Obnoxious Onion Weed...HELP!
I've finally identified that I have onion weed. I get more and more every year. I continue to dig it out right down to the bulb(s) but it continues to get worse. I've used Roundup on it but it doesn't seem to do anything. It is confined to my flower beds and not in the lawn. I don't mind having to lose some plants in the process of killing it but the onion weed has got to go!
SpeedZone covers wild onion as well as hundreds of other broadleaf weeds infesting your lawn. Refer to the product label for instructions on dilutions for your lawn type
