If you've been struggling with weeds, a propane torch is about to be your new best friend. Torches target the weed itself, zapping the plant's moisture and killing it right away.
Once you see it wilt, resist the temptation to yank it out because it can spread the weed's seeds. The best time to torch your weeds is when there's some moisture in the air.
It is also good to avoid doing the task on a windy day. Be mindful of the type of weed you're trying to destroy, since if it's poisonous, it's not good to inhale the toxins.
