I would say, “If you can’t beat ’em; join ’em.”
However, my philosophy for the blackberries in the front yard bushes is: “If you can’t beat ’em; EAT ’em!”
I have been trying to get rid of these “brambles” for years. Countless yards of prickly vines have been pulled up carefully and discarded. Now I have pretty roses with blackberry vines intertwined in them.
This year, I did not get to the annual exercise in futility, and it is resulting in a small harvest.
I’m just going to eat them.
