you can use weed be gon. There is a special clover one but i find that the regular one works very well.

What kind of grass do you have?

Yes, need to know what grass. WBG is not good for a couple of them.

Weed b Gon Chickweed, Clover, and Oxalis Killer is the special one. Some people don't have clover, but they have one of many weeds that looks like it.

Trimec worked awesome on our clover, it died out after one application.
