I am looking for input and information on the Stratification of Strawberry seeds (Sweet Charlie's to be exact)
the directions that came with them in the cellophane bag from rngardens @ Amazon simply told how to do everything but the final step ... do you ZIP UP the bag after completing the necessary steps .. or simply put into the refrigerator for the 4 - 6 weeks with the bag open or slightly open?
I would think you zip it up to retain the moisture .. but on the other hand I am afraid it will mold if all the moisture is sealed in and no air gets to it for that long a period.
Yes, zip it up. The baggie actually does allow some oxygen through so the seeds don't suffocate. I've left things in the fridge for up to a couple of months, no problem.
My new trick this year is to soak the seeds in hand hot water for 24 hours, then freeze them for 24 hours in a dampened paper towel in the baggie. Lupines started sprouting in just a few days at room temp, instead of 6 weeks in the fridge.
I thnk so, for me that's what has worked, I've been very successful. But come over to the seed starting thread and ask there. WWKathy never stratifies, and she gets great results. I think she keeps her house pretty cool, that may be a factor. I don't know if she does Lupines, though.
The Strawberry Seed Store recommends freezing strawberry seeds (achenes)
for 3 or 4 weeks to condition them for germination. Placing them in a freezer as soon as they come will have them ready for spring.
