There have been some really useful comments to you post above. I would add only this...
I have found that refridgerator storage *sometimes* gives that delayed response mentioned. However, short-term storage (a few days maybe a week) has given me excellent germination. For example, I live well away from my patches, I have the seed I buy delivered. To my home, Avery close to the time I am planning to plant, and then it goes into the ground. Like within a week of my getting it.
Well, I will also add that predation by the critters out there is a real problem. Voles chipmunks, and mice get the seed before it has had a chance to come up. Deer are like lawnmowers for our crop. Find a good tree to go up with your climbing stand near every patch you put in.... This is helpful.... Slay a few of them near your patches, and it will help.
Don't give up! Check every place you!ve planted next year, and you might be pleasantly surprised....
