The reason this subject is good to mention is because now that spring has arrived, you should know about shortages and pitfalls people faced before.  As it is aptly written, there is nothing new under the sun; therefore, the same dilemmas faced by people before will be faced again.  A survival garden may be just the thing your family needs, as it will passively produce food for your future.

Wartime brings real shortages in virtually every area of the economy, especially in the area of foodstuffs.  Rationing becomes the norm rather than the exception, and it is difficult for people to scrape out a bare subsistence.  During WWII, the Victory garden was recommended by the U.S. Department of Agriculture in a pamphlet published in 1943.  The gardens were recommended to have the following vegetables planted:

Spinach, Chard or Kale for greens; Cabbage; Lettuce; Tomatoes; Soy Beans; Snap Beans; Lima Beans; Peas; Asparagus; Carrots; Beets; Turnips; Parsnips; Onions; Strawberries; Raspberries; Radishes; Peppers; Onions; Pole Beans.

That's quite a list, but it is not comprehensive and many preppers suggest these 25 seeds to start their survival gardens for added nutrition.
