You might be wondering why you should trust our 35 food-grade hydrogen peroxide over the small, simple bottles you can get in the supermarket. The hydrogen peroxide you can pick up at the pharmacy is typically 3% grade, excellent as a disinfectant but not safe to ingest. Our 35 food-grade hydrogen peroxide is the same stuff they use in food production. While proper dilution is important, food-grade hydrogen peroxide is much safer for ingestion and is therefore much better to use in the garden. 35% hydrogen peroxide is often what is used in vegetable washes and can be used as a preservative. It is often much more versatile in what it can be used for and that makes it perfect for plant use.

Hydrogen peroxide can work very well as a preventative measure against multiple types of fungal and bacterial diseases. It also works very well to kill and prevent crabgrass from growing on your lawn. It can be an excellent pest control or an infection preventative. It also works well to treat tree rot. It can be used as a general fertilizer, either added to water or sprayed directly onto the foliage. Why can it be used in so many ways? Why is hydrogen peroxide so good for plants?

How To Use 35 Food Grade Hydrogen Peroxide on Plants 

Proper dilution is important when treating plants with 35 food-grade hydrogen peroxide. When using to water or mist plants directly or to soak seeds, make sure to add only seven to ten drops per cup of water. When using to treat sick or fungal infected plants, make sure to add only one-quarter of a teaspoon per cup of water. Keep in mind that a concentration of 10% is usually recommended as a weed killer—because it will kill plants at that grade. When in doubt, make sure to add more water and less hydrogen peroxide.

Precautions to Take 

35 food-grade hydrogen peroxide can burn plants. It can also irritate the skin, so it is important to wear rubber gloves when handling it. Always make sure the hydrogen peroxide is properly diluted before applying it to the plants. It is a good idea to test the solution before using it in excess. Try spraying a small section of a leaf and leaving it overnight. If the leaf appears undamaged, the solution is properly diluted and can be used all over the plant. If there is any sign of damage or burns, remix the solution and start over. Hydrogen peroxide is an environmentally friendly alternative to most pesticides but it must be used properly.
