Stratify Seeds

New seeds came today from a mail order company. The instructions say to stratify them for x# days. The Internet leads me to various sites and blogs with different methods to stratify. The seeds requiring this technique include riverbank grape seeds, raspberry seeds, blueberry seeds, and pawpaw seeds.

Does anyone have a favorite and proven method? Do the different types of seeds require diverse methods?

Stratifying seeds is often different for different seeds and differing sized seeds so I'd tend to use a search engine and ask it about each type of seed you have .
Ie ask " Stratifying Rasberry seeds " or " Rasberry seed + stratification " etc. etc.

Some are just covering seeds in damp sand and leaving on a cold wall out of the sun for " X " weeks etc , others ask for use of a refridgerator , others ask for wetting seeds , rubbing off bits of casings and others simply just covering with a damp cloth for a few days at nigh on room temperature.

Last year I ordered Sea Kale seeds from Nichols Garden Nursery. Funny things...each seed appeared to be encased in a cork-like substance (I guess to assure the sea kale's seeds float on the ocean currents to wash up on new beaches before sprouting). Anyway, I found it easy to file a notch in each seed with an old nail file. I now have four sea kale plants which have gone into 'hibernation' for the winter. I'm looking forward to seeing them emerge next spring...one of which I will cover with a pot to blanch so we can cook it in the European manner.
