If the pumice seems to dry out too fast try mixing in some lava and akadama in 3 equal parts followed by top dressing. I have several trees in pure pumice that I purchased that way and they don't seem very tough. I'm going to repot late this coming winter into a mix I referenced above and we'll see if there's a difference for me
I've got some crushed lava, but can't seem to find more of it anywhere.
What I'm wondering about the moss is, how will I know when to water if I've got a layer of that covering my soil?
