There are some small roots that are being damaged. Can't help from that, but it has been very little. I keep the plants well watered, and I don't fertilize with anything other than alfalfa pellets and sometimes seaweed fertilizer, but I haven't used the seaweed since the Spring. When you said that there wasn't enough root left, I assumed you meant the entire root was mostly gone. That isn't the case at all with my daylilies, so it made no sense to me. If you were talking about the very small roots, I can see that being a reason with mine, because a few of them are being pulled off, but there are still a lot left. All of my daylilies were moved here two years ago, so the roots aren't all that spread out, like they would have been after many years in the ground. So, I really am able to get almost all of the roots dug up with very little disturbance. But, I'm not 100% successful.
