Very true. Often when they get that large, if I am not intending on selling the plant at all, I will just take a shovel and go down through the middle of the clump and remove half of it. They can be very difficult to divide when 30 plus fans, especially the tetraploids.
I might add, very hard to divide, especially if you have a lot of clay like I have. I imagine a sandy type soil is much easier to divide. I know my daylilies that are close to my spruce tree where the soil gets a lot of organic material like pine needles falling, they are really easy to divide. The soil is loose and airy and no problem at all. I wish all of my soil was like that.
