My moss rose is beautiful, and maintenance free and I'd love to keep it for next season, but I have a black thumb and no greenhouse. Any idea how to do this? This was the easiest plant I've ever had. Found a little stubby one growing out of the cracks of the sidewalk in the city, and put it in a shotglass with some water. Once it had roots, I put it in the dirt, and it's huge now. Doesn't matter if it gets water or not, she's happy.
