Natural Weed Killers

Here are some suggestions that people have suggested to me on how to kill weeds in your yard, along with taking care of fleas, beetles and ant hills.
Suggestion #1: Using equal amounts of Dawn Dish detergent and Pine Sol, use a spray bottle hooked to your hose and spray your yard, cracks, along the side of the house. This mixture takes care of fleas, beetles and destroys ant hills. It also makes your grass greener and is safe on your flowers and plants.

*DO NOT put Pine-sol on your animal to take care of fleas! There are dangerous chemicals in Pine-sol that could harm your animals health.

Suggestion #2: Stir 1 gallon white vinegar, 1 pound of salt, and a generous amount of lemon dish detergent mixed with a watering can, sprinkle this mixture on the unwanted weeds. The weeds will be dead by morning and the mixture does not hurt animals.
Suggestion #3: Pour white vinegar directly out of the bottle on the weeds. The weeds will be dead in the morning. You could even put the vinegar in a spray bottle and use. It also works good on cracks in the driveway.

Natural Organic Weed Control

The natural way to control weeds is to build the soil by increasing the organic matter and most weeds won’t be a problem. In the interim, hand pull problem weeds, spot spray with vinegar-based herbicides and apply corn gluten meal at 20 lbs./1,000 sq. feet spring and fall prior to seed germination.

For winter weeds spray between Christmas and New Years with vinegar. The best mixture is full strength 10% pickling vinegar into which is mixed 2 oz orange oil and 1 teaspoon liquid soap per gallon of vinegar. This technique works fairly well any time during the winter when the summer grasses are dormant.
Weeds in Paved Areas

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.

Weeds in Beds

Weeds in beds can be killed by removing the tops one last time and then covering the problem area with 1/2' of compost followed about 5 layers of newspaper. Wet it all down and cover the paper with 2-4" of shredded mulch. Spot spray any weeds that manage to come through with the vinegar herbicide.
