I offer daylilies in pots. Had been using compost with peat. They do compact and I have found the black pots getting rather hot in the summer just as Michele mentioned. BTW, Michele, this year I used compost and bought pine bark mulch, which I hope is what you call pine bark down there. I'll report if there is a difference for me, later.
Just as with daylilies left with their roots in water, one can see new white roots growing quickly in well watered pots!
With all the rain you had, Dick, I think that might have contributed to your increase.
Around here, I notice increase AFTER they bloom and start to put on new growth.
Oh, and for the winter, all pots get tipped on their sides or put under benches, which are boards of wood, with a tarp over them. The idea is to keep the crown dry for the winter so it doesn't freeze/thaw.
