Hi, I am a new Homeowner and have not had a lot of experience with different types of weedkillers and fertilizers and such. In the front and on the sides of my home I have a Vine type Groundcover that is pretty common around here in Mississippi. I have seen it in many places looking very plush green and nice. Mine currently has a lot of areas that are looking unhealthy. Below is a closeup pic of the type of groundcover I'm referring to. Last year I used a fertilizer on it i believe was a 13-13-13. It greened up pretty nice but it also went crazy with weeds. My main question is this. What can i put on this to destroy all of the weeds that come up yet not hurt the vines/groundcover? I want to green it up and make it nice and plush. I don't have any flowers or anything in it that would be hurt. Just some shrubs and some decorative grass patches ive always referred to as monkey grass... no idea if that is what it is really called. Pic below.
