My Pilea has been suffering and I’m trying to talk myself into chopping and propping. When doing so, should I cut the top part (with leaves) off, cut a section of the stem off, and then leave the bottom part of the stem in the soil? Also, is it better to let Pilea callus over before placing in water or do they prefer to go straight in? (The brown/black leaves have been removed. I would probably cut where the straps are placed)
