I have three pots of seeds which I stratified in the refrigerator in damp paper towels for about six weeks. I sowed the seeds on milled sphagnum and they are under CF lights in a terrarium. It has been four months since they were sown and I only have seedlings in one pot and not many of those seeds sprouted. I would think the seeds were okay when I received them - they came from the ICPS seed bank.
Does anyone have any ideas about what I can try now? Can I try to stratify again? Rub with sandpaper?
Thanks in advance for the help.
