On a recent trip to a pick-your-own fruit and vegetables farm, I was fascinated how they had columns of fresh raspberries. They tasted lovely and sweet. I was inspired and wanted to figure out how to obtain raspberry seeds. I came across a video which involves food processing the raspberries and then squeezing the puree into a sieve leaving behind the seeds. The video explains that I would need to dry the seeds overnight. And he mentioned something about stratifying them.
What I want to do is ensure stratification either by leaving it in small pots outside and let nature take it's course, or to put the seeds in the freezer. I would prefer either as they both seem easy to do.
Can someone guide me please.
