Hi bramble lovers-
I started a bramble patch with black raspberries a few years ago. Last summer was its third summer, and its first with a yummy and productive batch of fruit. I pruned it as recommended in the early spring and early summer (I have a brambles pamphlet, and the AHS pruning book and the Fruit Gardener's Bible). Unfortunately, I was traveling a lot in the late summer and early fall, and neglected the patch. Several of the canes quickly grew long enough to arch over, in some cases with the tip reaching the ground and rooting. In late fall, in hasty prepping for the winter after the first hard frost, I did clear out old canes, but I didn't know what to do about the arches, esp. the ones that rooted, and I just left them.
Now it's early spring, and I don't know what to do with the long arches, esp. the ones with rooted tips. None of my resources cover this. I'm guessing I should prune back the large arches to a few feet tall. Is this right? And what about the rooted tips? Should I dig them up? Can I prune those arches so each end is now its own plant?
I can provide an image of the patch (I tried here, but as a new user I couldn't share the URL in my first post).
Have mercy on this repentant bramble neglecter, and guide me!
