Hey, just have a question for you all, i've had a bunch of lilies in my pond for the last few seasons. They were planted in a planter and doing fine, this spring i decided to separate them and i've already put them back in and they seem to be doing fine. My question is, do I have to put them in pots or can i just bury them in the bottom of my pond? I seem to vagily remember someone saying they need to be potted or else their roots will go right through the pond liner which would be horrible in my case. Any ideas?
