How do we get rid of the burweed stickers in our HOA's common-area lawns?

By OurHOA · General information · Revised October 31, 2026

How an HOA board stops lawn burweed stickers in common turf: fall preemergence timing, winter sprays before the spines harden, grass-safe products and licensed crews.

Part of the HOA board handbook: vendors, projects and upkeep.

When to act and what works

Lawn burweed, also called spurweed or sticker weed, is a winter annual. It sprouts in the fall, hides in dormant turf all winter and makes its spiny burs in spring. By the time owners complain about stickers in their kids' feet, the plant has done its damage, and a spray won't remove the burs. Mississippi State University Extension says that once the burs form, control options are futile. So burweed control runs on the calendar, not on complaints. Put down a preemergence herbicide in early to mid fall, before the seed germinates. Spot-spray the plants that get through between December and February, while they are small and have no spines. Thicken the turf so next year's seed finds less bare ground. Then do it again the next year. University of Georgia (UGA) Extension says treating consistently for at least two years in a row can nearly eliminate burweed in most lawns. Licensing rules for herbicide work vary by state, and your governing documents may split lawn care between the association and owners in their own way. This guide is general education, not legal advice.

Make sure it is burweed

Mississippi State describes small rosettes of finely divided leaves that look like tiny parsley or carrot tops, flat against the ground in thin or dormant turf. Small white flowers appear in early spring, and clusters of burs form where the leaves meet the stem. Each bur holds a seed and hardens into a spine as it matures, and the burs stay in the turf after the plant dies. Texas A&M AgriLife Extension in Austin County, which also calls it stinging grass, says the leaves are opposite and sparsely hairy and that the plants start dying back in late spring, when air temperatures reach 90 F. Sandbur is a different weed. It is a grass, it grows in sandy, thin turf, and its season is different, so the plan for it is different too. Our guide on controlling sandburs in HOA common turf covers it. If the stickers show up in March and April on low, ferny plants in a lawn that was brown all winter, you are looking at burweed.

The two treatment windows

Fall preemergence. Mississippi State calls preventing emergence the most effective strategy. It says to apply in October or November there, before soil temperatures drop below 70 F. The Austin County agent gives late September to early October for Texas, before winter weeds germinate, and UGA's agent in Southeast Georgia starts as early as late September because germination can begin early. Granular products need about half an inch of rain or irrigation to activate, per Texas A&M, and Mississippi State says watering in right after application helps. In practice that means approving the bid in August or September. A board that misses the fall window should not write off the year. Budget for the winter window instead. Winter postemergence. Mississippi State and Texas A&M both put the window at December through February, when the plants are small and have no burs yet. UGA says burs begin forming in March and harden by April, and that a mid- to late-March spray before they harden can still cut the problem down. Texas A&M warns that spring treatment often takes repeat applications, which raises the risk of injuring the turf. Mississippi State says complete control may take multiple applications spaced about four weeks apart. UGA also says to avoid postemergence sprays during spring green-up or hot weather.

Match the product to your grass

The grass type decides the product. Give the contractor a map that shows what grass is in each area, and make the bid name the active ingredient for each one. - Isoxaben is a preemergence option labeled for bermudagrass and St. Augustinegrass, per Texas A&M. Don't reseed or overseed within 60 days of applying it, and don't apply it to a newly seeded lawn until it has been mowed three times. - Mississippi State lists atrazine, simazine, prodiamine, dithiopyr, indaziflam, pendimethalin and isoxaben as effective preemergence ingredients, and its product table warns that several may interfere with sod, sprigs or plugs. Leave out any area you plan to resod next spring. - UGA says atrazine works on centipedegrass and St. Augustinegrass, with limited postemergence activity, and that simazine gives strong residual control of winter annuals in warm-season grass. - For winter spot sprays, Texas A&M names three-way broadleaf products containing 2,4-D, dicamba and mecoprop (MCPP) for bermudagrass and St. Augustinegrass. UGA calls metsulfuron highly effective in bermudagrass and zoysiagrass but says to use caution on centipedegrass and St. Augustinegrass. Skip weed-and-feed in late winter. UGA advises against high-nitrogen weed-and-feed products then, because warm-season grass is dormant and early nitrogen leads to uneven green-up and weak spring growth. Save fertilizer for late spring. For every product, the label sets the rate, the grasses it is safe on and the reentry rules, and the crew should follow it exactly.

Treat first where people walk barefoot

Most associations can't afford to treat every acre, and they don't need to. Rank the common turf by who uses it. The playground lawn, the grass around the pool, the dog area, the clubhouse lawn and the strips beside walking paths come first. Pond banks and back greenbelts that nobody crosses barefoot can wait or get a single winter pass. The lasting fix is thicker grass. Mississippi State calls a dense, healthy turf canopy the most reliable cultural defense and says burweed pressure is highest in thin, stressed turf, often on compacted soil. Its list fits neatly into a landscape contract: - the right grass species for the site - fertilizer and pH based on soil tests - the correct mowing height for the grass - deep, infrequent watering during drought - aeration where the soil is compacted - washing mowers and other equipment after use so the crew doesn't carry seed to the next area The Austin County agent makes the same point. A healthy, dense lawn competes with burweed for light, water and nutrients. Our guide on hiring an HOA landscaping contractor covers how to write those duties into the scope.

Who may apply the herbicide

Herbicide on common turf is pesticide work, and the licensing rules are tighter than many boards expect. - Texas. Tex. Occ. Code 1951.003(a)(1)(B) counts treating pests of trees, shrubs or other plantings in a park or adjacent to a residence, for pay, as structural pest control, and 1951.301(b) bars anyone from that business without a license. Ask the contractor for the Texas Department of Agriculture license number and the category it covers. - Florida. The limited certification for landscape maintenance workers in Fla. Stat. 482.156 covers herbicides in plant beds, driveways, sidewalks and patios, with handheld or backpack equipment only. Subsection (4)(a) says it does not authorize applying pesticides to turf. A mowing crew that holds only that certification should not be spraying your lawns, so ask which chapter 482 license covers the turf work. - Other states license this work too. Wherever you are, ask the state agriculture department or your county Extension office which license fits before you sign. Put the license number and a certificate of insurance in the bid file before the first application.

Calendar, motion and owner notice

A sample year. August: walk the amenity lawns, pull last spring's complaints and mark where burweed showed up. September: approve the preemergence bid. Late September to mid-October: preemergence on the priority areas, watered in. December to February: scout the treated areas and spot-spray survivors, with a follow-up about four weeks later if needed. March: last chance before the burs harden. April and May: note where stickers still appeared so next fall's map is better. Summer: aerate, fertilize from the soil test and keep the mowing height right so the grass closes in. Motion: "Move that the association approve [contractor]'s bid for fall preemergence and winter postemergence lawn burweed treatment on the playground, pool and path turf shown on Exhibit A, at a cost not to exceed $[amount] for the season, and that the contractor provide its license number and certificate of insurance before the first application." Owner notice: "The association will treat the playground, pool and path lawns for burweed, the weed behind the spring stickers, on or about [date]. Please keep children and pets off treated areas for as long as the product label directs. If burweed grows in your own lawn, now is the time to treat it, before the plants form burs." The mistakes that keep stickers coming back: waiting for spring complaints, spraying in April after the burs have hardened, using a product the grass can't tolerate, putting a preemergence down where sod goes in next spring, overseeding inside isoxaben's 60-day window, applying weed-and-feed to dormant grass, hiring a crew without the right license, and stopping after one good year.
