If I remember right the instruction that came with the Corkscrew Ell Grass said to plant it just to the crown or something like that. When I started planting I was barely able to keep my head above water at times,(the water was cold and I was in a wet suit) and so I was just stuffing the plants into the mud and I thought this isn't going to be good. But they don't seem to care. I planted in some sand where I once had a beach and in muck/mud and they grow well in both. In sand they aren't rooted as well and I have knocked some loose launching and beaching my boat. Once I had the plants planted I walked around the pond and some had floated up to the surface so I replanted them.
I would like to say also, that the area I had the 55 flags marking the individual plants that when you just walked by and looked at them you would think you were looking at 8 or 10 plants. But when you really got down close all the plants came into view. Many new plants were just up an inch or so.
