Re: The best medium for seed germination in zip lock bags
Eventually the vermiculate still failed, but I think the cause may be that there's a heater right underneath the germination area, raising the humidity too high which maybe makes the seeds more prone to mold.
Anyways, I resorted back to the way that has always worked and planted them outdoors where they somehow tend to lose their mold and germinate in a natural environment. There must be something in the gardening beds that are erasing the mold whenever I plant them out. I have a few thousand tree peonies in the ground now so hopefully the plant tags don't get blown away because I want to have a firm ID of each species as they come up next spring or the spring after.
Maybe I just suck at germinating things in plastic bags. It seems like once there's an infection, spores can be spread throughout all the seeds within a couple minutes. My best germination of any seeds are straight into the soil outdoors during the growing season.
