I'm zone 6 here..
I have 1 heritage raspberry and 1 ever bearing raspberry. I picked some fruit off it yesterday....lol
I will stay tuned in to this...I have no idea either.

You want to wait until they go dormant... I would wait until the first frost. For me here in zone 6, I usually mow my beds when I do my last round of leaves for the season.... usually around December 1st. -Glenn

Wait for them to go dormant. Right now, the leaves are gathering energy and storing it in the root system for the winter.

Your plants will survive the winter better and come back stronger in the spring if you wait and cut them when they are dormant.

Hi oregon is that basically include every plant like apple trees too that shed their leaves to go dormant. They are storing energy in the roots...taking away from the leaves?

Thanks so much, Oregon and Glenn Russell. I knew Gardenweb people would come through. And I will wait until after the first hard frost.

I wait and do my Fall bearers in the middle of winter when there is little else to do garden wise outside, helps with the winter blues.
