Oh Deebie, thanks for the tip about chicken grit, I need to repot my Adenium. I bought some pumice, and I like it a lot because it helps keep the pot heavy enough so they don't tip over, seems to work like perlite, but no "floaters" problem which drove me crazy (no Rhino Beetles here in Seattle!) But pumice is $$$. However I have a bag of granite chicken grit in the garage I can use, I think it is #2. Super cheap. Which size do you use?
