Awhile back I was having an issue with my peace lily... the leaves were yellowing. I read somewhere online that perhaps it was getting too much water, so I cut the stems down to the base as suggested. It was doing fine (still no new blooms) but now, It has another problem with a clear sticky substance as well as brown/tanish colored spots everywhere on the stems and the back of the leaves! Is there any hopes of saving it? I don't know what to do with it, but it has sentimental value because it was a gift from my father-in-laws funeral. Any suggestions?
