When my sod was about a month old, we (accidentally) didn't water it for about it a month, causing it to go dormant. Over several months, most of the grass came back, but now it has several large bald spots similar to this picture.
I've tried removing some of the dead grass in those dead spots with a rake like this, but with all the green netting under the old sod, it makes it nearly impossible.
What's the best way I can remove this dead grass having the sod netting underneath so I can put down a lot of fescue and fix these bald spots?
