Today when I was weeding in my woodland bed where I (among others) grow different Dactylorhiza species, I discovered some Dac seedlings.
I have only grown Dactylorhiza for about 5 years and have never found any seedlings until today. I was excited and looked through the whole bed for seedlings. I found quite a few, and what puzzled me was that almost all of them was in a row, almost as they have been sown as carrots in the kitchen garden.
But then I realized that the row was on top of a buried MDF fiberboard I have used to keep Convallaria majalis out of my Dactylorhiza bed.
By accident I have made a Dactylorhiza sow bed similar to the cardboard method, but in my garden under non sterile conditions using MDF fiberboard instead of cardboard!
