This blue-green weed is quite drought-resistant and tolerant of winter weather. The flowering stems have seedheads that contain many stiff, yellowish-green branches. If left alone, this perennial plant will stay green all year round.
Known for growing in clumps around the northeastern US, orchardgrass can unexpectedly creep up on your lawn. Most infestations occur from grass seed that has been contaminated with orchardgrass. Luckily, just a few simple steps will keep this coarse weed out of your yard.
Orchardgrass grows best in the cool weather of spring and fall. When temperatures climb into the 80s, growth decreases greatly. It can adapt to grow in shady areas as well as survive frequent mowing. If you aren't careful, this highly competitive grass can overtake the grass you want in your yard.
Orchardgrass can be controlled in a couple of ways. If the infestation is small, you can remove individual plants by cutting them out with a shovel. Dig out 3 to 4 inches deep to make sure you get all the roots. Replant the area with soil and seed that matches what you have in your yard.
If the infestation is widespread, apply a Roundup® Brand Weed & Grass Killer to the unwanted weeds only. You can reseed the treated areas after about 5 to 7 days, as long as you don't use Roundup® Weed & Grass Killer Extended Control, which will keep turf-grass seeds from growing. Be careful not to spray your turf grass, as these products will damage your lawn.
