Once again, failure to plan is biting me square in the rear-end. I have a few spots along the outfield wall that just won't grow very well. It's hit and miss, and mostly miss. At first I thought it must be just poor drainage. Nah. Too little water? Nope. Act of God? Not nearly. The answer is so simple that it completely passed me by.
You see, everywhere else in the yard, the grass grows like crazy. Despite the rocky soil, the roots are doing very well and growing deep and strong. Therein lies the problem. All along the wall and in certain spot in particular, the soil is very shallow, for a very good reason. Whomever built the wall wanted it to stay and really got crazy with the footing. It's shallow, wide and thick. Great for structural stability, bad for grass. Especially hybrid bermuda, which likes to throw down some deep roots.
The way I found out this was the cause was while I was coring the yard a few weeks back. I couldn't get more than an inch into the ground along the wall. Ooops. That was a sinking feeling.
So, I went to the store and got some turf soil to throw down in hopes that by adding a better, deeper base for the roots the grass will return. It might be all for naught though. If so, I'm going to dig up the grass along the wall, to about 18" out from it and make a warning track. It will look nice, but it will be purely aesthetic. An 18" warning track gives you about a tenth of a second warning before you break yourself against the wall. Oh well, it'll give me a chance to test out my homeowners insurance I guess.
