Hi all just wondering with some advice on stratifing zelkova,is it best to seal in a bag and put in fridge, or put in seed raising mix and refridgerate? And for how long ?

Either will work Dave as long as the seeds are moist. It is usual to mix seed with damp sand, peat, sawdust, etc when you put them in a bag to stratify. You obviously do not have a Fridge Nazi at your place. A seed tray with seed raising mix would not last very long in the fridge here!
Times of 6-8 weeks are usually recommended for stratification. I was going to say until the end of winter but note where you come from so that will not mean anything to you.

Thank you for the information, we don't have much of a winter up here.
Don't know bout the fridge yet, cross that bridge later LOL
