Autum Bliss Rasp - Question on Rotation?

Hi aLl,

I ahve a rasp bed full of autim Bliss,  i have two questions for the panel!

1, Is there a time limit of how long a bed will stay productive, this summer will be the third year that I have rasps on the same plot, do i need to think about moving them?

2, Is there any benifit on digging up the older plants and replanting "new" off shoot plants, I remember hearing something about this, that the off shots are stronger plants?

Mine are on year 9 and still going strong.

Very nice to hear - i spent so long preparing the bed for mine i couldn't face doing it all again in a couple of years time!

My uncle had his raspberries in the same place for ever 

Each year he fed them with rotted manure and ashes from burning wood on his garden bonfire, and they just cropped heavily every year.

 No need to worry imho

My old next door neighbours when we lived in Kent had their raspberries in the same place for all the 22 years we lived there.  They always had lovely raspberries!
