I was about to water my arrowhead plant until I noticed that one leaf had soft and sort of brown area on it. I wondering if this could be root rot? I also wanted to note that this arrowhead does need to be repotted since it not only has two of it in one pot but they’re both getting very big. Should I hold off on repotting so I don’t cause anymore stress to it or should I look further at the roots to see if it has root? Or I should I not be worried at all? I would be surprised if it had root rot since I try to wait as long as I can until the soil is close to or is completely dry.
