It’s a question that plagues many green thumbs-in-training: can I spray vinegar on houseplants? The short answer is it depends on the type of plants, but there are a few things you should know before getting started.
Though there are many opinions out there, it is important to consider the science behind using vinegar on plants before making a decision. This blog post will explore the effects of household vinegar on different types of houseplants so that you can make an informed decision for your plants.
Which Plants Benefit Most From Vinegar?
Apple Cider vinegar, white vinegar, and even balsamic vinegar can be used for your plants! There are many benefits to using vinegar in the garden. It is an acidic solution that can help to lower the pH of your plant’s soil. This can be beneficial for plants that prefer acidic conditions, such as rhododendrons, azaleas, and gardenias.
Vinegar can also help to control fungal growth and deter pests like mealybugs and aphids. When used in moderation, vinegar is a safe and effective way to care for your plants.

Acid-Loving Plants
One type of plant that benefits from vinegar is an acid-loving plant. These plants typically prefer soil with a lower pH, and adding vinegar to the soil can help to lower the pH and make the soil more acidic.
Camellias, azaleas, Japanese anemones, gardenias, and some fruit plants are all examples of acid-loving plants that will thrive with a little bit of vinegar added to their soil.
Vinegar is beneficial for these plants because they prefer slightly acidic conditions. In addition, vinegared water can help to prevent fungal diseases like powdery mildew.
To use vinegar in your gardening, simply mix one part vinegar with ten parts water. Then, transfer the mixture to a spray bottle and apply it to the leaves of your camellias (or other acid-loving plants). Be sure to avoid spraying the flowers, as the vinegar solution could damage them.
Use Of Vinegar As A Fertilizer
In addition to being used to change the pH of the soil, vinegar can also be used as a fertilizer for certain plants. The acetic acid in vinegar is plant food! When you add vinegar to the soil around your plants, it provides them with a boost of nutrients that helps them to grow bigger and stronger.
Use Of Vinegar As A Pesticide
Vinegar can also be used as a pesticide. The acetic acid in the vinegar will kill pests such as aphids, mites, and scale insects. Add 1 cup of vinegar to 1 gallon of water and use it to spray your plants.

Use Of Vinegar As A Weed Killer
Vinegar can be used as a weed killer. The acetic acid in the vinegar will kill weeds. Add 1 cup of vinegar to 1 gallon of water and use it to spray the weeds around your plants. Be careful not to get any on your plants!
Of course, you don’t want to pour straight vinegar onto your plants. Vinegar is an acid, after all, and too much acid can damage your plants. Instead, mix one part vinegar with ten parts water, and use this mixture to water your plants once every two weeks or so. This will give them the nutrients they need without harming them.
Remove Residue From Pots And Planters
If you notice that there’s a build-up of residue on your pots and planters, don’t worry – vinegar can help with that too! Add equal parts water and vinegar to a bowl and use a sponge to scrub away the residue. The acidity in the vinegar will break down the residue without damaging your pots or planters.
Get Rid Of The Fungus
The fungus can be difficult to get rid of, but luckily, vinegar can help with that too! Soak a cotton ball in white vinegar and apply it directly to the fungus. Leave it on for 24 hours before washing it off with warm water.
Repeat this process until the fungus is gone completely. You can also add1 a cup of white vinegar to a gallon of water and use it to water your plants once a week – this will help prevent fungus from growing in the first place!

The Negative Effects Of Vinegar On Houseplants
Though vinegar can be helpful for some plants it can have negative effects on certain types of plants.
Herbaceous Plants
Herbaceous plants are those that have soft stems and leaves. They are usually annual plants or perennials. Vinegar can damage the cells of herbaceous plants, which will cause the leaves to wilt and the plant to die.
Perennial Herbaceous Plants
Perennial herbaceous plants are similar to herbaceous plants, but they live for more than two years. Vinegar will have the same effect on perennial herbaceous plants as it does on regular herbaceous plants – the cells will be damaged and the plant will eventually die.
Perennial Woody Plants
Perennial woody plants are those that have hard stems and woody roots. They can live for several years. Vinegar will not damage the cells of these types of plants, but it can stunt their growth if used in high concentrations.
These types of plants are typically found in gardens or as houseplants. If you have any of these plants in your home, it’s best to avoid using vinegar on them or near them. Some examples of specific plants that could be harmed by vinegar include roses, azaleas, rhododendrons, and gardenias.

What To Do If Indoor Plants Are Affected By Vinegar?
As an indoor plant parent, you know that sometimes accidents happen. Maybe you accidentally spray vinegar or used too much vinegar while cleaning your plants’ leaves, or perhaps your pet knocked over a bottle of diluted vinegar solution.
Whatever the case may be, if your indoor plants have been affected by vinegar, don’t worry—there’s a fix for that. Here’s what to do:
- First, rinse the affected area with clean water. This will help to remove any residual vinegar solution and dilute the acidity of the vinegar that has been absorbed by the plant.
- Next, increase the frequency of your plant’s watering schedule until you see new growth. This will help to flush out the roots and remove any leftover vinegar solution. Adding some extra humidity to the air around your plant can also be helpful.
- Move your plant to a shady area and refrain from fertilizing for a few weeks. This will give your plant time to recover from the shock of being sprayed with vinegar.
- Finally, give your plant some extra TLC until it has fully recovered. This means fertilizing regularly and making sure to keep an eye out for any pests or diseases that may take advantage of a weakened plant.

Conclusion
Vinegar can be an effective weapon against many common houseplant pests. It is important to remember, however, that vinegar is also a strong acid and should be used with care.
Be sure to test any solution on a small area of the plant before treating the entire plant, and always err on the side of diluting the vinegar more rather than less. With these precautions in mind, you can confidently use vinegar to keep your houseplants healthy and pest-free.
