St Augustine - divit holes, matted mounds and dead areas
We have St Augustine grass that has a few problems to fix.
The grass went all yellow in the winter months -- which here is just a little colder, it's not cold. There are trianglular spots where the grass didn't come back, and I think I've figured out that the water misses it entirely in those places. Ooops. When we bought this house 1.5 years ago the sprinklers were set to go off every day. It is HOT here in the summer but that seems crazy.
2nd problem: uneven/unsure footing. There are big long divits. Actually more like potholes, hidden by the grass. Some are pretty deep, and I think the dog who left here before us dug them. Can we just fill them in with dirt? In other places I can feel the matted old grass beneath the new grass. It's thick like matted hair and I'm afraid I will turn my ankle on it.
I've read a couple of the St A posts. It sounds like mowing at the highest setting, watering only once per 1 or 2 weeks and feeding it once per year with corn or soybean meal is the right thing to do for maintenance, but what do I do about the unevenness? Should I dig up the dead spots? The matted parts? Just throw dirt in the big holes?
