Pesticides and herbicides, or weed killers, often contain harsh chemicals. The cost of purchasing commercial weed killers can become a large expense over time. Learning how to make homemade weed killer helps lawns and gardens thrive without spending a fortune on chemicals.

Most homemade weed killers are non-selective, meaning the weed-killing solution also kills beneficial and desirable plants. Apply weed killers carefully, so liquids or powders only touch the weeds. Fortunately, homemade weed killers do not saturate soil or plant roots. The ingredients do not hang around long after application.


1. Vinegar in Homemade Weed Killers

Many popular homemade week-killers contain distilled or apple cider vinegar. Most vinegar contains a 5% concentration of acetic acid. It kills weeds because acetic acid is a desiccant that removes moisture from plants.

Horticultural vinegar contains 20% acetic acid. It is a much stronger weed killer than household vinegar, but it is also much more corrosive. Use caution with horticultural vinegar and wear goggles and protective clothing while applying it.
