6 Great And Unusual Uses Of Hydrogen Peroxide In The Garden

Hydrogen peroxide is a must in the bathroom to disinfect wounds, whiten teeth and lighten or bleach hair. Connoisseurs also know how to use this bactericidal stain remover as a replacement for the usual household products to clean all surfaces or to bleach white linen better than bleach and to remove stains better than black soap or white vinegar if it is associated with baking soda and washing-up liquid.

In short, there is no shortage of everyday uses for those who know how to use it. However, it is generally less known that this colorless disinfectant product from the drugstore or supermarket also has some unusual uses for gardeners!

Also known as hydrogen peroxide, hydrogen peroxide has bactericidal and oxygenating properties. Thus, it can stimulate the development of the root system of seedlings or the growth of seeds as well as prevent plant diseases or the appearance of harmful pests, molds or algae. In addition to being a good alternative to chemical pesticides that poison the soil, it also acts as a fertilizer and will naturally oxygenate the plants. When used properly, this multi-purpose water solution can be very useful for the gardener. Get your gloves (to avoid possible irritation from this miracle product) and start gardening!

And precisely, what are the uses of hydrogen peroxide in the garden?

1) It will accelerate the germination of your seeds

In fact, it will allow to soften the film which is around the seed, which will stimulate the germination. Moreover, it makes it possible to remove the bacteria on this same film. Thus, the future plants are preserved from possible diseases which can affect their growth! To do this, simply soak the seeds for 30 minutes in 10 parts hydrogen peroxide. Then proceed to plant the seedlings as usual.

2) Hydrogen peroxide takes care of the roots of garden plants

Unfortunately, we often tend to overwater plants. This has the effect of rotting the roots and the plant then tends to quickly wither away if you do nothing. This is because the water fills all the empty spaces, which has the effect of suffocating the plant. When a plant has been overwatered, use a solution of 3 ml of hydrogen peroxide per liter of water for watering. This will give the plants an oxygen boost. Then limit watering until the soil dries.

3) It is also an unknown insecticide

Like a chemical pesticide, 10-volume hydrogen peroxide will help fight harmful pests. It can also be used against cabbage worms or to kill bacteria on fruits and vegetables. To do this, you need to mix it with an equal amount of water and spray it on your plants, fruits and vegetables. This will keep insects away and prevent them from laying their eggs.

4) Hydrogen peroxide can fight mildew and mold in the garden

This trick is already known by horticulturists and rose growers to stop the proliferation of fungi. It is both a preventive remedy and a very effective treatment if the infestation is proven. To use it, you will just have to incorporate 10 tablespoons of hydrogen peroxide 10 volumes in 1 liter of water. Then, spray this product until the mold disappears.

5) It can be used as a natural fertilizer

From time to time, it is quite possible for you to stimulate the growth of your plants with a touch of hydrogen peroxide. It will naturally strengthen the roots and help them to better absorb nutrients from the soil. How to proceed and in what doses? Mix 1 teaspoon of hydrogen peroxide in about 4 liters of water.

6) And finally, hydrogen peroxide takes care of the water in garden ponds

Fountains and ponds are a popular cool spot in the garden. However, they need to be well maintained to remove algae and pathogenic bacteria that grow in them. To purify your water, simply add 250 ml of hydrogen peroxide per 30 liters of water! No more need for chemical products for disinfection and water treatment.

It would have been a shame to limit this product to teeth whitening or blood stain removal!
