I think this is my third year since I planted 2 darrow blackberry plants. They produced fruit the 2nd year, but I either think the berries shriveled up or the canes died. They have produced a lot of fruit this year but I am afraid the same thing might happen this year. The plants look very healthy and prolific. For pruning, I have been tipping the new canes in the summer down about a foot and cut off the dead wood in late fall. Would I be better off just cutting them all down and only have 1 crop? What are your opinions on this? I can post pictures of the plants if that would help.
