>Is there any point in using hydrogen peroxide (H2O2) when watering plants in soil that contains appreciable quantities of organics. I would have thought the oxygen would be soon mopped up, and not be available to plants, unless in large excess. Hydroponics growers use it with good results I believe http://quickgrow.com/gardening_articles/… the larger the concentration of organic compounds (Carbon containing, not chemical free!) the bigger the problem.
>Has anyone used H2O2 in watering to recover difficult bulbs, eg. Worsleya , from root rots?
