Getting rid of centipede grass
We moved and I planted a new garden in May. Used a rototiller, added amendments, and mulched. Now I have this awful grass coming up between my plants. My neighbor said it was centipede grass. The grass is a shorter variety and some of it is longer. I think the builder had his extra lots covered in this. I was thinking of making a cardboard shield (to protect my plants) and spraying with round-up. I have worked extensively at trying to pull it up, but the root base does not pull out very easy. Any other suggestions?
