Essential oils can naturally destroy weeds.
A study was done by the Appalachian Fruit Research
Station in West Virginia on the herbicidal effects of plant- derived oils (aka essential oils).
Twenty five oils were tested for their herbicidal effects on dandelion leaves. The most effective oils found were red thyme, summer savory, cinnamon and clove. These were found to be the most phytotoxic.
Cinnamon had the highest herbicidal activity. This was primarily because of eugenol, the main component in cinnamon.
Essential oils can be used directly on the weeds. Or they can be added to other natural products such as herbicidal soaps, to enhance their effects. These soaps work by penetrating the waxy coating on plant leaves and cause them to dry out.
