I brush matted turf back up?

Pick a dry day: the STC says brushing is most effective on a dry surface. After snow, wait for a thaw too, since frozen blades go brittle, SGW warns (SGW).

1. Clear debris first, so the broom isn’t grinding grit into the fibers. Leaves, cottonwood fluff and needles are covered in getting leaves off turf.
2. Brush against the lean. Look at which way the blades lie and push the other way. SGW calls this cross-brushing: use a broom with synthetic bristles, and avoid metal prongs.
3. Then brush in several directions. Motz says against the grain first, then all directions, so the blades look natural and the infill spreads evenly. The STC also alternates direction from one brushing to the next.
4. Press-test it. Push the blades down lightly. Motz says they should bounce straight back; a spot that stays flat probably needs more infill.
5. Top up the thin spots, then brush the new infill in. How much and how often is in how often to add infill; for a dog run, see dog turf infill.

Time the spring brush-out. March is the snowiest month on average at Fort Collins, with 9.4 inches, yet snow an inch deep covers the ground only about 3.9 days that month. April still averages 6.2 inches there, 5.7 at Loveland 2N and 3.7 at Greeley UNC; May averages 1.6, 1.1 and 0.5 (NOAA monthly normals, 1991–2020: Fort Collins, Loveland 2N, Greeley UNC). Storms keep coming into April, so one whole-yard brushing in late April or May, after the last big one, saves doing it twice. That is our reading of the normals, for Fort Collins, Loveland and Greeley alike.

SGW’s spring checklist adds loose seams, lifted edges, broken blades and sagging spots, which brushing won’t fix: see turf edges lifting.

03Do I need a power broom or a turf sweeper?

Probably not to own. The tools do different jobs:

A power broom is a motorized, string-trimmer-style tool with a spinning brush head. Needed once or twice a year, it’s a rental or a hired job. If you run one yourself:

• Nylon bristles. Motz specifies a power broom with nylon bristles, and FieldTurf allows rotary brushes with “nylon bristles only” (FieldTurf).
• Not too low. The STC warns that a brush set low enough to dig into the pile or backing can damage the turf and seams and disturb the infill.
• Easy on the passes. SGW says some models can be flipped over for a gentler final pass, and that excessive power brooming can cause memory loss and premature matting, and splits slit-film fibers into thinner strands.
• Never set it down on the turf. SGW says a power broom’s engine gets hot enough to melt the fibers, and says to refuel off the turf. Brushing in July? Read how hot turf gets first.

04How often should artificial turf be brushed?

As often as traffic flattens it, and no more. Published figures:

SYNLawn sells that service, so treat its figure as a ceiling for a quiet lawn. For most yards here that means the spring brush-out, spot brushing of paths and dog areas as they flatten, and a machine pass only when the whole yard needs one. The full year of upkeep is in does artificial turf need maintenance.

05Can I use a leaf blower or vacuum without pulling up the infill?

A blower, yes, held back and angled. A vacuum, generally not.

• Leaf blower. FieldTurf says no closer than 2 feet and at a 45-degree angle. Motz says about 12 to 18 inches above yard turf (Motz). The STC adds: don’t point the nozzle straight into the turf, and keep the throttle low.
• Vacuum. FieldTurf’s repair instructions use a shop vac on purpose to pull infill out of the turf backing so it can be reused. On infilled turf, a vacuum takes infill with the dirt (our reading). The deep-cleaning machines the STC describes combine brushing and suction with an infill return system; a shop vac has no way to put it back.

06When is flat turf worn out rather than matted?

When brushing and fresh infill no longer bring it back. Signs:

• Blades stay down after brushing and topping up. Motz says turf left on low, uneven infill can decline to a point where there’s no getting 100% of its former quality back.
• Fibers snap at the infill line. SGW’s column says constant foot traffic makes fibers lose their memory, and lifting them every month creates a break line at the infill level where they can break off (SGW).
• Blades split into thin strands, the over-brooming damage SGW describes on slit-film fibers.
• Creases. The STC lists fibers that are “significantly bent, creased and flat” among the conditions that call for deeper work.

A worn path isn’t a brushing problem. SYNLawn recommends stepping stones or pavers on high-traffic paths (SYNLawn DIY guidelines), and SGW’s column suggests concrete, pavers or stepping stones instead of turf at entrances and exits. For a new yard, the same column says high-traffic areas may need a textured or grooved fiber; ask for it on the turf spec sheet.

07What should I ask a turf-care service before it brushes my yard?

• What bristles, and how low does the brush run? A good answer: synthetic or nylon bristles, set to lift the blades without reaching the backing.
• Will you check the infill depth and top it up? A good answer measures before and after. Brushing alone won’t hold blades up on thin infill.
• Gas or battery? Not legal advice. Since 2025, Colorado’s Regulation 29 has barred municipalities, public school districts and special districts in the state’s ozone nonattainment area, and their lawn contractors, from using small gas-powered push and handheld lawn equipment from June 1 to August 31. CDPHE says that area takes in the northern Front Range, including northern Weld County (nonattainment areas); its Air Pollution Control Division can say whether an address is inside. In November 2026 the Air Quality Control Commission will consider extending the rule to commercial lawn equipment (CDPHE). It covers any tool meant for lawn cleanup or maintenance; that this takes in a power broom is our reading, not the state’s. If a district or HOA contractor brushes your turf in summer, ask which machine it runs.
