Do you spend a bunch of money on yard care products every year? Well, is that really necessary?
This is what can be done with simply a spray bottle filled with white vinegar. If you don’t have white vinegar in your kitchen, you can also use table salt, which is also very inexpensive and has no unknown chemicals to add to the yard you and your family use all the time. Some people add dish soap like Dawn to salt and use that mixture.
Note that vinegar spray works particularly well if there is a lot of sun.
And if you want to go really low cost (zero dollars), use boiling water, but this should only be done if you can be very very careful. Remember, steam burns faster than boiling water.
Note that vinegar in a spray bottle can also be used to clean windows.
One drawback of this method is that you’re only killing the leaves off — you’re not killing the roots. But that means you’re also not putting harsh or unknown chemicals that are able to kill roots into your environment.
