REALLY Killing Weeds With Vinegar

Outdoor Living 2 days ago
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.

    Used the straight1 gallon of white vinegar from Walmart with a tbsp of some dish soap. It took two applications a few days apart, but it killed the weeds in the aisles around my square foot garden boxes. That was in May. It is August and a few have

    Does the vinegar only kill the weeds? I ran across this post and it is new to me. I have spent countless dollars trying to kill different kind of weeds, and year after year no progress. A little input please. Also would love suggestions on getting rid of

    The recipe will kill plants as wells as weeds so caution is urged.

    I have to bring this up.......excessive weeds are often a sign that the soil is not healthy. Everyone has a few weeds, but healthy soil that is properly mulched has far fewer weeds, and better plants. Get off of synthetic supplements, use compost (you

      Angela C Excellent advice. And do get a soil test done before you add amendments! All states have an extension service that can give you a soil testing kit for free. The kits come

      Grace Barella I read that recipe, but it was Epsom salt, which is really Magnesium Sulphate, and the Sulphate acidulates the spray so it kills, and Magnesium is an essential

    I take boiling water from stove (or cooking water) and pour directly on weeds. Kills them dead for the season! Use the boiling water I would normally toss! Use this where weeds are 'grouped', not close to flowers and such.

    Just remember hat vinegar will also kill toads, your friends in the garden, so please be careful regardless of what you use.

    I had a large patch of English ivy in my front yard that I wanted to eliminate. I sprayed it with round up which barely had any effect on it at all and then doused it with their extra strength version (brush and tough weed?) which also had very little

    If someone is using 5% vinegar, and has been, and it kills weeds for them, How can anyone post how wrong it is and that 5% vinegar will not kill weeds? I use it, have used it for twenty years and it kills weeds. (NOT old tough Giant weeds, DUH) and yes
