I grow almost all my daylilies in pots. In the short version of what I do, every spring I take them out of their pots and hack off about 1- 2 inches of their bottom roots with my little hatchet, so that I can refill the container with fresh soil and fertilizer. They do just fine. So your plants shouldn't have any problems if you take some of the roots off too. There are a few nuances to this if you like. For instance if you have to chop off any of the larger swollen tuberous roots, it might be better to take the whole root off up near the crown where the root narrows just so you don't leave a larger "sore" that could rot. I've seen daylilies with only a few scraggly roots hanging down that once potted up grew like gangbusters. They are amazing plants.........Maryl
