wild raspberries not producing
Hi we have wild raspberry or blackberry bushes. By boyfriend burns every spring and winter, although I have not allowed it the past two years. Still, they will not flower or fruit. I think, should I just mow them down, should I rip them out by the roots and start over? All of the wild ones along the roadsides do great. Should I just go along roadsides to pick my berries or keep trying at home? Thank you.
