DIY Weed Killer


With the increasing controversy surrounding the health effects of glyphosate, why not skip the Roundup and try this 100% natural weed killer?
Many DIY weed killers use white vinegar. I have found our weeds to be too hardy for white vinegar. I have had better success with horticultural vinegar!
White vinegar is a 5% acetic acid compound while horticultural is a 20% acetic acid product. White vinegar is obviously much cheaper, but I have found a little goes a long way with the 20% solution.
You can also dilute the 20% with an equal amount of water to create a 10% solution. (10% may be enough for your weeds.)
Recipe:
-2 cups horticultural vinegar
-splash of citrus oil
The citrus oil contains d-limonene, which naturally strips away the waxy plant cuticle, adding to the dehydration of the plant. (I don't use my expensive orange or lemon essential oils for this. I like this affordable natural orange oil.)
Blend the two in a spray bottle and apply directly to weeds. Be sure to spray only the plants you are seeking to eliminate as this will kill any living plant in its path.
(See my blog post for a second recipe using liquid castile soap!)

    Amazon has 30% horticultural vinegar. I dilute it a little (by a third) and add a little dish soap to help it stick to plants. It works faster than round up.
