hydrogen peroxide / oxygenation
Particularly this wet year, I've been having a lot of trouble with wet
roots, bad root growth and shabby seedlings failing to thrive. I've started experimenting with hydrogen peroxide, bought from a "growshop" at 35% strength and used ~ 3 ml/12 l as per the instructions for oxygenation. Too early to tell if this is having an effect, but I was wondering if anyone else has used hydrogen peroxide for watering; it seems a standard technique in hydroponics anyway. Dull, wet and cold weather, ugh. -E -- Gardening in Lower Normandy |

Might be worth trying laundry bleach (sodium percarbonate) which is in powder form and only activates on contact with water. Easy to mix into the soil I would have thought |

You can certainly use it for sterilisation at higher concentrations, and indeed at 35% it's pretty powerful stuff. (I got some on my finger which turned completely white). But there is lots available about oxygenation of waterlogged roots on the net. Here's a study about avocado trees where this technique is explored: http://www.actahort.org/books/889/889_71.htm Here's a link on garden use in general, though I'm not sure the author is any kind of expert: http://www.using-hydrogen-peroxide.c...de-garden.html Might be worth trying laundry bleach (sodium percarbonate) which is in powder form and only activates on contact with water. Easy to mix into the soil I would have thought I would think laundry bleach would kill roots, not aerate them! But having looked it up I see sodium percarbonate turns into hydrogen peroxide and soda ash when mixed with water. So I guess this wouldn't be appropriate for my uses as it would make the water more alkaline, something I would avoid. Interesting idea though. -E -- Gardening in Lower Normandy |
