Spring is in full force… birds are chirping, flowers are blooming, the grass is green (and growing fast as ever) and, unfortunately, weeds are popping up left and right – particularly where the bricks meet the driveway and the carport floor meets the asphalt…

Rather than going to the hardware store to buy weed killer, we opted to do a little research in hopes of finding a natural weed killer. After a bit of Google-ing, we found the most popular “natural weed killer” of choice was none other than vinegar. Vinegar is one of our cleaning bucket staples but we hadn’t thought about the possibilities of using it outdoors, much less as a weed killer. Apparently, the acetic acid in vinegar is what dries up and ultimately kills the weeds. Since vinegar is really cheap (only a buck or two per gallon), we figured we should give it a try.
Before we went spraying the entire perimeter of the house with vinegar, we decided to test the method where the carport and driveway come together. Here’s the before:

Before we show the after photo, here’s what we did: Obviously, we went out a bought a gallon of white vinegar. Next, we took an old Round-Up container, pulled off the lid, and rinsed it out thoroughly. Once that was done, we just filled up the container, pumped it up to the proper pressure, and went to town! It was really pretty easy. An old spray bottle would work just as fine.
Now, our results…

Okay. So this isn’t too impressive. There are several things that pop into my head as to what happened here: First, maybe there wasn’t enough sunlight (apparently this is a major factor in vinegar’s effectiveness). Second, maybe we didn’t use enough. The round-up container puts out a very fine mist; maybe we would have been better off just dumping some of our gallon container on the weeds. Third, maybe our climate is too humid for it to work well? Regardless, we’re going to keep testing more combinations and see what really works. We know it should work. It’s just a matter of finding what works for our weeds.
If you are planning on trying this remedy out for yourself, here are a few things to remember:
- The acidic acid in the vinegar is the “killing agent”. This won’t work for pesky weeds in the flower bed because it will probably kill anything the vinegar comes in contact with. Therefore, vinegar is best used as a weed killer in concrete, between pavers, etc.
- If used in direct sunlight, you’ll see the weeds start to brown an wither within just a few minutes. Larger weeds may take a day or so to fully die.
- Yes, vinegar is really smelly. Give it a few minutes and rest assured, the smell will go away (especially on a hot day).
How about you?… Do you have any natural garden/outdoor remedies?
