Bahiagrass Control in Turf

Bahiagrass is a tough warm-season perennial bunchgrass that can be desirable on roadsides and low-maintenance sites but objectionable in fine turf.

How to Identify Bahiagrass

Coarse leaves form open clumps, and the tall seedhead usually has two branches that form a distinctive Y shape.

Why It Appears in Turf

Low fertility, drought, open turf, and seed movement favor establishment. Deep roots and persistent crowns make mowing alone ineffective.

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

UF/IFAS guidance emphasizes that control depends heavily on the desirable turfgrass. Some selective options are limited to particular warm-season species, and repeat applications or spot renovation may be required.

Choosing a Turf Herbicide

Perennial weeds often regrow from stolons, rhizomes, tubers, bulbs, or deep roots. Select a product labeled for the desirable turf and target weed, treat actively growing plants, and plan the complete sequence of repeat applications or renovation steps allowed by the label.

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.
