I have had my plumies outside for a while now and one of them is blooming! but the one sitting next to it accidentally had it's inflow chopped off when my family member dropped something on it, it still is outside with nice, big, green leaves. But today I noticed that just above the soil line my stem has a noticeable yellow spot and it's wrinkly... It's not soft or squishy, and it is the only spot on the whole thing that is like that.. I kinda just moved the top of the soil around so it wouldn't be near the spot 'cause for some reason that seemed like it would help haha.. Any ideas?
