3% Hydrogen Peroxide Solution – Pest and Soil Treatment

Follow Amie Sue\\\\\\\\\\\\\\\

Hydrogen peroxide an environmentally friendly alternative to pesticides, fungicides, and chemical fertilizers. Always use hydrogen peroxide in a diluted form and handled it with care. My go-to’s with pest and fungus control is either a diluted rubbing alcohol solution or hydrogen peroxide, and a Neem oil solution. Anytime I witness a plant in distress, leaf changes, dropping leaves, etc. I pull out the artillery.  Today I will be going over my experience with peroxide.

I usually use it as a foliar (leaf) spray to control pests. I spray the top of the plant-soil and potting container to help with fungus and bacteria. I have even poured it through the potting soil to kill off any unusual microbial suspects like spider mites and fungal gnats. First and foremost, anytime you see pests on your plants, isolate them immediately, then proceed with the eradication process.

Golden Rules when Using Hydrogen Peroxide

Benefits of Diluted Hydrogen Peroxide

Foliage Infestation Pesticide Spray

Combine

Treatment

  1. Do a test area to make sure it doesn’t burn the leaves or delicate root system.  Spot spray an area and wait about three days before spraying the rest of the plant to see if there were any ill effects from the spray.
  2. If the spot-test looks good, proceed. Use a spray bottle to soak the infected plants thoroughly. Make sure to get the undersides of the leaves, top of the soil, and around the pot itself.
  3. Spray once a week or as you see bugs appear.
  4. The hydrogen peroxide will not kill eggs, so you may need to repeat the treatment weekly to remove all the bugs.
  5. Label the bottle and store it out of direct light.

Bacteria, Fungus & Infestation Treatment

Hydrogen peroxide helps to kill molds such as powdery mildew caused by any number of fungi. When applied to the plant, the chemical’s two oxygen atoms attach to the fungus and oxidize or burn it.

Soil Treatment for Pest Larva

Combine

Treatment

  1. Water infected plants thoroughly.
  2. The hydrogen peroxide will fizz as it comes in contact with the soil; that’s what kills the larvae and the eggs.
  3. Repeat in 2 weeks for a larger pot; in 7-10 days for a small pot.
  4. Label the bottle and store it out of direct light.

Grow Strong Roots

Hydrogen peroxide also helps aerate your soil, which should help to prevent future cases of root rot. When it is absorbed into the soil, the hydrogen peroxide breaks down and releases oxygen. These high oxygen levels will make sure your roots are healthy and strong. A healthy root system should be long and untangled with fuzzy white growth on the main root, which is used for soaking up water and nutrients. Here is a “recipe” to make up and keep on hand for future waterings.

Treatment

  2. Soak the area around the roots thoroughly.
  3. Label the bottle and store it out of direct light.
