If you have a piece of land to plant a garden you should do it. Perhaps, you live in a city with flower gardens around your house. If so consider using some of that land for a few vegetables and/or herbs. The less time from the soil to the table the better the flavor. Even if you can, freeze or dehydrate these foods they will taste better and healthier then products that are shipped in to your supper market.
Use the winter months to plan your garden. Plant what your family will eat and eat what you plant. Additionally, plant those things you have the ability to store in your home, by way of refrigeration, freezing, dehydration, and/or home canning. Be certain to use safe methods of storage and use in a safe manner. Use those foods your family prefers to eat raw as soon after harvesting from your garden as possible. Foods that are to be preserved for storage should be dated so that you use them while they are not only safe from bacteria and loose of nutrition. You can purchase books telling you specifically how to can, freeze and/or dehydrate. Purchase these book instructions and follow them carefully. Can, freeze and dehydrate only those foods that your family enjoys. There is no reason to store foods that little Johnny refuses to eat. There is no reason to believe that, because; you went to all the hard work needed to grow, prepare and serve on your table that little Johnny will eat them. Those things your family likes to eat fresh, only; should be planted in smaller quantities.
Having been raised on a farm; where we lived in a home that was planned for food storage through our the winter; I have planned my current home around food storage. We eat lots of fresh fruits and vegetables through out the summer. Lettuce and many other vegetables that are eaten in salads, etc. just do not store well on a long range basis. When I was a child living at home; I was sent to the basement with mothers shopping list so to speak. Carrots were stored in little moist sand. Onions were stored in sacks that could breath, in a cool place. Fruits and vegetables were bottled and processes for long term storage. You can obtain literature from your local extension agent. If you purchase a pressure canner it should have instructions for pressure and length of time. Be careful to follow these instructions to the letter. Not following these instructions could be hazardous to your families health.
Today we have many ways to store our food supplies through out the year. Consider those fruits and vegetables that your family enjoys. You may want to grow them in your yard, purchase them from your local supper market, or a fruit stand in a local agricultural area.
Consider growing those items that generally recognized as being best for freezing; canning; drying; pickling; juicing; making sauce; making jam, jelly and preserves; and store in some type of cold storage, (Be it a root cellar, basement, or outdoor storage area (where the temperature is moderate.) These food items should be stored at a low temperature; protected from freezing and excessive heat. The choice of where to store and in what quantities depend on what your family will eat and in what quantities and your climate.
New varieties and/or hybrids are being developed all the time, so keep a lookout for new and improved varieties.
