How to Make a Weed Killer Using Orange Oil, Vinegar and Dishwashing Detergent


Organic gardeners frequently seek out new recipes for herbicides. Whether they are infesting a vegetable or flower garden, weeds compete with the plants for moisture and nutrients in the soil. One of the active ingredients contained in household vinegar, acetic acid, is a natural desiccant that will dry the moisture in foliage. It is not, however, particular about which foliage it acts upon, so it is important to focus the spray of the homemade herbicide only on weeds, and not desirable vegetation.

Step 1

Combine 1 1/2 tsp. dishwashing detergent, 1 tsp. orange oil and 4 cups vinegar in a spray bottle.

Step 2

Spray each weed until it is drenched with the herbicide.

Step 3

Withhold watering for one day.

Step 4

Repeat the procedure if new growth appears.
