i have a bunch of seeds that i have kept in my fridge now some for 2 years. will that stratify them, or do they need to get wet, and cold to stratify them?

got some trident seeds i'd like to sprout.

shaggybirdman

to stratifying trident seeds will just being in the frig do the trick, or do they really need to go threw a winter? these seeds have been in the fridge for almost 2 years. do ya think they will still sprout?

hmmm guess i should just give it a try, and see what happens.

In the fridge wrapped in a moist kitchen towel and inside a sandwich bag is normally all that is needed, and it is normally 2-3 months, not years lol,

You could always try them, if they work, you have some more trees, if they fail you have some compost to stick back in the heap.

I merged your two threads, seeing as they were on the same subject, to reduce any confusion / repeated information sharing.

lol no i wasn't stratifying them, but just storing them. i'll give that a try, and see/report what happens. got the seed from Ryan back in the day.

If they were kept dry in fridge, no chemical reaction could occur thus breaking the dormancy.

You should wet them in a paper towel, in a plastic bags for 90-120 days.

Check on them once a week, as some may germinate earlier. These one should be planted as soon as possible.

Check on them to make sure they are not rotting in your fridge.

shaggybirdman

i'll check on them today. after wetting them put them back in the fridge?

Yes, soak them for 24-48hrs. Usually, viable seeds will drown. Floater are usually empty or the water as not penetrate to the embryo.

I have read that maple seeds need to go through two winters to germinate. I have some seeds of acer grandidentatum var. sinuosum that I am currently stratifying; I have them in a tray of moist potting soil, covered to keep in the humidity (I probably should have done the paper towel thing). They have already received two months of cold stratification followed by two months of warm stratification, and they are now in the second phase of cold stratification. I have also read that they need light to germinate. This is my first time trying this; so we shall see what happens.

Hope your endeavors are succesful!
