For planted seedlings: Spray with H2O2 solution of 1 part H2O2 3% to 32 parts water (eg: around 30mls per 1 litre - measuring cup recommended). For established plants: Mix 1:1 ratio of 3% H2O2 and water (eg: 1 cup of each). Bottom or top water as usual (water soil only, do not pour on leaves).
Mix one pint of 3% hydrogen peroxide into a gallon of water. Water the entire plant, soaking the roots thoroughly, once every week. This oxygenates the root area, promoting development during any stage of the plant's life.
Use 1 ounce of 35% product per 11 ounces of water to make 3% hydrogen peroxide. 1 and ¼ cups of 35% H202 + 14 and ¾ cups of water = 1 gallon (16 cups) of 3% H202.
As an added bonus, hydrogen peroxide can help discourage unwanted bacteria/fungi that may be lurking in the garden. To give plants an added boost of oxygen or for pest control using the 3% solution, add 1 teaspoon (5 ml.) per cup (240 ml.) of water in a spray bottle and mist the plant.
It also breaks down into the soil and releases extra oxygen that helps the plant grow new, healthy roots. Before you use hydrogen peroxide on your plants, you'll need to dilute it. Mix one part of 3 percent hydrogen peroxide with two parts water in a watering can or spray bottle.
I would only use it as often as is necessary, but wouldn't recommend using it more than twice a week. What is this? If I'm treating a plant for pests or root rot, I'll either spray the leaves or the soil with a hydrogen peroxide solution once a week until the issue has been resolved.
It is perfectly safe for plants when properly diluted and used in moderation. Adding hydrogen peroxide to water promotes better growth in plants and boosts roots ability to absorb nutrients from the soil. Diluted 3% peroxide adds needed aeration to the soil of plants and helps control fungus in the soil.
Step 1: Mix one part of hydrogen peroxide and four parts of water in a spray bottle. Step 2: Lightly spray the plant leaves and stems where the adult fungus gnats are visible. Step 3: Repeat as needed until the adults are no longer visible.
Spray – 1 tablespoon of Hydrogen peroxide per gallon of water. Oil sprays, such as neem oil, fish oil, or sesame oil, also work on PM and other fungal diseases.
Hydrogen peroxide can help to control fungal growth and fungal infection, such as root rot, by preventing the growth of fungi. It can also help kill fungus and bacteria on plant roots.
Treat the soil.
Use 1-2 tablespoons of hydrogen peroxide per cup of water, and mix enough to saturate the entire root ball. Mix well, then apply to the soil. Hydrogen peroxide is root safe though it can look a little scary, because it will begin to bubble up when poured in. This is normal!
Combine a 4:1 ratio of water and Hydrogen Peroxide 3% – Oxygen Plus in a spray bottle (60ml of Hydrogen Peroxide to 300ml water). Increase to 2:1 ratio if your plant can handle it. Reduce the treatment to once a week until finished. Lightly spray the leaves to ward off unwanted pests.
The next time you get a beautiful bouquet of flowers, add a little bit of Hydrogen Peroxide 3% - Oxygen PlusTM to your vase water to keep foul odours away and help your flowers stay fresher longer. If your flower water has already developed an odour, there's no need to throw the flowers away!
Make an apple cider vinegar trap
Stir in a few drops of liquid dish soap and place the trap near the base of the affected plant or on top of the soil. You will need to refresh these traps every few days as they attract and kill the adult fungus gnats.
Hydrogen peroxide (H2O2) was initially recognized as a toxic reactive oxygen species, able to cause damage to a variety of cellular structures. However, it became clear in the last decade that H2O2 can also act as a potent signalling molecule, involved in a plethora of physiological functions.
Remove the affected roots, apply 3% hydrogen peroxide, and replant the houseplant in a new container with fresh soil. Disinfect soil before using it in your garden to eliminate harmful bacteria or fungus. Mix a tablespoon of hydrogen peroxide with eight ounces of water and sprinkle it onto the soil.
Don't just pour straight hydrogen peroxide on the roots. Instead, create a mixture of one part 3% hydrogen peroxide and two parts water, and put it in a watering can or spray bottle. You can either use it while the plant is still in the pot, or after taking it out of the pot.
Fortunately, you can get rid of these insects with a spray bottle and some hydrogen peroxide. Make a mixture of 1 tbsp (15mL) hydrogen peroxide mixed with a cup of water. Shake this diluted mixture thoroughly. Afterward, spray this on the leaves of your plants.
Hydrogen peroxide (H2O2) is steadily gaining more attention in the field of molecular biology research. It is a major REDOX (reduction–oxidation reaction) metabolite and at high concentrations induces oxidative damage to biomolecules, which can culminate in cell death.
Hydrogen peroxide kills root rot-causing bacteria and fungi and restores the oxygen balance in the soil which boosts your plants' growth and health. Due to its chemical similarity to water, hydrogen peroxide is one of the safest chemicals you can use in the garden to combat root rot.
To maximize the effects of hydrogen peroxide – and to use it safely – you must first dilute it. The familiar brown bottle found in stores contains 3% hydrogen peroxide, which is too strong for oral use. Dilute 3% hydrogen peroxide to 1% by mixing two parts water with one part hydrogen peroxide.
