pruning purple and red raspberries
I've tried searching the board for advice and also read online, and I'm confused by all the conflicting opinions.
I have a bed of Royalty purple raspberries and a bed of (I think) Prelude red raspberries. Got heavy yields from the purple raspberries last year, less heavy from the Preludes (which I'd cut to the ground last spring to get a fall crop). In the fall I cut out all the floricanes and did some thinning of the remainder.
Question: how should I prune each of these varieties, and when? The purple canes are now 3-4 feet tall, the red canes are 1-3 feet tall.
many thanks, Laura
