Hello!
I recently received a packet of Maximillan sunflower seeds as a gift. It’s been stored in my freezer (unopened) and I had hoped to plant them this spring. Due to circumstances beyond my control, it doesn’t look like I’ll be able to plant them this season.
My questions are:
1. If I continue to store them in the freezer, will they be viable next spring?
2. If so, how long before I plant them, should I take them out of the freezer?
Some say that seeds should be stored in the refrigerator and others say the freezer. What’s your opinion?
Thanks so much!

If you're saving the seeds to re-plant, store them in an air tight container in a cool dry place until you are ready to plant. Label the container with the variety and the date you harvested. The seed will last for years if stored this way. If you’re going to store seeds in the freezer their moisture content needs to be VERY low - like in the 5% range and maybe less. It’s far easier to store seeds in a cool, dark spot. I don’t know how long you’re planning to store them. If you’re going to use them the next season you would be fine with almost any method.
