What is wrong with my raspberries?

Bruce Hansen
last month

My June-bearing raspberry patch has consistently had vigorous primocanes, but the next year after pruning I find that the crucial floricanes are pathetic and bear little fruit. Also this year I have noticed some yellowing in the leaves of the primocanes.

Notice how in the photo below the primocanes are yellowing while the floricanes are barren:

Meanwhile, just a few feet away in a different part of the patch, the primocanes are flourishing, while the floricanes are still suffering (at least there are a few berries over here):

So two questions:

1. What is the yellowing a sign of in the first photo?

2. How can I get better second-year floricanes after a strong first year?
