Triv grass

Weed grasses are among the most difficult weeds to treat and control in lawns.

The leaves appear shiny, light-green and may take on a bronze hue during heat or drought stress. Patches of this grass often resemble areas where petroleum products may have been initially spilled. It spreads rapidly using lateral creeping stems called stolons which can smother desirable turfgrasses. Like creeping bentgrass, this growth habit is incompatible when mixed with upright turfgrass species like perennial ryegrass or turf-type tall fescue. In home-lawns it forms puffy patches of turf that are prone to mower scalping. Additionally, it is prone to infection by numerous turfgrass diseases like dollar spot and brown patch. This grass has become a serious problem weed over the last 15 years especially in Kentucky bluegrass and turf-type tall fescue.

Once lawn grasses are actively growing, the annual bluegrass will appear to be a lighter yellow-green in comparison to the turf. Improving turf density through fertilization, removing trees or trimming branches to reduce shading, reducing irrigation, and use of turfgrasses well-adapted to site conditions will help slow the spread of P.
