If your garden is looking less than stellar then hydrogen peroxide might just be what you need. Hydrogen peroxide for plants is a friendly alternative to harmful chemicals.
Today, we’ll be discussing ways you can use this little gem for a more robust garden. Let’s get started!
What is Hydrogen Peroxide
Hydrogen peroxide is a colorless liquid that is similar to water but slightly more viscous. You can get a bottle of hydrogen peroxide anywhere from the grocery store to drug store.
It’s usually available from pharmacies at 3 and 6 percent concentrations. These are sometimes described in terms of the volume of oxygen gas generated; one milliliter of a 20-volume solution generates twenty milliliters of oxygen gas when completely decomposed.
It is used as an oxidizer, bleaching agent, and antiseptic.
However, it can be used not only for cleaning wounds but, it can also do wonders for your garden.
While it is not an organic product, it is still considered safe for use and environmentally-friendly.
This is because it ultimately decomposes into oxygen molecules and water so you don’t have to worry about using it in an organic garden.
It Combats Root Rot
Root rot is a common problem that is often caused by being too generous when watering your plants and poor drainage. When you over water your healthy plant, any pockets of air found in the soil are filled with tap water which basically drowns your garden plants at their healthy roots.
