@Laotionne - Canning is a good way to stock up on fruits and vegetables for the winter, but it isn't as simple as you might think. I'm not saying the process is difficult or overly complicated, but you need to know what you are doing. I think it's best to let someone show you how to do it before you try it by yourself.
One of the biggest mistakes some people make is that they do not sterilize everything properly. Canning jars must be placed in boiling water and sterilized thoroughly, or else your food might spoil. The lids have to be sterilized separately in a pan so that the seal isn't damaged. A damaged seal can also lead to spoiled food.
Just think how disappointing it would be to have jars of canned food and then find out that they are no good because you did something wrong.
