Need advice on how to sow old seeds

[Alexstudent]

 Hello. I am a beginner when it comes to palm trees. I have a problem that I need help with. I have bought many seeds of bungalow, and some other Australian palms from queensland 10-11 months ago. Haven't had the chance to sow them last year because I moved to another place. Now I finally have time to sow them. I kept them in the cellar with temperatures around 17 degrees. I have checked embryos on seeds, looks like they are still alive. I want to get as many sprouts as possible and wonder if there is any method that can stimulate old seeds to germinate? I have read that some people put old seeds in bleach solution to awaken embryos. Can you give me some advice? Thanks in advance.

I would just soak them in water.  The ones that sink to the bottom are probably still good.  But you can still plant the others.

Likely wayyy tooo long and they be no good now. 3-4 month max on most palms, often 3-4 weeks on some.

Maybe, but remember a date palm, "Methuselah" was sprouted by Dr Elaine Solowey, from a 2000 year old date seed. 😬

not true, mine dypsis seeds did germinate after 18 month 😃

You won't find out if they are viable until you try to germinate them. I don't know how long Archonotophoenix seeds stay viable but suggest you don't waste more time wondering what to do with them.

Archontophoenix has the reputation for a very short viability period,  and quick germination off the tree.
