I have a 5 foot tall Fall Gold Raspberry plant. I bought it as a 4 foot plant from the local nursery earlier this year. It has been producing quite a lot of berries. There are perhaps 20 growing on this plant at the moment. The problem is that the fruit shrivels before it reaches mature size. Here is someone else's photo to show what a mature Fall Gold raspberry looks like:
All of my berries start shriveling at half that size. I have eaten them before they've shriveled and they are quite sweet and aromatic. However, I'd prefer to eat larger meatier berries. This is a photo of my my shriveled berries:
This is a photo of the entire plant. It is planted along a southeast fence. It doesn't get sunlight in the morning because the fence blocks the southern sun, but starting at noon, it can start sunbathing. The plant looks green and lush to me. It seems that the few burnt leaves are the ones that receive the most sun. I've been putting a tad bit of cottonseed meal to slightly acidify the soil.
It's now the middle of summer and my Fall Gold is producing its second batch of berries. This time around, the berries have remained green before reaching full size. The previous batch would become gold far too soon. Temperatures have been a tad bit more comfortable - 60 F at night, under 80 F during the day. I still water it every 2 or 3 days.
The lush cane closer to the camera is newer growth. It's producing some big berries. The sickly one in the background is the original cane from the nursery - the same cane that produced the immature shriveled berries. Even though it has become sickly, it's still producing a second batch of berries now. So I'll let it produce before sending it to the grave. As this is my first year gardening, I don't really know what pale and dried up leaves signify. I'm inclined to believe that it's a cane that's reached the end of its lifecycle.
