Today I had a great time with one of those garden flamers frying the blackberry vines which are taking over the planet (starting with my clearing). Now I know how a superhero feels...ah, the POWER! But I'm wondering, did I just do the equivalent of a pruning only ("Thanks," said the vines, "we needed a haircut!") and is it really only going to strengthen the roots? Have I simply broken up the long vines into many enemies to sprout again another day, like a Hydra?
