It all depends on what you're stratifying.
In general no two weeks is not enough. I assume you're wanting to know if you can strat the filiformis seeds for two weeks. You could but chances are you're going to get horrible germ intonation.
Two weeks is enough for some of the southern species like S. leucophylla, S. alata D. tracyi ect. but even then this is debated. The Carolinian species need at least 4 weeks. And then anything north of that can need anywhere from 6 weeks to 4 months of strat.

You can use GA3 and skip germination but stratifying for 6 weeks for sarr's works really well. For filiformis, just throw them on the medium and cover the growing area with snow for the whole winter.

GA3 and your wait shortens by about 4 weeks and 6 days

They're right, GA3 does shorten your time by JUST a little I'm old fashion and stick them in the fridge for strat. You wouldn't want to go much less then 5 weeks for S. purpurea ssp. purpurea. S. venosa or rosea can be shorter. On the GA3 note, do you guys have an effective way to treat a large volume of different seed? I just did about 50 different batches of seeds the normal way but I would love you hear if you have any tricks on this.

Never done any big batches, but I use coffee filter and drop them in the GA3 mix that way. Could maybe number them and have a code on a sheet of paper, then drop into a large bowl of the mix? Not sure if a little ink would hurt them or not.

If I could figure that one out it would save me a ton of time.

Could try using an empty tea bag or multiple small vials. I just got some Hal and I will need to figure how I am going to do this. I think I'll see if I can get some glassware from the chem labs at the Uni.

I live in a area where winters are strange and we have no way to tell when it is going to snow, other years we already have snow, being near the Atlantic ocean we get unpredictable weather, whats more is I expect 90 D Filiformis seeds I was wondering could I germinate them indoors, then once we get snow then put them outside and cover them in snow then, if not what do you suggest?

Sprinkle them over moist medium outside where it will be below 0C for the whole winter. Do not germinate them first. Put them in a protected spot, out of the wind and direct sun. Snow cover is good. An unheated shed or garage would be good.

There is a area between our shed and neighbors fence that is protected but still gets at least a foot of snow should I put something over the open top of the container or just bury it if I bury it, when the snow melts will it not wash away the seeds even if I leave a few inches from the top or will drainage take out the water without the seeds?? I tested my aquarium gravel/peat mix by pouring distilled water in it,the water immediately ran out the bottom in the tray, some got soaked in by the soil but most just ran out in the tray.[/i][/b][/b] Zero? if it goes bekow 0 say at night or stays cooler than Zero all day,even frost will the seeds be ok buried in snow? How about on a cold wall on concrete in a shed corner?

The protected area sounds good. If it's just seeds, I wouldn't bother burying it. I usually use undrained pots for outside stuff. Never had a problem with seeds washing out. Once the thaw comes just put it out in the sun. If there's going to be a really heavy rain, you might want to cover it until the seedlings are more established.

Concerning GA3, I've had a small bag for years. Tried many different concentrations (250ppm, 500, 1000) but is there any guidelines whatsoever for specific kinds of seeds, pertaining to the concentrations used, overall method and time of soaking?
What concentration you guys use?
Sorry to hijack your thread paulkoop, maybe this should be a new thread specifically for GA3... :S
