Well you don't want to see my lawn right now, it's a mess. It's been raining almost every day now for the past few weeks and it's really suffered because of it. Even more so when we or the dogs walk over it. Bare patches here and there and a mud trail where we all walk. Nonetheless, my windmill palm that I've had for second year in full ground now is doing well so far and all I did to that planting hole was mix in a lot of gravel, sand and compost and also backfill with it. on top of that and around is just the original clay. I think I might try it with less valuable plants first such as grasses or my calla lilies which like wetness.
