I did lol. I did a 4:1 ratio with water and hydrogen peroxide H2o2. I did this to help with some aphid larvae. I read that’s what people do. Also read that some people do this to help flush a plant and clean up root issue. But I do t know. Lol. From what I seen with the Hydrogen peroxide it did not hurt my plants and may of helped with the aphids. I’ve now switched to botanigard 22 for the aphid problem

problem is, in soil, the bacteria breaks down minerals so that they're available to the plant. That peroxide just killed them. Lol

Or at least that's what I thought. I'm baked though. Could've been in a dream I had. Lol

Depends on how deep the pot is, and how much organic matter it came in contact with in the first couple of cm. It could have all oxidized off in the first layer, in which case it would just be water.
The microbes would recolonize the top layer pretty quickly from below.
Still, the others are right, there are better things to use in soil.

Clears off any molds or fungi on them. It's a good idea to use it on them before any longer term storage.

There are a lot of questions about H2O2 with few good answers.
I would like to spray my leaves of my outdoor plants after a wet two weeks of wet and damp weather. This would be preventative because I had some PM last year.
The problem is that a lot of places say something like "solutions of hydrogen peroxide (9 parts water to 1 part hydrogen peroxide)."
BUT - they do not say what the starting concentration is for the H2O2. I might assume starting with a 3% solution taking it down to a 0.3% solution to spray on leaves.
For leaves, some places say
A. "one cup 3% hydrogen peroxide per gallon of water."
B. "1 tablespoon of hydrogen peroxide for every 1 cup of water "
C. "1 teaspoon of 3 percent hydrogen peroxide to every 1 cup of water. "
For roots
D. "1 pint of 3 peroxide hydrogen peroxide for every 1 gallon of water"
Standardizing units
One US gallon = 3.8 litres
One Pint = 0.47 litres
One Cup = 0.23 litres
One Tablespoon = 0.015 litres
One Teaspoon = 0.005 litres
A. = 0.23 / 3.8 = 0.0018 %
B. = 0.15 / 0.23 = 0.02 %
C. = 0.005 / 0.23 = 0.00065 %
D. = 0.47 / 3.8 = 0.124%
Have I made any mistakes?
Note for the Americans: The USA is officially a metric country but no one cares to use metric.
This place says it is OK to use a 3% solution to spray leaves
use hydrogen peroxide as an insecticide or insect repellent, make a 1% dilution.

Why is there no stadard advice such as
Leaf spray = 0.3%
Root watering = 0.1 %
- or something like that?

This is simple stuff - Such info should already exist because it is applicable to many plant applications.

Some guy on 420magazine forums says he uses
Insecticide Spray: combine 250ml 3% H2O2 to 1 gallon (3.8L) spray mix = 0.066 %
Elsewhere it says "a 1% hydrogen peroxide solution will help to repel insects"

As a Foliar Spray
This preparation is ideal if you’re dealing with fungi, bacteria, and pests. As a general rule of thumb, add one tablespoon of 3% hydrogen peroxide per eight oz (one cup) of distilled water (0.065%). Alternatively, you can combine one cup of the chemical with a gallon of water (0.061%).
