I am sorry for this delayed reply to your gardening question. The spring rush has brought a deluge of questions and we are working hard to catch up!
You probably don't need to fertilize but if you want a light application won't hurt. I suspect as you start mowing regularly at a high setting it will get better and better looking in a short time. Water deeply and infrequently for best results.
Thanks for the question. Best wishes for a wonderful gardening season. Please stop in again soon!
