I picked a small plant of this species up last weekend. It was potted in peaty crappy soil, and I put it in the windowsill until I could repot it later int eh week. When I looked at it 5 days later it was already very dehydrated and the mature leaves were brown...argh!
I've never seen a succulent need so much water! What do people use for soil mix for this species? I'll be potting it in plastic for sure! It will summer outdoors here in coastal zone 5b.
