hi all .I started rooting mint cutting a week ago in water .I put a sprig of fresh mint in a cup of water and covered it with a transparent nylon bag to retain humidity and prevent direct sunlight as it is hot here in Egypt (up to 86 F )this days.when I checked the plant today i saw roots from almost all the nodes of the plant(submerged and not submerged parts ). What shall I do ?shall I remove leaves from all rooted nodes and bury it all or just bury the lower one or two nodes ?
another question : Is planting in peat moss only better or in sterilized garden soil as I don't have a lot of options regarding soil?

Thanks in advance
