So I tried to post this about 20 minutes ago and it didn't work. I got a big problem with my lawn. It is covered in what I think is called Black Medick, it is a clover looking weed with a yellow flower that turns into a little bur. It is okay for the torts but could be a big problem for my dog ( a little poodle). The torts have a pen, but I like to give them the run of the yard when I am home. Is there an herbacide I could use? I think I have too much to pull up. How long would I have to keep the torts off the lawn if I went this route? HELP!!!!!!!!! I need advice!
