Homemade Crabgrass Killer

By Kenneth Coppens ; Updated September 21, 2017

Crabgrass is one of the most common weed problems in North American lawns. It germinates in early spring and quickly reproduces and spreads throughout the summer. There are many products one can use to control crabgrass, but they can be expensive or even have chemicals that are harmful to animals and humans. The most simple technique for crabgrass control can be prepared at home. The only ingredient needed to get rid of crabgrass is perhaps the most abundant material on earth.

Fill a pot with water and set it on the stove. Set the stove to high heat and bring the water to a full rolling boil.

Take the water outside as quickly as possible. Pour the hot water slowly on the crabgrass. Keep in mind that the hot water will likely kill any plants it comes in contact with, so do your best to pour it only on the crabgrass.

Repeat the process as often as necessary. It may take three or more attempts to kill fully matured crabgrass with this method.


Things You Will Need

  • Pot
  • Stove


  • The earlier you catch the problem, the easier it is to control. Try to catch it in early spring or sooner.
