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!
Make sure you rotate what you are growing. Tomatoes and cukes should not be grown in the same area year after year. Same for root vegetables. Doing so depletes the same nutrients.
Instead, grow tomatoes one year, carrots in the spot next year. A good gardening book will specify the crops to rotate.
