Hi Tracy. Welcome to the site, others might contradict me with this advice. Scarify now if you must but remember it will look worse before it looks better. I would just leave it be, cut it on a high setting when it needs it ,water it when it needs it and leave the rest until autumn.
If you can post a picture people can see exactly what problems you have and offer advice easier. To post a picture use the green tree icon on the right of the tool bar.
