Lots of unripe blackberries but branches are a brownish color
Hey there, I have a year-old blackberry shrub, the type that does not need another for pollination. It produced a few berries last year although it was new. Now, it has a better crop of unripe berries, but I am a little concerned about the brownish color of all branches with fruit. Even stranger is the tall erect portion of the plant which does not contain any berries but is strong and green as can be. It almost looks like something foreign (we get a lot of trash trees around here!) but as far as I can tell, it is indeed part of the berry plant. I pruned correctly (I hope) this spring. I don’t see any sign of disease. I’m just wondering is this normal? Let me show a photo... Not a real good one but you can get an idea of what it looks like. - Thanks

It appears normal in that the plant is growing it's primo canes.
This link will explain this.
Looks like a wonderful crop of berries!
