Having moist potting soil is going to help, but I always add some water to them in the fridge when working on germination. I also add some peroxide, but that is just how I do it. I have seeds in the fridge that have been in there for close to 3 years now, and they haven't germinated, because they are stored dry. I've taken some of these seeds and put some moisture in with them, and they germinated. So, the seeds aren't bad. They just need moisture to get going.
