Anyone have an experience in how deep can leftover sunchokes in the ground can be mulched without giving them problems coming back next year.
I've left mine overwinter, in ground in Vernon, BC. The patch doubled in size this year.. I plan on digging up after frost to check in on them.
Likely leave a healthy group in garden to double up again. They have been very good at habitating a dry corner of the garden bed.
Wish they would actually flower before the frost! Do any of the other varieties flower earlier? I think I have white stampede variety. Started with three. In 2 years the growth has been exponential.
Should be be a gastro adventure this winter!
