I learned from that site to inventory all food items at least once a year. After a couple years you will know what your family will eat of an item in one year. I try to not carry over very much as most food items lose value after a year.
I plan my gardens in December and have my seed orders sent in by December 20th. I use this site initially:
because it helps eliminate planting the same family of plants in an area several years running. Once made I make a paper copy on graph paper and that goes out to the garden with me. I do it in pencil and make changes and notes as I plant.
