Bindweed is a deep-rooted viny weed that is one of the toughest weeds to control in a lawn. Mature bindweed has deep roots that are nearly impossible to physically remove and can survive an herbicide treatment, which is why it needs consistent yearly applications.. As soon as you spot bindweed, begin to get rid of it so you can effectively manage it before it completely takes over your lawn.
Remove small bindweed seedlings by hand whenever you see them, before they grow deep roots.
Choose an herbicide to get rid of bindweed. For example, 2,4-D Amine works well in both the spring just before it blooms and in the fall before it goes dormant. Metsulfuron works well when bindweed is in full bloom. Read the label to be sure the herbicide you choose is safe for your specific lawn grass.
Dilute the herbicide, if necessary. Some herbicides are packaged in ready-to-use bottles. Read the label and add the herbicide and water to an herbicide applicator (such as a backpack sprayer). Usually only 1 to 2 ounces of herbicide is needed for every gallon of water, which is typically enough to spray 1,000 square feet of lawn.
Spray the herbicide according to manufacturer directions on a calm, dry day. Wear long-sleeve clothing and goggles to protect yourself. Keep pets and children indoors and spray the herbicide evenly across the lawn.
Repeat every year to effectively get rid of and control bindweed. If the bindweed continues to grow after two or three weeks, repeat the treatment or try a different herbicide.
