Hello Rob
May I suggest two other varieties that I have tried that performed
much better than Autum Bliss

Joan Squire ( an improved raspberry from the Joan J camp)
and Polka which harvested its last berries with the frosts, 2nd
November. Stood better than Autumn Bliss

May need to go mail order. The canes I got of Polka had roots over
3ft long, has proved to be a vigourous grower.

Good luck
