Just now a few days ago Stephen Barstow published a short video clip of how he stratifies hundreds of perennial vegetable seeds of a mindblowing variety in such a tiny space that you wouldn't believe it. In the small frame he uses milk cartons laid down on the side where he sows around 10 different varieties in each of the cartons, totaling to around 2-300 varieties each year, making sure plants from the same family isn't too close. "It’s just a wooden frame with Enviromesh draped over to stop mainly birch seeds from entering but allowing water to pass through."
Here's the link to the blog post that contains the video and further description:
Thanks to notoriously curious Benedicte Brun for asking him this simple question of how he does it!
Fun fact: He has aprox. 2000 varieties in his half an acre edible garden, and routinely makes a gimmick of putting hundreds of edible plants in a mixed salad. His record is over 500 different edible perennials in 1 salad, all coming from his garden.
This is the second post this week were someone was getting great propogating results in a wooden frame that looks no more complicated than nailing some scrap lumber together. I actually think I have corner of one bed that would be perfect for setting up a winter propagating station like this. It only gets full sun in the winter, but that would be long enough for germination.
