Yes, I’ll admit the scene is a little odd, but I am putting into practice my philosophy on gardening: use natural remedies before resorting to chemicals. All of us know of the dangers of chemicals in the environment. We all carry around residual bits of the poison in our bodies. An effective way to kill weeds that sprout in sidewalk and driveway cracks is to douse them with boiling water. If they are especially tough add a touch of salt. The weeds instantly wilt, dry up, become brown, and are gone in a day or two. Easy! All you need to do is put the kettle on!
