There are a so many different ways to do this. I tried the germination in the baggies in the fridge one time and none germinated. But from the article in the Daylily Journal fall 2010, the goal is not to have them germinate in the fridge. You want the cold temps in the fridge to break dormancy and then they will germinate faster once they are at room temp.
I have tried the damp paper towels to germinate and it works ok but to me it's just too much trouble. Rich on the auction also mentions the vermiculite in his "about me" . He doesn't have any listings right now so you can't see his "about me" page.
The article used vermiculite, perlite, sand, coffee filter. They put the seeds in each medium in the fridge for 4 weeks and them removed them and put them at room temp. It still took seeds up to 4 weeks to geriminate. The highest germination was in the vermiculite, 97% germination after 4 weeks at room temp. Results for sand and perlite were equally good it says.
I guess if starting them indoors or you have very limited space for seedlings it would be good; to me it is just too much trouble to do all the pre-germination.
If it takes 2-4 weeks (sometimes longer) to get germination by soaking or whatever method is used, I could go ahead and plant them in the seed trays and still wait that long for them to germinate. I have heard some people say they get germaination after 3 days or a week by soaking in the H2O2 water. I have a lot already poking their heads up after 3 days just by planting them in the seed trays.
My thing is why do all the extra work, if I put them in the fridge for 4 weeks that a whole month they could have already been planted and growing and then I'm a month behind on planting. But here we have to get the seedlings in the ground by Sept 15th so we really need all the seeds planted by Aug 1st in order for most to be 5-6 weeks along.
I'm sure other peole will chime in because some on here have used various methods.
