Oh no! Mine were problematic as well, and eventually totally rotted away. :-(
Aaron is pretty aggressive about pulling off the mold manually, from what he was telling me. Maybe he can give more detail. I hope you have better luck! On the up side, the original tree is regrowing nicely, so Pink Do lives, despite me and LA Dept. Water and Power.
I'm wondering if we aren't barking up the wrong tree by trying to sterilize everything and allowing the mold to grow opportunistically. It was too late for my cuttings, but I wanted to test the theory that they might do better in an environment with other pathogens and materials around to keep the mold in check. I saw an interesting presentation on mushrooms by a mycologist who said that almost all plant species rely on a symbiotic relationship with fungi for their root systems to work, and that disturbing the mycorrhiza is the main reason transplantation can be problematic. I'm not a botanist, though.
Cheers
