I use a bit every few waterings but I didn't know it could be used in these other ways as well. Just thought I'd share. 
Hydrogen Peroxide
Certainly hydrogen peroxide is handy in the home, from stopping tooth infections to wiping down surfaces, and 101 other uses.
In the garden, either as a general fertilizer, fungicide or weedkiller, H2O2 would be quite expensive, but you may be able to buy it more cheaply, or in bulk where you are.
A 3% concentrate solution is usually used for home or personal use, and the garden is the same. Higher concentrations can be dangerous and can burn skin and eyes. If you buy hydrogen peroxide at a stronger concentration such as 10% or more, remember to handle carefully when diluting with water before use.
Advocates of hydrogen peroxide for plant use, do so because it is a powerful oxidizer. As it combines with outside air and water it decomposes, freeing its oxygen elements. Thus it provides a supplement of oxygen to plants and aerates the soil.
Here are some ways to use Hydrogen Peroxide in the Garden
As a general fertilizer to enhance plant growth, use 1 teaspoon of 3% hydrogen peroxide to 1 cup of water or ½ cup h2o2 to 4 liters (1 gal).
Use as a foliar spray or soil soak to help produce strong, healthy roots.
Use to water newly sown seeds, or even to soak seeds in before planting.
Use this mixture when rooting cuttings, either in the water they soak in or in the soil they are in.
To deter and kill of mold, bacterial and fungal infections, double the above concentration at least, ie: 2-3 teaspoons per cup of water, or 1¼ cup per 4 litres (1 gal).
Spray on top and under leaves to combat blight, downy mildew and other fungal spores. Water in around plants to treat collar and root rot, and soil born pests.
To stop infections, paint or spray on pruning cuts. Dip secateurs in mixture to sterilize them.
To use as a weed killer, apply neat strength. If you can buy a stronger concentration than 3%, say 10%, this is more effective for killing weeds
