Recently there has been a series of lawsuits involving Round Up Weed Killer concerning cancer. The solution to weeds and the protection of yourself, pets, and the micro environment of your yard is white vinegar. Round Up has been suspected and accused of being a cancer causing agent for years. This was partly the reason Monsanto sold Round Up to Bayer a year or so ago.
White vinegar has an amazing amount of usages and your yard may be one of the best usages of all. White vinegar is a wonderful cleaning agent as many people know but it also is a safe fantastic weed killer. On top of this it is very inexpensive to boot. Recently I purchased 2 gallons of white vinegar at Costco for $3.26. Compare that to 1.33 gallons of Round Up at $24.97 at Home Depot. The cancer is the no brainer part.
Following is a link to 70 plus usages for white vinegar and I personally utilize white vinegar as cleaning agents for things such as the dishwasher, coffee makers, surfaces, and mirrors to name a few. I cook extensively with several kinds of vinegar as well and the weeds in my yard are controlled by white vinegar. Needless to say white vinegar is a very versatile product in , and outside, my home.
