Grassy Weed – Creeping Bentgrass

(Agrostis palustris)

Creeping Bentgrass – also referred to as Wire-grass Drop-seed – is a perennial grass that is considered to be a weed when present among other grass species. Agrostis palustris is commonly used on golf courses and other athletic fields. Creeping Bentgrass thrives throughout much of North America.       

Identifying Creeping Bentgrass -

Creeping Bentgrass can be identified as a low-growing, fine-bladed perennial. It has a creeping growth habit which is spreads by long, vigorous stolons. Its ligule is tall and rounded, its collar is narrow and its sheaths are smooth, not compressed.  This perennial grass also features narrow blades that are flat, veined, and rough along the edges.

Creeping Bentgrass Control -

Creeping Bentgrass is most commonly used for putting greens on golf courses and has the ability to creep into areas where it is not a desired turf type. Creeping Bentgrass is also a common contaminate in cool season turfgrass seed. This grass can spread aggressively and cannot be easily controlled using cultural methods. Always purchase premium, professional-grade grass seeds from trusted lawn service providers to avoid contamination.

Creeping Bentgrass

Scotts LawnService recommends cultural practices to fight Creeping Bentgrass. This is due to the limited number of selective weed control products options to kill this weed. However, this weed can be controlled with non-selective weed controls such as Round-Up®, which will kill this weed and surrounding turfgrass.  Re-seeding may be necessary to repair treated areas where Round-Up is used.
