Detailed Description

To use this vinegar for non-selective weed control, mix 1-2 oz. of orange oil and 1 teaspoon of liquid soap per gallon of 10% vinegar. If your water is alkaline, add 1 tablespoon of 50-grain (5 percent) natural apple cider vinegar to each gallon of water to improve the quality of the water for potted plants and bedding. This doesn’t have to be done with every watering, though it wouldn’t hurt. This technique is especially helpful when trying to grow acid-loving plants such as gardenias, azaleas, and dogwoods. A tablespoon of vinegar per gallon added to the sprayer when foliar feeding lawns, shrubs, flowers, and trees is also highly beneficial, especially where soil or water is alkaline. The other horticultural use for vinegar is the watering can.

Weeds can be controlled with non-toxic products.   Forget using black plastic, toxic chemical herbicides, salt and bleach. Remember one of our primary rules – do nothing to harm the life in the soil. Bleach and toxic chemical herbicides are poor choices, but there are some good ones.

To keep the weeds out of a decorative or utility gravel area, the best approach is to design them out from the beginning or use organic products later to kill the weeds. Salt, toxic herbicides and bleach should never be used because they contaminate the soil long term. They also leach into the water stream. To head off the problem, install the gravel in a thick layer – 6-8” after scraping away all grasses and weeds.

For additional control, add a layer of white caliche rock before putting the gravel on top. Any weeds that grow through the gravel can be sprayed and killed with a mix of 10% pickling vinegar mixed with 2 ounces orange oil and 1 teaspoon liquid soap or you can use commercial organic herbicides. There are also commercial products now available.  Vinegar sprays can also be used to kill weeds in the cracks in sidewalks and driveways.
