Keep in mind essential oils are usually indiscriminate in what they kill, so take care to avoid and protect plants you don’t want to get rid of! Don’t spray when it is windy to avoid the oil mixture accidentally being carried on the breeze and try not to spray just before rain or the oils will not be as effective after being washed off.

How to Use Essential Oils on Plants

Unless using as a weed killer, it is important to use only a small amount of essential oils on plants and to make sure that they are diluted properly. A general rule of thumb is to mix 2-3 drops of oil per litre of water. You can also add the oil to a glass spray bottle and apply it directly to the leaves of the plant.

If you are using essential oils as a pest control, you should only apply the oil to the leaves of the plant rather than the roots.

If you intend to use the oils in a vegetable garden, make sure you don’t use any oils that could cause allergic reaction to anybody who may eat the veggies. Also bear in mind that some oils like peppermint can be toxic to animals so be sure to double check if an oil is safe for your furry friends before using in your garden.

It is also important to avoid getting any essential oils on the flowers or buds of plants. This can cause them to become damaged and may prevent them from blooming.

For outdoor plants you should check the weather conditions first and avoid application just before rain which will wash off the oils and reduce their effectiveness. For best results avoid application in direct sunlight as this can burn the plants and cause sensitivity. It is always best to water in the early morning or in the evening anyway to avoid any risk of the plants getting sunburn.

Are Essential Oils Safe for Plants - diffusing essential oils for indoor plants

If using essential oils as a weed killer, then a concentration of around 20 drops of oil per litre of water should be effective. Remember that high concentration oils will kill all plants, not just weeds, so take care to avoid spraying any area where you don’t want to harm the existing vegetation.

Diffusing essential oils into the air around indoor plants can be beneficial and is the best option for treating houseplants. This is a good way to protect them from pests and diseases and can also humidify the air around the plants. Adding a couple of drops of oil to your diffuser is the best way to treat house plants with fungal infections or insect infestations.

You can also add a few drops of essential oil to a cotton ball and place it in the pot with your plant. This will help to keep pests away and will also provide a source of nutrients for the plant.

Finally, always test a small area of the plant before applying essential oils to the entire plant. This will help to ensure that the plant will not be harmed by the oil.

The most important thing to remember when using essential oils on plants is to use them in moderation. A little bit of oil can go a long way, and too much can be harmful to both the plant and the person using it.

Conclusion

In conclusion, are essential oils safe for plants? It depends! Essential oils can be beneficial or harmful to plants depending on how they are used. Always do your research before using essential oils on your plants, and test a small area first to make sure they will not be harmed.
