Rosemary Essential Oil

This oil works amazingly well to help repel many pests in the garden and has a nice, woodsy fragrance. Even the larvae themselves have been demonstrated to be repellent.

To prevent insects from munching on your plants’ foliage, sprinkle a few drops of liquid directly on the pot. Butterfly attraction is another benefit of rosemary essential oil. They adore it, so having a butterfly garden can also be advantageous to you in this regard.

Peppermint Essential Oil

This oil has a sweeter smell and deters a variety of garden pests, including aphids, flies, beetles, and even spiders! To keep spiders out of your home, sprinkle peppermint oil along baseboards and inside of cabinets. I also use it to repel ants (adding more essential oils for pest control)!

Melaleuca Essential Oil

This oil works well for everything involving getting rid of fungus on your plants. You can use it to create a spray to sprinkle the soil and plants.

However, because it makes the plants more sun-sensitive, apply melaleuca essential oil to the stems rather than the leaves. Therefore, be warned that a thick application may result in leaf burn.

Lavender Essential Oil

Butterfly lovers also enjoy lavender’s aroma, so you may use it to your advantage by misting the plants with lavender oil. They’ll be even more intrigued by it!

Bees, which are crucial for pollination, are also drawn to lavender essential oil. To draw them in as well, put a drop or two on a cotton ball and lay it in pots or in the garden.

Orange Essential Oil

Bees and butterflies are attracted to orange oil because of its exceptionally fresh and pleasant scent. To assist attract them both, you can mix rosemary oil, lavender oil, and orange oil in a spray bottle or apply a few drops of each to cotton balls.

Cinnamon Essential Oil

One of the greatest essential oils for eliminating weeds is cinnamon oil. Get those weeds under control by filling a spray bottle with water and a few drops of cinnamon essential oil.

What kind of oil is suitable for indoor plants?

While repellents are quite effective against pests, occasionally they also hurt the plant. What are some natural oils that can be applied to houseplants, then?

Rosemary, lemongrass, peppermint, citrus oils, lavender, cedarwood, eucalyptus, and neem oil are a few of the oils that are advantageous and secure to use on indoor plants. A number of different oils also serve as organic pest deterrents and maintain the health and happiness of the plants.

Here is further information on the oils mentioned above, their uses, and their advantages for indoor plants. There is also information on other oils.

Which essential oils protect houseplants from pests?

Strong-smelling herbs can assist in getting rid of spider mites, aphids, and other pests from indoor plants. Use one or a combination of the fresh herbs basil, peppermint, lavender, sage, and rosemary. My favorite scent is a blend of rosemary and peppermint.

Which oil benefits plant leaves?

When applied to plants, vegetable oil has positive effects. It is an economical method of removing pests and cleaning plant leaves at the same time.

Vegetable oil is good for plants since it can protect them from pests and, when applied to leaves, makes them seem bright and clean. When not utilized properly, it can hurt the plants. Vegetable oil has been shown to be most beneficial when misted onto plants, making this method the most efficient.

You will have a solid understanding of how to use vegetable oil on plants, as fertilizer, and to ward off pests after reading this article.

Houseplants: Can essential oils harm them?

Although the idea of applying essential oils on plants might sound strange, it is actually extremely straightforward and has several advantages.

In addition to helping you get rid of pests from your plants, using essential oils on them can promote development and improve the natural appearance of any indoor gardens you may have. Some essential oils can damage plants if they are applied improperly or in high quantities.

Lavender oil: Is it harmful to plants?

Even while I adore our Lavender Luster, which purports to offer aromatherapy while you clean I never in a million years imagined seeing “aromatherapy while you weed! Some essential oils may be effective as a herbicide, according to Italian experts. They are discovering that plants’ root growth can be impacted by lavender essential oil. It also has an impact on the fungi and soil bacteria necessary for crop growth.

Can’t you just picture us spritzing the weeds while dancing around the fields? If only everything were that simple. It is clear that much research has to be done to determine what exactly happens to the weeds and whether the use of lavender essential oil harms beneficial bacteria. Cinnamon and peppermint essential oils are effective as pre-emergent herbicides that inhibit seed germination, according to research on other essential oils. Because they don’t linger in the environment, the essential oils utilized for this might be quite effective. They are quickly broken down by microbial and enzyme action.

