If you are like me and spray the weeds yourself rather than call a company to do it and aren't sure what to do, let me share what I did and whether it worked or not.
There are a lot of varieties of weeds in Idaho. A lot. Some of them we like and give them pretty names like dandelions or wildflowers (but they are still a weed if they are in your yard). Others are so terrible that no cute name can make them desirable - those weeds are Goat Head and Bur Buttercup.
