I did a huge chop and prop last year on my Micholitziana. When I repotted, I didn't cover the entire stalk with pon because I wasn't sure if it would get stem rot or not. She is starting to grow so my question is:1) Should I just fill the rest of the planter up with pon to help her develop more,stronger roots. OR 2) Do I gig her up and just fill the bottom with more pon and let her develop roots that way?
