This is the first time i have mounted a masdevallia. I took the floribunda var. tuerkemii and attached it to a cork mount. I also put some live moss around the roots in hopes that this would keep it moist enough. Only time will tell. I hope i did a good job of it. Any instructions on helping it adjust to the new mount?
I have a couple M floribunda and I was worrying about root rot too. They are in plastic pots now with some of that moss, but I worry that they are staying too wet. Living in south Florida is going to be difficult for them. Do you think mounting them could help?
