Many common weeds that grow through the cracks in your sidewalk or driveway can be killed by applying boiling water. This method of weed removal is especially effective against annual weeds, such as meadow grass, groundsel, creeping wood sorrel, chickweed, and willow herb. Some perennial weeds with long taproots and broad leaves, such as dandelions, thistles, mallow, and dock weeds, may need additional treatments. Boiling water also works for small-scale weed control in the yard. Pour the water directly on the weed, and re-treat in 7 to 10 days. This approach works best for newly emerged, lightly rooted weeds. To protect desirable plants, pour carefully.
