10 Best Essential Oils for Gardening

Essential oils are essentially (pun intended) the essence of plants. You can extract a plant’s natural oils from its flowers, leaves, stem, and even bark. These oils contain the constituents and components that make up a plant, which all have their own benefits and uses. As plants need to have a way to protect themselves from insects and disease, many essential oil components have insecticidal and antifungal properties.

Our list of the best essential oils for gardening contains oils that can naturally help to protect your garden, keeping it pest-free and healthy!

What Are the Benefits of Essential Oils for Plants?

This is best explained by describing what an essential oil actually is. 

Imagine that a plant grows in the middle of a garden, and its roots anchor it to the spot. Regardless of wind or scorching sun, it cannot move. If it rains too much and floods away nutrients, it can’t go to look for any others. Some plants are self-pollinating, but not all, so insects are essentially the genitals of the garden…but he can’t go on the pull. Neither when hoodlum caterpillars decide to munch him to death can he defend himself….

Or can he?

Actually, he can. He sends sweet fragrances into the air to seduce the insects. He changes his fluid intake to accommodate too much or too little water. He puts down chemicals into the ground to check no neighbors have any babies too close to him, and he sends up nasty chemicals to his leaves to either give the caterpillar belly ache or, if he is mean, ones that will make them sterile.

In short, those chemicals you use to make your skin soft are actually botanical warfare.

So, if your rosebush is covered in greenfly, she might be grateful for a blitz of clove oil, which killed 97% of aphids when tested in May 2020. What’s interesting, though, is that while aphids can be problematic, we don’t want to abolish the pollinators. We’ll leave that to the wretched chemical companies. Clove oil got rid of the aphids but selectively ignored the ladybugs. (Toledo, 2020)

    Essential Oil Sprays 

    One of the major benefits of using essential oils is that you don’t need to use very much of them! This makes it a very affordable way to create natural garden sprays. Use 15-20 drops of oil per full spray bottle for spraying weeds or around planters, while only 1-3 drops if spraying the plants themselves.

    Cotton Ball

    Cotton balls are a great way to deter larger garden critters such as mice and moles. To use this method, you must soak a cotton ball or pad with essential oil and leave it in rodent nests or burrows.

    Clean tools

    Each time you prune a rose bush or cut a stalk; your secateurs accrue mildew spores and pathogens. Give them quick oiling with tea tree before they go away to cleanse them and keep them moving.

    Gardeners Self Care

    Gardening can be hard work and brutal on your skin, especially your hands. Myrrh essential oil is wonderful for healing cuts and abrasions from even the wickedest rose bush.  Keep them soft and healthy with helichrysum essential oil.

    Can You Use Essential Oils on House Plants Too?

    Yes, absolutely. A personal favorite of ours is to use rosewater or an essential oil spray to mist the plants or polish off their leaves if they are dusty. The room smells fresh, and the plants seem to love it. 

    Does a Diffuser Work as a Humidifier for Plants?

    No. It does not correctly project the essential oils. Diffusers do not add huge amounts of humidity into the atmosphere. 


    When using essential oils for gardening, it is still important to take the necessary precautions:

      • Avoid direct skin contact with oils, as they can burn or otherwise irritate your skin due to their potency.
      • Be careful of pets and small children, as many oils (particularly tea tree) can be toxic.
      • If you are using these oils in and around your garden,  be sure that no one curious can get their hands or mouths on them!
      • Be very careful to wash any edible plants carefully before eating them.


    There are many ways to help control pests and diseases in the garden, but using essential oils is one of the most natural. As they come from the essence of plants, this makes great sense! Plants must protect themselves from these same threats, each containing components that will help.
