It’s time to clean up the bramble patch. In order to maintain healthy and productive blackberries and raspberries, we need to prune out the old to make room for the new.
Most brambles are biennial, which means they fruit on second-year growth.
Blackberries are easy to deal with, just remove the arching canes that fruited this year and trim up and trellis the new growth from this summer, which will bear next summer’s fruit. Repeat the same thing next year.
Biennial raspberries are trickier.
