For most of the US this cold blast will be the last and it will be time to start getting our hands dirty. I have a 12 acre farm that fully supports my family and leaves plenty left over for storage and the future. While I'm biased a bit, I think it's time to bring back victory gardens.
Get out there, dig in the dirt, and plant some seeds.
Feel free to ask advice here!
Sorry, just got to this comment. You can buy organic seeds, and both MI Gardener and Seeds now also have some choices that they call heirloom seeds. You can look out for either of those options.
