Homemade vegetation root killer

Updated March 16, 2017

Unwanted vegetation and weeds can make a lawn or a garden unsightly and it can stifle the growth of your real plants. You could go out and buy a commercial weed killer, but other options are available. Homemade vegetation root killers are easy to make and are inexpensive. Kill the root of these plants and your garden will perk right up.

Salt and Vinegar

Salt and vinegar are natural weed killers; the acidity in the vinegar and the chemical compound in the salt work to remove moisture. While each separate ingredient could be used as its own root killer, if you put the two together, you will have a potent vegetation root killer that will essentially dry up the roots of the weeds. Simply mix 1 1/4 cup of salt with 1 gallon of vinegar. Mix well so that the salt dissolves into the solution. When you need to kill some vegetation, pour the mixture into a spray bottle. Spray the weeds at the soil. The solution should kill the root and therefore kill the vegetation. Be careful when using this solution; it will kill your good plants as well. Spray only where you want the vegetation to die.

Boiling Water

Believe it or not, but simple boiling water is an effective weed killer, according to The boiling water works to kill the vegetation's roots by essentially cooking the vegetation in the ground. All you have to do is boil some water and pour it onto the vegetation that you wish to eliminate. Be careful when you pour the water; it is hot and might spill on your hands.

Bleach and Rubbing Alcohol

In addition to the above methods, you can use bleach or rubbing alcohol to kill vegetation roots. To use either solution, mix a little of the bleach or the rubbing alcohol into a spray bottle and dilute it with a little water. Just as with the other two methods, spray the solution onto the vegetation, near the roots. Whatever you use (bleach or rubbing alcohol), the solution will kill the vegetation's roots. You need to be careful if you use these methods. The chemicals are not selective and will kill other plants besides just weeds or unwanted vegetation. The best way to use this method is to use the formula sparingly. When the vegetation is dead, wait a day or two before planting new plants in the same spot.
