I have weeds all over my property in Southern California in (approximately 3/4 acre) When I had a smaller property weed control was my hands and garden tools. My new property is so large the weeds are taking over. Have you tested various types of non-toxic weed control (like 20% vinegar/dish soap/salt) with the results? It would be extremely appreciated to have a list of tried and true/fail experiments, so I could get my property under control. Sincerely, Dawn Nichols

I may help to identify the specific weeds that you are trying to eradicate in your garden.
I would encourage you to contact your local County Extension Office to inquire on weed control of weeds specific to your area.

Here are some additional links with more information on natural weed control.
Check out using corn meal. It works as a pre emergent herbicide and is non toxic. It shouldn't harm existing plants, but will reduce the number of weed seeds that germinate. I think there is a commercial pre emergent herbicide that is corn meal based for large areas, but I don't know if it has other components.
