If you have a lot of Tomatoes in your garden, you can freeze them whole. Wash and dry them first then place in a Ziploc bag. They will stay fresh for a long time, use for cooking or to make tomato sauce.
This is how I'm growing my Carrots this year. Learned it by accident last year. The post has a great tutorial. Wish I had it before my trial and error method :O) I might actually be able to grow carrots without critters eating them first if I do this!
