1. Are organic weed killers completely safe and free of toxic elements?

Most organic weed killers are considered environmentally safe when used as directed. Always pay attention to the warnings: Just because a product is natural or organic doesn't mean it won't emit fumes that can cause headaches or other unpleasant side effects.

2. Is it true that organic weed killers will harm my soil?

It's possible, especially if the product contains salt, which can last for years in the soil before washing away. Natural herbicides containing vinegar or other non chemical ingredients are less likely to last more than a few days in the soil.

3. How often can I use organic weed killers?

That is determined by the product. Most sprays can be used as soon as new weeds appear, though some may require two or more applications to completely eliminate certain types.


Organic weed killer has become a popular alternative to commercially available chemical weed killers. The Doctor Kirchner Natural Weed & Grass Killer is our top pick for those looking to kill weeds without causing harm to the environment.
