I find this most interesting PopsCoops, about planting in fall. I know from my experience with the family nursery I had for about 15 years, that many, many seeds had to be frozen for at least 48 hours. Things like snapdragons, in particular come to mind. The reason for this is that the freezing forces the dormancy of the seeds to break. I am pretty sure now that maybe many, many more than I ever understood about, would be greatly assisted by freezing seed first. I keep all my seeds outside in the gazebo actually. They for surely freeze solid in the wintertime, smiling. Think about nature, the plant (veggie whatever) drops its seeds after flowering has completed, the seeds are harboured ON top of the soil and then germinate. That is natural. Also, I wonder how many people know that the only reason that seed companies say to sprinkle seeds with a 1/4 inch covering of dirt. This is not because they need darkness to germinate, mostly to hold the seeds in place. Many seeds require absolutely darkness, hence a heavier covering of soil, but for the most part, most seeds will germinate without cover. Just some little things I know. Also, garlic bulbils, when they fall off the spent flower head of the garlic flower, when it has turned to seed, do not require covering up. I had a field of garlic greens that grew in our old life, where I didn't get around to gathering the flower heads and they fell over the winter. Interesting, the secret life of the plant. Have an awesome day, CynthiaM.
