Uh, . . . smoking pot, no . . . getting potted, no . . . I got it !!! RE-potting !!! Am I right, Huh Huh !?!?
Just did a bit of that myself here, cleaning up and repotting a horribly mistreated Den NOID given away to another member that I picked it up for !! Flopping around, literally, in an 8" pot full of sphagnum !!! Put it in a 5" pot withOUT sphagnum, used bark/leca combo, and rhizome clipped it in place ! Then, while removing the dried bracts, found a few mealy bugs so squished them and sprayed the entire plant with SPO !
Notice I said "picked up for another member" ?? I don't take freebies for myself anymore unless I see them first !!!
Sorry for the OFF TRACK !!! Good luck with your Gramma !!! BTW, is it the standard full sized kind ? Don't know if I said so but mine's a mini ! Variety kiilani.
