After I cut my bamboo down, can I kill it by torching the short remaining 3 - 4' of stalk and torch the ground on top where the stalk bases were? Or do I have to cut the stalks down and then remove as much roots and then torch the root area. I was thinking heat would be a good method and if I only had to torch the stalks it would take care of killing the roots too. I torch grass and it kills the roots right away.

Torching the plant may only help it thrive more and isn't likely to kill the root system. If you're looking for ways to eliminate bamboo, this article may help: https://www.gardeningknowhow.com/ornamental/foliage/bamboo/kill-bamboo.htm
