Cinnamon oil is an effective yet cheap way to get rid of aphids. Most chemical pesticides are not only heavy on the pocket, but they are also harmful. 

Cinnamon oil, while being safe, is quite powerful, which is why you need to dilute it before using it. When you dilute the cinnamon oil, it will release its actual smell, which is how it will keep aphids away. 

How To Use Cinnamon Oil on Plants

Before using cinnamon oil, it would help to hose down the aphids with a strong spray of water. When you spray the plants with water, most of the aphids will fall, and you will have less of them to deal with it.

Make sure you wash underneath the leaves of the plants because aphids tend to hide under them. 

Next, you should dilute the cinnamon oil until it is 1% in water. It would be best to put the cinnamon oil mix in a pump sprayer.

If you use a pump sprayer, you can easily reach all the corners of the plant and get an even spray.

It is important to remember to only use 1% cinnamon oil with 99% water. If you use more than 1% cinnamon oil, there are chances of it burning your plants.

Also, when you begin spraying the plant, it is important to spray evenly instead of concentrating on one place. If you spray your plants evenly, in a consistent manner, you will have a better chance of getting all the aphids – hence the need for the spray bottle. 

It would help if you also resorted not only to leaves but also to the bottom and stems of the plants. The stems of the plants are where the aphids lay eggs.

It would help if you also sprayed on the ground where the aphids fall. After a few hours of spraying cinnamon oil, the aphids will die.

It is essential that you continue to spray every two weeks or if you spot any aphids. While cinnamon oil is not harmful as chemicals, it is quite strong, which is why you should refrain from spraying too often. Therefore, you should spray cinnamon oil evenly and avoid focusing on one area.
