I have heard many people say that when shtf happens they will plant a garden and grow things then. Most of my fruit trees needed three years to start producing and five to really produce well. Same with the garden, building up the soil and learning through trial and error takes time. If you wait till a real disaster happens to get started you are going to starve to death.As we all know, gardening is a learned thing. Experience is a great (and hateful as hell) teacher! I wish I'd paid more attention with my Mom and her parents and sisters....
