What do I do when my daylilies are dead? Do I dig them up or just leave them and plant more?
You can leave daylilies in the ground and they will come back next year. They are very hardy.
When is it the best time to separate your hybrid day lilies? Will it hurt to do it in the late fall?
These are the orange lilies commonly found in ditches and roadsides. I dig them up and they keep coming back please help!
I dug a bunch of them out from the roots and a good couple of shovels of the dirt out and gave them to a neighbor. She loves them and I don't have to deal with them any more!!
I have an old, established landscaping bed in the front of my house that includes a mix of perennials like daylilies, hostas and daffodils in addition to shrubs/small trees. We need to raise the bed, as it slants inward in spots toward our 90-year-old basement. How can I add several inches of dirt without killing the perennials? What time of year should I do it?
In order to prevent damage to your plants, it would be better to wait until the end of the growing season (probably some time in fall) before raising the height of your beds.

I have tried to deadhead promptly. However, there are many seed pods on my plants. The plants also seemed to bloom earlier this year, am I right about that? Can I remove the seed pods to get more flowers?
Most lily varieties do not rebloom, though there are some types of lilies that do. These would be listed as reblooming. You can, however, remove the seed pods and try your hand at planting the seeds, though they will take much longer growing them with this method then by division.
The stems on the more exotic daylilies are splitting. Thought it was a critter eating it but discovered when I put the damaged stems in water, that they split again while in the water?
It sounds like your daylilies are "scape blasting". This article will explain more:
