You can plant in the Fall in zone 8a, but I would do it soon so the plant can put out feed roots, before frost.
Come thought Columbia, S.C. & I can give you 10-30 plants of the low "dew berry" type of red raspberry.They bare good with minimal water & no fertilizer or weeding.
Shameful that I know that, but I have so many & so little time.

Thanks, jolj. Unfortunately, Columbia is a couple hours away, but I appreciate the offer. Maybe someone else on here can take you up on it. :)
