I ordered some Sempervivum and Jovibarba this spring. Some have babies others wont even open. I am still tring to propigate plants from leaf cuttings. So far no luck. Do you have any suggestions? I have a bag of perlite and have been using it to put the cuttings in. So far every attempt has either just dried up and died or burned. I live in the desert zone 9 so its challenging, but I am not giving up.
