What you got was all the rhizome mass could support, keep it mulched
a few feet around and next yr shoud be better.

==================================================

Thanks, are you saying that in addition to retaining moisture and
protection weatherwise (mostly in winter) the mulch plays some
kind of mechanical support function for the young shoots and their
rizomes.

If this is correct the mulch has to be very, very deep.

Which depth would you recommend?

Before failing my new shoots this spring were fairly "large"
(half inch or slightly less in diameter and about 2 ft *high).

BTW I am more or less your neighbor (Putnam Cty, NY).

The mulch does everything but offer mechanical support. Aborted culms
are a natural occurrance but it sure does tease the grower!
4" of mulch is usually sufficient and as it decays your soil improves.
