I got my monstera a little while ago from a friend and kept it in water for a few weeks but noticed a leaf starting to turn yellow and was told to put it in soil but it still isn’t thriving. I watered it recently and it is sitting on my dining room table a few feet from the window. When I repotted it I noticed it had a small amount of black on the tips of its roots. I know they can go in shock but I’m just wondering what else it could be?
