I tried searching for my answer but I couldn't find anything directly related. I am in the process of redoing my waterfall and I pulled up my planted lily and I also found this growing outside of the pot! The root system is very big for my small pond. I will readily admit that I have kinda neglected things for the past year because I knew that I had to redo a lot. But if I wanted to separate and replant this lily how would I go about it? I have an arrow pointing to a part of it that I have no idea what it is, and the other circled areas and the new growth coming out. Thanks for any help I might receive.
