Sandbur Control for Turf

Sandbur is a summer annual grass best known for its sharp spiny seed burs. It invades dry sandy or disturbed turf and creates a serious nuisance for people and pets.

How to Identify Sandbur

Plants resemble a low grassy clump until seedheads form rows of hard spiny burs. Seedlings are easiest to manage before burs develop.

Why It Appears in Turf

Thin drought-stressed turf, sandy soil, low fertility, and bare high-traffic areas favor germination. Burs spread on shoes, equipment, animals, and soil.

Make the Site Less Favorable

• Maintain the recommended mowing height and avoid scalping.
• Correct irrigation, drainage, compaction, fertility, or shade problems that thin desirable turf.
• Repair bare areas and use adapted turf cultivars to close openings where seedlings establish.

What University Research and Extension Guidance Says

University of Georgia guidance notes that timely preemergence programs can reduce summer annual grasses including sandbur, while postemergence options depend on turf species and growth stage. Prevent seed production and rebuild density in infested dry areas.

Choosing a Turf Herbicide

Use the products below as a starting point, then match the herbicide to the desirable turf species and the weed's growth stage. Preemergence products must be applied and activated before germination; postemergence products work best on small, actively growing weeds. Repeat applications may be needed where the label allows.

Research and label note: University research may discuss treatments or timings that are not permitted on every turf species or use site. Research evidence does not expand a product label. Confirm the desirable turf species, use site, target weed, application timing, rate, adjuvant directions, and reseeding restrictions on the current label before use.
