My fire bush croton suddenly has droopy leaves on one stem. It was really dry and the app suggested watering tomorrow so I went ahead and watered it hoping it might come back to life. There was another stem in this bunch that suddenly wilted then eventually died so I cut it, but I don’t want another one to go. It seems to have new leaves growing so I assume it’s healthy. It looks like some roots are starting to come out of the drainage holes, so maybe it’s time to repot? I don’t see any signs of pests or disease but I’m also a newbie. Any advice?
