Synthetic herbicides are toxic, not only to the weeds they are intended for, but also to soil microoganisms, beneficial insects, animals (including humans), and our water supply. They are also unnecessary. Weeds can be effectively controlled by manual weeding, cover crops, and mulching. The last two do double duty by also improving the soil. On a small scale, boiling water can work wonders; boiling water with salt added can help prevent weeds from growing in paths and driveways.
