Hydrogen peroxide on seeds or seedlings
« on: Thursday, 18 October 2012 - 00:02:29 »
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.

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.

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

Hello,

Me & some of my other cactus colleagues from our CactusSociety use permanganate bath, its also very good for cleaning seeds.