This isn’t as unusual as I had believed, it seems. An herbicide from Monterey Organics has lemongrass oil as its active component. The Appalachian Fruit Research Station conducted a study in 2002 that discovered certain plant oils were helpful at eliminating a variety of weeds. Red thyme, summer savory, cinnamon, and clove were the herbs that were found to be the most productive. Even though there have been more studies and products developed, and I’m sure we’ll be testing some of them, I still adore the idea of people dressed in gossamer spritzing the fields.

Can essential oils be used to water plants?

My use of essential oils in the garden has increased as a result of this experience. I reasoned that tea tree oil (10 drops per gallon) should be able to help with blight and fungus/bacteria issues for the plants as well if it is so effective against fungus and bacteria. The use of thieves oil in the garden to prevent bacterial and fungal growth is also quite effective. Personally, I make my own blend of thieves oil because I find that purchasing the oil can be quite pricey. Another claim about oregano oil is that it works wonders against bacterial and fungal issues. Not only can cinnamon oil repel insects quite effectively, but it also possesses antibacterial and antifungal effects.

You may improve the culinary pairing of tomato and basil before the tomatoes even come off the vine by adding 6–8 drops of basil essential oil per gallon to your watering can. If you can your own tomato sauce, this will make your tomatoes wonderfully delicious. Other essential oils can be used to alter the flavor or scent of flowers, fruits, and vegetables.

You can simply add the essential oil to the watering can and spray the foliage as well as the area around the plant if you are aware of a companion plant for an ailing plant and you happen to have it on hand. Thyme and lavender are both excellent garden plant protectors for vegetables.

Do plants get harmed by peppermint oil?

Peppermint oil varies widely. Use only Mentha Piperita, is what I advise. I use this in my garden and sell it on my website. The perfume is the strongest, although it is a little more pricey. Make sure the label for the peppermint oil reads Mentha Piperita wherever you decide to purchase it. You want the most potent aroma. The recipe I use is listed at the conclusion of this post.

There are essentially two things that peppermint oil accomplishes to deter insects from entering your garden. It irritates you and covers the aromas of your veggie plants.

Very little insects like spider mites are effectively repelled by it. Some oil sprays are reported to suffocate and kill soft-bodied insects. That is accurate, but peppermint oil’s fragrance is what makes it popular. To create an insect smothering oil spray, much more oil would be required. For such use, cheaper unscented oils work better.

Insects use both sight and smell to find plants. Because of this, flowers are frequently colored and fragrant. Even if you use peppermint oil sprays, many of your pollinators will still be able to locate your garden with ease.

You break the plant when you harvest vegetables. When you choose a cucumber, tomato, or squash, you could detect three different smells. The odors are also detected by bothersome insects. The same scent or pheromones are released when pruning plants. Your peppermint spray assists in covering this up. Plant fragrances can also be released from damaged leaves caused by wind and severe rain.

Spraying on a schedule is essential for using peppermint oil effectively. I advise routinely spraying as a concealing smell every 5-7 days. You can spray the soil and the area around the plants. Spray a few leaves of each plant variety if you’re using the spray for the first time, then wait 48 hours to check for damage. When certain that your spray mixture won’t injure it, only completely cover a plant. This is a useful exercise before using any spray formulation on your garden.

Spray it every 3-5 days, being sure to penetrate under the leaves, if you are using it as a deterrent and irritant for tiny insects like spider mites.

First, It Is Important To Clean Leaves

To keep your plants clean, healthy, and working properly, it’s a good idea to sometimes wipe down their leaves. Indoor plants naturally accumulate dust, grime, and dander, which can obstruct the plant’s ability to absorb light. This has further effects on photosynthesis and growth of the plant. Cleaning the leaves with a natural, gentle spray might help remove particularly difficult filth while protecting the plant.

Cleaning the leaves of houseplants is also beneficial as a preventative measure to fend off potential pests and diseases before they become apparent. Damage is frequently more challenging to repair once it has been discovered. The aim is to catch problems early.

