While there are many different recipes out there for a natural weed killer most of them are based off the following ingredients.
1 gallon of white vinegar.
1 cup of table salt.
1 tablespoon of liquid dish soap.
Mix everything together making sure the salt is completely dissolved. You can then pour this into a spray bottle or one of those weed sprayers you can get at any garden center. You spray this solution directly on the weeds you want to get rid of preferably on a hot day. One thing to remember with this solution is to not get it on anything you don’t want to kill and don’t spray it on the soil. It is non-selective in what it kills meaning it will kill any plant life it comes in contact with and it will sterilize the soil for up to two years depending on how much you get on the soil.
If you don’t want to spray this natural weed killer solution near your desirable plants you can wipe the solution on the leafy surface of the weeds you wish to kill with a cloth. It is advisable that you wear rubber gloves to do this as the vinegar solution is acidic and can burn sensitive skin.
