I am fascinated by this concept - do d/l's in cooler climates pull themselves deeper, too, or does this occur more often in warmer areas?. I am forever "lifting" daylilies but, like Tina, live in an environment that gets scorching hot in the summer (115+ degrees).
Regarding the moats, it may be what I am seeing in the open ground is related to "moat wash-out" but it seems that the d/l;s are deeper than their neighbors when planted in the garden = and everyone is subjected to the same mulching practices. I do "re-moat" each time I mulch which can be as frequent as every 6-8 weeks over the spring and summer as we have an extremely active earthworm population here. We currently go through 8 to 10 or more inches of bedding/rotted manure every month and half or so until it cools down. It seems to me, though, that the d/l's are deeper than mulch decomposition would account for as the soil I pull back from them is heavier and denser than what I typically see when bedding breaks down.
I recently pulled a Johnny Cash fan out that was extra-large and it, too, was anchored particularly deep in its pot. Is the habit of "pulling down" a mechanical function (ie, more support for larger fans)?
