Asperagus in hugels?

Hi folks. My hugels are doing well going into their 4th growing season. But a question has been plaguing me that I hope some of you can answer. How do you  plant asperagus in a bed that is constantly shifting/changing shape/needing mulch to fill in holes as the wood decays? Being this far along in the decaying process the beds have settled some. So I "think" I can safely plant something that will be a long-term established crop. But I would love to hear how you all do it.

I did it and it's been ok so far. I planted last year. The beds don't shift rapidly enough to have problems like that, I think the plants can adjust.

Hugels will settle the most within the first two years of building them, that's because the soil and other components are filling in spaces.
Once that initial settling is past, plant away, just remember that you will most likely get to add soil ontop of your asparagus crowns as this secondary settling occurs.
Asparagus is not nearly as fragile as many people think, I've seen it growing wild, in the wild and I assure you, "weeds" were around those plants as was grass.
I did some research with people that lived in the area and they said they didn't know where the asparagus would have come from and they had all lived there for over 50 years.
One gentleman said that the field I found it in had been pasture since he was a young boy (he was over 80), he didn't ever remember the asparagus not being there. (it turned out he was the only one who picked spears from that large patch)
