Hello - I have been trying to find a picture of what sunchokes look like when it's winter. Do the stalks die back or do they remain somewhat hedge-like?
Here, they dry down brown and brittle and mostly disappear under the snow. But I just looked outside and there are clearly a few spiky stems emerging from the two feet of snow and standing proud another 3-4 feet.
I often cut sunroot stems off shin high before winter arrives. Cause the snow and wind can lever them out of the ground, then the tubers get exposed to the elements and go bad.
