REALLY Killing Weeds With Vinegar

Garden Stuff Yesterday
For more details on this process, please visit the blog post below.

Lately, I've been seeing Pinterest boards and blogs with tutorials on how to make a vinegar weed killer. Friends, I'm here to tell you that their information is faulty and their vinegar weed killer will not work.

Most of the blogs that show vinegar weed killer recipes, show household vinegar with 5% acidity.

This.Will.NOT.Work. I repeat, This.Will.NOT.Work.

You need a vinegar that has AT LEAST 10% acidity PLUS a horticultural citrus oil. There is some controversy within the organic gardening community regarding vinegar strength. Very respected gardeners say that 10% acidity mixed with citrus oil will kill weeds.

For at least 10 years I have been using a 20% vinegar for my weed control. I have not tried 10% vinegar ~ but I trust the gardeners who say it will work. Many of them are diluting their 20% vinegar by cutting it in half and adding water. Doing this will give you two gallons of 10% vinegar.

  • Household vinegar will NOT kill weeds. Read how to REALLY kill weeds with vinegar.
  • You need at least a 10-20% vinegar plus horticultural orange oil (or other citrus oil)
  • You need to apply it with a spray bottle when the sun is bright, the ground is dry, and the temperature is above 70-degrees.
  • This type of sprayer will tackle larger jobs.
  • There are a few companies that have pre-mixed the strong vinegar solution with a citrus oil.

    I use whatever type of vinegar happens to be available or on sale and mix about 2 cups with a couple tablespoonfuls of salt and a couple "squirts" of dish washing liquid. Works beautifully -- and I don't "spray" the plants. I POUR the mixture over the

    I also am wondering where to get 20%? I will try the regular cause I already bought it,but I will also try the 20% if I can find it. How long before I can replant some things in the spots that I sprayed?

    Thank you for all of your comments. Sharing is how we learn. I have tried all of the household vinegar recipes and they do nothing to my hill country weeds. And, I don't know a serious gardener who has had any luck with it, either. The weeds pop back up

    I just cleaned up the dead, dry, shriveled up weeds that I had applied straight white vinegar to last week.. I had poured it on them and saw an almost immediate reaction. I really love it because I can get rid of the weeds and be "GREEN" about it!
