“Do blackberry brambles need to be mulched for the winter? Mine
are varieties that are “hardy” but I wonder if mulching the the plants canes
and all would be helpful.

Thank you for the email regarding your blackberries. It is okay to mulch blackberries, but it is not necessary. To be honest, in my garden at home, I do not mulch the canes. If some leaves blow in and get caught in them, I usually leave them there, but I don’t add anything beyond it. I have a good crop of berries each year.
One thing to keep in mind if you do add mulch is that the mulch may provide a nice overwintering hideout for mice, voles, and other vermin that may see your canes as dinner. When blackberries (or for that matter, any woody plant) is mulched, there is a higher risk that animals may chew on the canes and/or girdle the canes.
I hope this information helps you out. If you have any other questions, please feel free to ask.
