Let me preface by saying I know they’re classified as a noxious weed here in Australia, I’m not intending to propagate them, and I promise to remove and destroy any seedlings that appear in my garden.
Moved to a new house a couple of months ago which has a magnificent blackberry thicket in the backyard. February of course is the time for picking the little bombs of goodness, and the grandkids and I have been picking and eating and freezing them like crazy.
I want to know when and how to cut them back after fruiting is over. Do I wait until winter and full dormancy, or can I cut them back straight away?
Do I cut the fruiting canes, or prune back the new ones that have sprung up all over the place? They currently cover an area of app 4m x 1m…can I continue to keep them in this space without reducing their fruiting capacity over time?
Thanks in anticipation.
