Winter care of TC blackberry, raspberries too
Hi, I've searched and can't really find how I'm supposed to get my primocanes through the winter to bear next year. I planted 5 TC BBs, 5 Killarney raspberries, and 5 Encore RB (only 3 made it, but I've got some suckers I can move to those spaces) in early May this year after the April freezes were over. The RBs have suckered pretty nicely, I did get a few fruit and know I can prune those canes off now (and cut the original canes even if they didn't fruit). The TC grew 6-7ft long, I tried bending them over and tip-rooting but only 1 seems to have rooted - not sure what I can do with the other 3-4 long primocanes at this point.
They're in raised beds, with bark mulch (decomposing/sliding off the slopes) right now, should I put burlap down for winter (removed when I started seeing suckers)? Cover with old hay? What about the canes? I can lay the TC PCs down, they're so long, but they do grow straight up for a couple of ft b4 they start curving, I also don't want them to root all along the length if I lay them down to cover for the winter. And of course the RBs are erect, I can't lay them down.
Put up hoops and cover like a low tunnel for the winter (so snow won't break the canes)? What can I cover them with that will keep them warm enough if hoops are 2-3ft high?
Not trellised yet - figured we could build trellis next year, didn't expect TC canes to get so long the 1st year.
