I just prune then I ram the cuttings in the ground they always seem to root.. that going to finding a pot thing smacks of effort 😆

If anything I think the peroxide would be more detrimental to them rooting than helping your going to be oxidising a load of microbes out of existence including the good ones. Its a bit like when people used to sterilise the soil years ago to remove pathogens they kill all the good guys and the bad guys usually end up establishing themselves faster.

Dunking them in some EM, or even just yeast and labs would be better. Or just push them into well cared for soil.
