Organic Control of Sandburs (Stickers) in the Lawn: Cultural Practices That Work

Sandburs—those painful, spiny "stickers" in your Texas lawn—are an annual grassy weed (Cenchrus spp.). They thrive in thin, poorly managed turf. Chemicals like MSMA, pendimethalin, or oryzalin are hazardous (carcinogenic, ecotoxic) and unnecessary.

Organic Cultural Control

• Mow high (3–4 inches). Tall grass shades out sandbur seedlings. One study eliminated crabgrass entirely in tall fescue just by mowing at 4 inches.
• Water deeply and infrequently. Sandburs are shallow-rooted; a dry surface layer between waterings gives deep-rooted grass the advantage.
• Hand-pull before seed set. A Texas A&M researcher took three years to clear his yard this way—but it worked.
• Build a dense, healthy turf. Overseed with adapted grasses, topdress with compost, and follow soil test recommendations.

Encourage Natural Enemies

Ground beetles eat sandbur seeds. Birds eat the plants. Don't use broad-spectrum insecticides—you'll kill your allies.

Sandburs are a fact of life in Texas. A thick, tall, well-watered lawn is your best defense—no chemicals required.
