It's a young plant and the larger canes died over the winter. So, the stalks are short and the entire stalk is wilting/dry. I see no sign of cane borers based on the pictures I saw online. Thanks for the idea. Does anyone have any other ideas?

I'm not sure what is going on? It could be delayed winter damage. Were they in ground? TC is not extremely hardy. It usually can live in 5, but canes may die to the crown. Hopefully your crown is still good, and just the cane is no good. Any new canes growing? I would not remove it just yet,

Gophers or moles?

Once in a while a cane will break at the union where it comes off the main plant.

My blackberry is dead. The branches dried out completely and I see no sign of life at the crown. I'm planning to plant a new one nearby and will try again. I will leave it just in case, but can't believe it can survive with no leaves or green. I have no idea what happened. I examined for signs of gophers and moles and found none. I see no break in a cane. I don't believe it was winter damage since these were the new shoots, not the older ones, which I do believe died from winter damage. The young parts of the plant just wilted and completely died overnight. Would a spray early on protect the new one? What one?
