I freeze a lot of tomatoes and some peppers but that's about it. I make a lot of pasta sauce through the year so I grow 6 romas dedicated for cooking and all those plum tomatoes get frozen. Three early girls provide additional tomatoes for freezing so I can use mostly garden tomatoes for my sauces all year.
I have learned through the years how much to grow of a certain crop without having more than we need so I get a great variety of things during the growing season but not too much of anything - other than tomatoes. It works out to a savings of $1500 a year according to my calculations based on organic prices. And that doesn't count what I give to friends and neighbors.
wow, $1500 is significant!
Yes I tracked what I was getting for three years and it always came close to $1500. I was pricing it as organic which inflated the price but that is how I buy my food during the off season mostly and my garden is organic so I thought that was fair. Of course the berries account for a lot since organic berries are so expensive and I get so many in June and July. I would never buy that many berries if I wasn't growing them so it may not be considered true savings but you get the idea.
