Is it ok that I left my lilies "au naturel"in the ground? Was I supposed to cut them back when they were done flowering? I just left them alone and now they are getting very ugly and brown. I realise the fall is coming, so is this what they are supposed to do, or should i cut them and how much if so? I'm talking about oriental lilies, but I also have day lilies (miniatures), so I guess I need to know what to do about both types. Thanks so much for any help!!!