Why Manufactured Leaf Polish Isn’t Great

Most store-bought leaf polishes have the simple purpose of making the plant look better and shine more. Beautifying the foliage is encouraged on even the labels. Yes, cleaning the surface with a plant’s leaves generally works. However, the harsh oils and occasionally chemicals used to make these shines and sprays settle on the surface of the leaf. This may result in accumulation, clog the stomata (pores), and prevent respiration, which would hamper plant growth. Ultra-shiny leaves might look phony and be harmful. Who would want a fake plant when they paid for an actual one?

How To Make Your Own Houseplant Polish

Making your own DIY leaf spray at home gives you the chance to securely clean and enhance your plants. This concoction will remove and keep out pests, hard water stains, and dirt. Additionally, as the plant’s inherent beauty is shown, your leaves will acquire a faint sheen.


  • 2 glasses of water
  • a half-strength vinegar
  • 2 drops of castile or dish soap (Dr. Bronner’s is a favorite)
  • Coconut oil, two drops (optional: if you really want that glossy look)

After combining the ingredients, you can either use a spray bottle to apply it to the leaves or just dip a cloth into the mixture. Use a soft fabric, such as microfiber, to shield the leaves from harm in either case. Use a single disposable paper towel for every plant as an alternative to reduce the danger of possibly transferring pests or diseases between plants. (Alternatively, fully wash the cloth in hot water after each use.)

Although there isn’t a particular period of time, we advise cleaning your plants every month or so. Remember that this spray only works on specific types of foliage and shouldn’t be applied to very delicate leaves, such those with a fuzzy texture (like African Violets and Cacti). Overall, caring for your houseplants properly can promote growth, longevity, and survival. Happy cleaning of the plants!

Can I use peppermint oil through spray to my houseplants?

Most effective essential oils for houseplants Make sure to use peppermint oil that is 100 percent pure and derived from organic sources if you want to keep pests away from your houseplants. Place a cotton ball with one or two drops of the oil on it next to your plants or in an area where you frequently observe insects.

Can I use tea tree oil to spritz my plants?

Spray plants every three to seven days with a solution made of two cups of water and two tablespoons of tea tree oil to prevent fungal growth on plants and foliage. Spray early in the day and less frequently during hot, dry spells to prevent burning oil-treated leaves. Pull off the afflicted leaves and spray the entire plant if plants already have blight on the leaves but not the stems or fruit.

According to Green Harvest, tea tree oil also deters whiteflies, which produce a sticky honeydew that encourages the growth of sooty mold fungus on plants. Tea tree oil is typically safe for humans, however ingesting it can be dangerous. If you have allergies to balsam, benzoin, or plants in the myrtle family, it may also make you sick.

Turn On a Humidifier

My preferred way for increasing humidity for indoor plants is to use a humidifier because it is quick and effective. You can use a humidifier of any size, but if you have a large room with plenty of plants, you should use a larger humidifier, and vice versa.

Two of my preferred humidifiers are listed below:

  • If you have a large room, like a dedicated plant room, this humidifier from Air Innovations works great. Additionally, it lasts for 96 hours!
  • Essential Oil Diffuser by URPOWER
  • Yes, this diffuser for essential oils has been in my possession for a while. It performs equally effectively as a humidifier for small spaces. It fits comfortably on a shelf or table and lasts for more than six hours, which is why I like it.

Can you use an essential oil diffuser as a humidifier for plants?

In fact, you’ll discover that a lot of essential oil diffusers also have humidifier labels on them. However, in order for it to offer humidity, you’ll need to utilize it in a limited area or extremely close to your plant.

Make a Pebble Tray

A simple trick to make humidity last all day long is to use a pebble tray. The idea is straightforward: If you place a tray of water underneath your plant, the water will evaporate around it, generating humidity.

Although some humidity dissipates around your plant, I wouldn’t say this is THE MOST effective approach. However, I have tried it and found it to be helpful.

By placing your pebble tray and plant inside of something with sides, such as a fish tank, you can increase its effectiveness.

Pebble Tray Materials

  • As long as it is large enough, any common plant tray will work. In order for the water to evaporate around your plant, it must be broader than the pot’s diameter.
  • I also appreciate this bigger humidity tray a lot. It’s quite handy that there’s room for a few different plants. If you have numerous plants that require humidity, think about getting a larger tray.
