I have two Anne gold raspberry plants that I feel are limping along. I ordered them as two year old canes and planted them mid to late spring this year. Shortly after sprouting and putting on leaves I noticed they started to develop brown spots. One of the canes did flower and produce fruit. I treated both canes with an organic insecticide to try and help with aphids and fertilized with a 10-10-10 fertilizer. Nothing really seems to be helping them with the brown leaves. They are watered regularly and recently we have been getting a lot of extra rain so I have not been watering. One of the canes did put on some new growth and is starting to bud. Any advice y’all can give would be greatly appreciated.

For example, fruited canes are usually cut down to the ground after harvesting. Didn't one of your plants produce fruit?
Everbearers bear fruit once at the tips of the cane then the tip dies. Afterwards, it bears fruit further down the cane then the whole cane dies. This happens within the span of two years.
Basically, you're trying to keep a spent cane alive that is naturally dying. What you should be doing instead is to prune off the dead and dying parts.
Incidentally, for an everbearer like yours, I usually cut off the cane at planting time and treat it like a single bearer to give it time to establish and become vigorous enough to support "everbearing". A good sign of vigor is if you get multiple canes growing from a single plant.
