I bought some Cornus urbiniana seeds (from USA) and the instructions that came with it says to sterilise the seed using "1 part household bleach diluted with 10 parts of water"
I'm not sure if UK bleach is going to be the same concentration as USA bleach?
I also have 35% Hydrogen Peroxide, which is what I normally used for sterilising things such as Colocasia bulbs to reduce chance of rotting when I start them off. If that would be suitable what dilution should I use please?
(I think the suggestion of sterilising may be related to the prolonged period of stratification which is needed?)
I didn't get the seeds from Strange Wonderful Things (I've never bid high enough to win any of their eBay auctions!!) but their site has details instructions and is very similar to the instructions I was sent:
