Organic Herbicide for Grass

An herbicide may be a necessary element for maintaining a healthy green lawn. Chemical herbicides, however, may endanger the health of pets, people and the environment, so many gardeners choose organic an herbicide instead.

Considerations

• The health hazards of chemical herbicides are well-documented. The Connecticut Department of Public Health has published a fact sheet indicating that both short-term and long-term exposure to herbicides may lead to illnesses that range from nausea and skin rash to cancer and immunological disorders. Organic herbicides are much safer.

Organic Herbicide and Fertilizer

• Organic mulch works as an effective organic herbicide by blocking light to the weeds. In addition, the ingredients in organic mulch, which include bark, leaves, and grass clippings, help to enrich the soil as they break down and decompose.

Vinegar

• Vinegar is the most popular natural herbicide. Household vinegar, available in 5 percent strength, is effective on younger leaves, but higher concentrations are needed for older weeds. Garden centers and plant supply stores sell vinegar-based herbicides at a much higher strength.
