Can anyone tell me how to get rid of pig weed and another purple stem weed that grows very large. They have taken over my garden and no matter how much you pull they just keep coming back. That have over taken my strawberry and I will need to get them clean come spring time. Please help. What is the most cost effect way to get really good workable soil? I hope someone can help me.
