About your house foundation, keeping it wet enough for vegetables or plants can be a problem, not to mention sinking wood near it that could attract termites. I've switched to big pots on big saucers near the foundation.
It sounds like you want to make a vertical post hole and fill it with a log? That will sink and settle much more than a horizontal log that stays consistently wet a foot or more below the surface. A long, skinny hole in the ground that has 50% of the wood near the surface will not be as wet for its full length, nor be as amenable to soil critters who want to live in and around it.
Driveways are expensive to maintain if they start cracking, and drilling under or around them just might cause something like that

I just want something to grow there besides weeds. I figure any "good" growth would help clean it up. I was looking at it just now and it's quite swollen upward so bricks or pavers aren't going to work.
