How to save both plantings?
My great-uncle has a large blueberry patch that until this year had been mantained by his DD's fiance. A number of years ago, uncle had planted raspberries in there too, but fiance always mowed them down in May/June. Now fiance is soon-to-be ex, blueberry patch is overgrown, my dad has cut chest-high weeds down between bushes and raspberries are bearing, great-uncle has enjoyed a couple pints. But they're growing in with the BB, hard to pick either, and I know if we don't cut them down they're going to take over.
So how do we manage this? I was thinking if I cut floricanes down to the ground after fruiting (as normal) and then this fall dug up as many primocanes as possible and moved them to new location, prune BBs more severely in that area this winter so we can access RB next year, repeat picking/cutting/transplanting, that maybe we can eventually get the RB cleared out of the BB patch and moved to another location so uncle will be happy?
