Weed Killers: Vinegar, Salt, & Dishwashing Liquid vs. Boiling Water

First of all let me tell you I am in no way a gardening expert. And if you saw my yard, you would agree. I am a novice looking for a gardening angel.

One of the problems I currently have is weeds popping out all over the place including on the rock path that borders the house.


We thought placing rocks in our yard meant less weeds. But that’s not the case.

For  years, I’ve been weeding this area by hand but I seem to be losing the battle. And because we have pets, pesticides are not an option.

Then my co-worker told me about a weed killer his wife used on their side yard of vinegar and salt. He said it worked very well.

I did a little research and I found out that many people use this vinegar and salt concoction but with dishwashing liquid added. I also found another option that intrigued me: boiling water.

Yup, plain boiling water is a natural weed killer. It has the added benefit of being free (besides the cost of electricity to boil the water) and salt-free, because adding salt to your yard changes the chemical balance of your soil.


I decided to pour boiling water to the left side and spray the vinegar, salt, & dishwashing liquid to the right side.


The next day, there is a dramatic decrease of weeds. The left side with the boiling water worked a little better but both sides have less weeds.

Be careful. Boiling water is dangerous. Instead of carrying a pot of boiling water to your backyard, I suggest transferring the hot water to a metal watering can which is much easier and safer to carry.


Slowly, I’ve been pouring boiling water on the rocks to take back my yard. What do you do to combat weeds in your yard?

    I have used the vinegar,salt, and soap technique. It works well on tough plants. I have ivy in my yard and it is very hard to kill. That mixture was somewhat effective on the ivy.

    Typically I try to pull as many of the weeds as I can. I am currently throwing the plants in my compost.

      It’s great that you found something that works for your yard. Weeds are a constant battle. Wouldn’t you rather be planting herbs or vegetables than weeding? That’s the fun part of gardening. Thanks for writing. Happy gardening!

    Ive got to give this a try… The weeds are definitely winning in my yard. Does this kill them completely down to the root or just the leaves and stem?

      Great question! I was just looking at my backyard yesterday and the weeds have not yet appeared in the area that was treated with boiling water so I’m thinking they are gone for good! Good luck with your yard. You can do it!
