|we reseeded out lawn last sept and it looked great. Now there is orchard grass in it. what can we do?|
|When there are few weedy patches, orchardgrass can best be cut out with a shovel. Be sure to cut down three to four inches into the soil to get all the stems. The holes should be refilled and seeded or sodded immediately. The seed and soil should be representative of that already in the area. If the area has a large number of plants, chemical control will be more efficient. A nonselective systemic herbicide such as glyphosate (Roundup, many others) or glufosinate (Finale) can be spot-applied. These herbicides will also kill the turf; use care during application. The area should be reseeded 5 to 7 days following application. Stir up the soil by raking or chopping to insure good seed-soil contact.
Often the orchardgrass will grow taller than the surrounding turfgrass. This gives the opportunity to use a wick applicator filled with glyphosate. You pass the wick over the top of the orchardgrass without touching the turfgrass below.
Hope these tips help!
