I have dry spots in the lawn. More watering would overwater the rest of the lawn. Spot watering does not work well with my work schedule. The dry spots are about 3 feet from sprinker heads, so it may be that much of the spray goes over them, but that doesn't seem to be a problem with other sprinker heads. I don't see how I can manipulate the sprinkers to improve the spray.

I have a way of dealing with the dry spots, but I am an amature, and I'm not sure my method is the best -- or is even working, for that matter.. What I have done in the past is pour some spongy soil on top of the dry spots in the expectation that it will retain the moisture. I have used Kellogs Topper to pour directly on top of the dry spots. It seems to work, but I'm not sure. I have seen improvement in some spots, but not the worst ones. That may be because I didn't put enough on.

Is this a good plan?

Is there a better plan?

Background:
I confirmed that it is dry spots by pushing a screwdriver into it. Screwdriver only goes in about 1.5" in the dry spots, but I can push it in to most of my lawn fairly easily to about 6"
