3.  Salt

Salt is a great way to kill plants but you need to be careful as it will kill everything, including your veggies, if you use too much. Too much salt will also prevent future plants from growing for a period of about 6 to 12 months, so this is best used in places where you never want plants, such as driveways, sidewalks, and patios. Fill a spray bottle with very warm water and add about a ½ a cup of salt. Spray liberally.


4. Rubbing Alcohol

This sucks the moisture from plants, killing them fairly quickly. Fill a spray bottle with water and use several tablespoons of rubbing alcohol and spray the weeds well. Be careful not to overspray onto any plants that you want to keep!


5. Boiling Water

This is the cheapest and simplest method of all! It also happens to be one of the most effective. Again, be careful not to let this touch any plants you intend to keep. This works best in places where you don’t want anything to grow such as driveways and patios, but used carefully, it can be used in gardens. Simply boil water and pour it over the weeds. This should kill them completely within 24 hours unless they are really large weeds. In that case, a second application should do the job.
