I am trying to find a cheap way to fill my large pots with a growing medium for tall sundews---Binata, Filiformis, etc. I heard you can use woodchips, but wouldn't that decompose and leave minerals and stuff behind? I know moss can grow from trees but am wondering about that.
Also, are all varieties of woodchips the same? i.e. cedar vs. cypress, etc.
Thanks for the help,
