Saturday I started an experiment to see which of the Seven Deadly Homemade weedkillers would be the most effective at killing weeds along my fence line. I started with Bleach and you can see the results here.
On Sunday, I tried vinegar. I mixed 3 parts of vinegar with 1 part of water and sprayed liberally on all of the foliage. The sun was out and it was hot which should be the best conditions for killing weeds. I did spray some different weeds this time to see if it had more of an effect on one type of weed than the other.
As you can see in the picture above, while the foliage is not exactly looking happy, it is not dying either. I will take more pictures in a few days because one of my readers suggested that it might take several days as it does with Round up.
I tried it on this huge thistle and although it does not show up well in the picture, it did turn large spots on the leaves brown. I would say it probably made about 50% of the leaves brown.
Now where I did have a great deal of success was with the grass growing up between the bricks. I sprayed the line of grass on the right with bleach and the line on the left with vinegar. While both are turning yellow and dry, the vinegar line is definitely dryer and yellower.
So far, results are disappointing with both types of weedkiller for my uses but it does look like you might be able to use either of them for killing grass in the garden or the driveway. I did not have much success with the weeds along the fence line. I guess today I will try cooking them with some boiling water.
