Caroline raspberry fall bearing?

pylot(usda 9b sunset 17)February 28, 2014

I have a Caroline raspberry patch. I've heard that it is mostly used as a fall bearing raspberry. However, in our garden, it has a huge harvest in June on old canes (seems to me, maybe 5 lbs from a 3 ft by 3 ft area), and then it barely fruits again in the fall. Anyone else noticed this?

1. Is this due to the fact that I keep long canes (5-6 ft tall) over the winter? It seems that the new canes coming up in spring don't get enough light before I prune the old canes in early July, so maybe this is why the fall harvest is practically non-existent.

2. If I were to totally remove all the canes in winter and get rid of the early summer harvest, would I get a similarly huge harvest in the fall?

Thanks for advice!

On Question 1, yes they lose some energy and the plant itself cannot concentrate just on new canes. It has to feed the old canes too. So maybe you would have a bigger crop if no floricanes. How much bigger though is the question?

On 2, not sure? I think you need to experiment. They say it should give you a big fall crop. But I think it depends on cultivar. My Fall Gold gives a decent fall crop if no floricanes, or if floricanes. So it makes sense for me to harvest both with that cultivar. I'm confused by the advice myself as I don't understand how 1/3 of the plants (fall crop) will produce more than the other 2/3 (summer crop).
My summer crops are huge!

If you want fall raspberries you need to prune all of the canes down in the winter.

I have Caroline in Nor Cal. Gives me fruit twice, cut the top 1/3 off the priomcane after it fruits. Cut the floricane the next year after it fruits. I'm sure the fall crop would be larger with no floricanes but I prefer longer season of raspberries.
