It's in a mound of excess dirt that piles up and is pretty rich for growing things. There are also some pepper plants growing in the middle of them which I wasn't sure would grow since they were just tossed out there for giggles. Now there are so many sprouts that they will need to be thinned out quite a bit. I might end up transplanting them into pots for the fall plant swap. Already producing pepper plants should go over ok.
