Why Hydrogen Peroxide Is An Effective Treatment for Plants

Gardening with hydrogen peroxide may sound odd, but it’s actually a well-known pesticide treatment for organics farmers that can also be used safely for your garden. With the controversy surrounding toxic pesticides and small children, you want to ensure you choose a safe, but natural method for killing those extra pests in your garden who may wish to eat your fruits, vegetables, and flowers, before you have a chance to enjoy them too.

Using hydrogen peroxide is not only inexpensive, but easy to use to treat plants before your garden is overrun with tiny insects or root rot.

Why Is Hydrogen Peroxide the Best Treatment for Plants?

There are many benefits of using hydrogen peroxide rather than an expensive pesticide from your home and garden shop. It’s a replacement for pesticide that is used to kill bugs that want to eat up your garden. It’s recognized by the USA EPA, so you know that you’re using a tested gardening method.

Pests can get into your garden before you even see them. While many gardeners practice the physical removal of bugs to keep their plants safe, often they can move in before you even see them.

how hydrogen peroxide kill pestsHydrogen peroxide is sprayed or poured onto your plants as a diluted solution. It will kill pests from the root up, and throughout the soil. It actually only takes a small amount. While HP is safe for use around humans, pets, and small children, it can burn through the thin tissues of bugs. These may include fungus gnat larvae, cutworms, and other parasitic nematodes. It can also control populations of aphids and spider mites which also love devouring your plants.

How Exactly Does Hydrogen Peroxide Kill Pests?

Hydrogen peroxide works better than simply pouring water on the soil or your plants. The hydrogen peroxide actually creates a chemical reaction as it breaks down. If you’ve ever rubbed some on a cut, you’ll have noticed how it foams and bubbles. Humans have been using it for many years as a natural skin antiseptic. It helps to increase the natural healing of cuts, and prevents skin infections from setting in—often caused by fungus, bacteria, or viruses.


When hydrogen peroxide is poured onto soil, it will naturally form water and oxygen. This reaction is called oxidization and is harmful to bugs, as well as viruses, fungi, and bacteria that may be lingering on human skin.

It works well as a preventative as it’s harder to kill larger pests in the garden. But the sooner you can get the process going, you’ll begin to realize that your garden will have fewer pests, and your plants, fruit, flowers, and vegetables will all grow more fuller leaves, and with full crops.

Hydrogen peroxide works the same way as store-bought pesticides, but is a much safer way to do so.

Other Benefits of Hydrogen Peroxide for Plants

There are some other benefits to using hydrogen peroxide for plants. It can be an effective way to allow for soil aeration and to lessen the effects of root rot. Sometimes root rot can quickly take hold. The hydrogen peroxide will boost levels of oxygen in the soil, which is needed to combat the root rot. It will also kill anything in the soil that may be causing the root rot to take hold.

Hydrogen peroxide is also an effective way to provide water treatment to your plants. Many cities and towns don’t have great water. It can be full of chlorine, bacteria, and metals. Mixing hydrogen peroxide in your water can improve your water before watering your plants, and is a great method to remove these harmful compounds from water used to water plants. It does this through its powerful oxidation process.
