In survival gardening you don’t always need to have a garden to get the vegetables you need to put up for a season. Most of the time you can get fresh vegetables at stands along the road, provided they are in season, and most grocery stores will carry vegetables that are in season in other parts of the world. Which makes getting ready for any emergency a little bit easier?
Now what you need to do is canning which is my preferred method of preserving food for the winter. You can also freeze most vegetables but if power goes out in an emergency the food will thaw out and spoil. Using the canning process you can also preserve meats for about a year. Actually I look at it like this is enough food to last for one growing season and restock after the next growing season. So I try to finish up eating everything I canned from the last season.
Another way of preserving food is dehydrating. This removes the moisture from vegetables and meats preserving them for several months and the meat is a good source of protein.
