Help! A couple of days ago, I repotted Irish Iridescence. I took it out of its pot, gently scraped the outside of the stem that had been above the potting mix, cut off the bottom 1/3 of the root ball and replaced it back into the pot. I added potting mix to cover the stem close to the bottom row of leaves. I sprayed the plant to clean it off, and some water got into the pot, which I thought nothing of, since the new potting mix was dry. The next morning and today, the bottom row of leaves are very limp. The others are okay. What happened? What did I do wrong? I've repotted other plants similarly, with no problem, but I think this is the first time I scraped the outside of the stem that was sticking up above the potting mix. Could it be root rot from too much water? Would that have shown up so fast? Is it shock from cutting off too much of the root ball? What to do? This is one of my favorite plants - a constant bloomer and very pretty. Thanks.
