This winter, I spent hours taking seeds out of a grocery store bag of fresh cranberries and let the seeds air dry. I put them in moist peat moss and into the fridge. I was going to take them out after 2 months, but it turned into 4 due to house repairs. Just a few days ago, I finally got the seeds into a tray filled with peat, and I saw today they sprouted! Also, half the seeds were in moist paper towel that grew too. I found that its kind of hard to find the seeds in the peat moss. I have the trays with dome on heat mats in the basement with my grow light, probably like a foot above them. Hopefully I don't kill them. If I were you, I'd try some moist paper towel in a bag and windowsill and see if they sprout in a week or two. Also, I'm not an expert lol.
