In my experience that once milkweed is established, it will spread by underground runners and be hard to control. As for Creeping Charlie, these web pages contain information on herbicides that may be used. In my garden, taller plants like iris, monarda, etc. will grow up in spite of the CC. Getting rid of it without damaging desired plants is difficult. The wet weather we have been having does not help. Good luck.
