Orchardgrass is usually seen as a rapid-growing weed when it sprouts on a lawn. It is a perennial grass that can grow tall, and it also can grow in almost any soil condition. An easy home remedy can rid your yard of orchardgrass in just a few days.
Study your lawn to determine where orchardgrass is growing. Try to determine its spreading pattern so you an anticipate where it is going to sprout up next. It resembles a tall, thick grass with a wheat-like bushy top.
Fill a spray bottle with the white vinegar and do not add anything else. You will need about 2 cups of vinegar for every square foot of the weed.
Spray the orchardgrass at a close range with the vinegar, making sure to completely saturate the area where it is growing.
Watch the orchardgrass, as it should start to dry up after 30 minutes and be completely dead within two days. Remove any dead orchardgrass with your hands and discard. If it is not all gone, repeat the process.
