The things one learns from an allotment. I'm fairly certain this is what is afflicting some of our new raspberry canes. We planted them last year. One didn't make it through the winter. Another has had a tough start because the family man-with-strimmer keeps razing it to the ground when he powers by on grass-cutting duty.
