I just bought this Phal today. Personally I've not had great luck with Phals when I buy them potted in moss and of course this one is. There is green mold growing on the side of it's plastic pot. I'm afraid it will rot the roots if I leave it but I don't want to shock it while it's flowering. I have everything to re-pot it but just want to do it at the right time. Any suggestions please? Thank you!
