Now that turf grass is “waking” from winter dormancy, it’s time to look after the lawn. Here’s a helpful article from Ward Upham at K-State on Orchard grass.

“Orchard Grass in Tall Fescue Lawns
Orchard grass often infests tall fescue lawns. Unfortunately, orchard grass is lighter green and faster growing than tall fescue, so it is very visible. Homeowners complain of the light green tufts of grass wherever this weed has become established. Even worse, there are no herbicides that will kill the orchard grass without also killing the turf. About the only good thing about orchard grass is that it is a bunch grass and does not spread.
Orchard grass often comes in as a contaminant on grass seed, especially K-31 tall fescue. Buying good grass seed is the first line of defense against this weed. Orchard grass is a pasture grass and therefore is not found in the “weed seed” portion of the seed label. Rather, orchard grass will be listed as “other crop seed.” Try to buy grass seed that has 0.0% “other crop seed.”
Control options are few and painful. Use glyphosate (Roundup, Killzall Weed and Grass Killer, Kleeraway Systemic Weed and Grass Killer and others) to spot spray orchard grass clumps. Any lawn grasses you hit will be killed, so keep the spots sprayed as small as possible. Wait until the spots have turned brown and then cut out the clumps and replace with a small piece of sod. Large numbers of orchard grass clumps may mean it is more practical to kill the entire lawn and start over.”
