How can I get rid of the oniongrass in my yard when regular weed killers don't work?
I can't seem to find a solution to the multitude of oniongrass growing in our lawn. The regular weed killers don't affect it. Do you have any ideas?

Wild oniongrass is hard to kill with chemicals, but it can be done. Use a combination broadleaf herbicide product, such as Trimec, that contains two or three chemicals; ask for the ester formulation. You’ll need to make the application in early spring, when the oniongrass is actively growing. One precaution: Ester formulations are a little more potent than other formulations of the same product. You should apply ester formulations only during cool weather (spring and fall) and never use them close to ornamentals.
