Crabgrass is vulnerable to some home remedies, including dousing the weed with boiling water, sprinkling a small amount of table salt at the weed's roots, and pouring white vinegar mixed with soap on the plant. These solutions may impact the grass around the crabgrass without proper precautions.
Other easy home alternatives to commercial herbicides are corn gluten meal spreads and solarization. Solarization is a gardening practice that uses a sheet of clear plastic to effectively bake the ground, which kills annual and perennial weeds including crabgrass.
Crabgrass is a hardy weed that grows in over 300 different varieties in the United States. Its distinctive yellow hue, coarse texture and hairy leaves have been discovered in every U.S. state except Alaska as of 2015.
