I tried to replace my curb side lawn with some water tolerant plants but another kind of weed just appeared before and spread faster than my intended plant takes roots. I also have this weed on my St. Augustine grass lawn . I don't know what the watrr tolerant plant called and so is the weed. Is there a weed control spray that I can use without killing the plant and St. Ausgutines? And how do I upload more than two pictures?
