Hi, over a year ago we planted Kings Pride Buffalo grass. It seemed very soft and bouncy when we first planted it. Now, however it has many seeds which are spiky. It actually hurts to walk on it or lie down on it. We have tried moving it lower. This helps partially but It's still spiky. We water it every 2 days for 15mins (Summer) and once a month we weed and feed it. How can we reduce or remove the seed spikes? Why is it doing this?
