Too frequently, you need to rid an area of weeds or unwanted grasses. Most gardeners will reach for some type of herbicide that they can purchase at any garden center. These, however, can be relatively expensive over time. They also contain chemicals, many of which can actually be harmful to the environment. Making your own herbicide is much less expensive and also, by using all natural materials, not harmful to the environment. Actually, such homemade herbicides tend to be even more effective than the chemical-based herbicides currently on the market.
Method 1: Vinegar-Based Herbicide
Stir the salt into the vinegar until all of the salt is dissolved. Vinegar is a natural herbicide, while salt discourages weeds from returning. You can use any type of vinegar and salt.
Add dishwashing liquid. Dishwashing liquid enables the mixture to adhere to the leaves rather than just flowing off the weeds.
Pour into a spray bottle and spray directly on the weeds. You can also use a small paintbrush if other plants are growing near the weeds you are trying to eradicate. By using the paintbrush, you do not risk getting the mixture on your other plants and killing them, too.
Method 2: Boiling Water Herbicide
Bring the water to a boil. Boiling hot water will kill weeds and unwanted grasses.
Stir in the salt. Salt, as previously mentioned, keeps weeds from returning.
Pour immediately upon the desired area. Do not pour around plants that you wish to keep. Use this for such areas as cracks in the sidewalk or large areas you wish to rid completely of weeds or grass.
