Although weeds are different things to different people, one thing is universal: if it’s a weed, you probably don’t want it around. I’m not super concerned about eliminating every weed, especially since many of them are actually beneficial. But I prefer that they stay out of the garden and out of the patio cracks.
Unfortunately, commercial herbicides are quite nasty. Glysophate (Roundup) is a particularly hot-button topic, as you’ve no doubt heard since all of these Roundup lawsuits started popping up. And while others aren’t getting the recent press, they’re no less worrisome. So if I can find a natural weed killer that works, and I can spray it while the kids are right next to me, I’m all in.
