Thinking ahead a bit, obviously, since there is about 6" of ice on my pond. My pond has been up and running about 1 1/2 seasons, so my lilies definitely have to be divided this year. It seems I can do this any time I like, right? Right now they are just a bit to deep in the pond to pull out and stay dry with my chest waders on, so I'd like to wait until the water warms up to where I'm not freezing. I also put in a lotus in about May of last year. Looking at the pattern of the stalks, it looks like it made its way all around the pot (24" maybe) but it didn't fill in the center. Does this need to be divided each year or can I wait a year or two still? When I do get around to dividing the lotus, can I put two tubers in the pot so it's not so sparse?
