I don't know it this pertains to this post or not, but I'm 78 now and it is too hard to drag a hose around and water now. All my daylilies are in the big pots. For drainage I put the pot 1/3 full of big bark mulch on the bottoms ,then mix potting soil half and half with fine bark fines to plant in, then mulch on the tops. I made myself a daylily area with sprinklers on the corners. I paid someone to do this for me. The ground was lined with barrier with gravel on top. This has helped me be able to continue gardening at my age. Now all I have to do is go turn on the sprinklers to water my pots.Here are some pictures.
