Hydrogen peroxide on seeds or seedlings

[andrea.a]

Hi,
I was thinking about how to clean new collected seeds from my plants, I do not like very much to bleach them (as many report), and I started thinking about H₂O₂ .

It could be a very easy and safe method, has someone already tried this substance?

It may be used also to prepare sowing substrates, clean seedlings and prevent fungal (or other) infections.

I read about using a solution obtained adding 1 to 4 spoons of hydrogen peroxide 3 % for gallon of water, it would be good for seedlings (but it was not an article about cactus or succulents). More concentrated solutions (up to 8 spoons for gallon) were suggested for adult plants desinfection.

Any experience to tell?

Bye, Andrea.

not such a great idea for soils. better put in the microwave the wet substrate.
it might be an idea for seeds!

Hi Andrea, I use it for many years to disinfect the seeds, use hydrogen peroxide 10%, diluted 1:2 with water. I know that is also used to remove the moss growing in pots planting. I have never tried this method and I can not tell if it works, I do with this problem suddenly the ground with a solution of cupric fungicidal and algae and mosses disappear soon.

Fanecchissimo and Karlet, thanks for your replies!
Unfortunately I have not a microwave   
I'll try to use hydrogen peroxide to clean seeds.
A question for Karlet: how long did you keep the seeds in cleaning solution? Have you observed something like scarification processes?

Andrea.

we use too peroxide to clean seeds, it works well.
About the microwaves, you can find some cheap ones for about 40 50 eur...

Hi Andrea, I keep the seeds in the solution for 20 minutes, shaking a couple of times. Not else scarification.
