I spreadsheet, too. I use Open Office, which allows different sheets within one file. Sheet 1 is a list of all tomatoes I have ever researched that I might be interested in, with descriptions, DTM, sources, etc. Sheet 3 is the garden layout, Sheet 4 is each year's tomato list and potentials for next year, sheet 5 is my crossbreeding program, etc. The garden layout is color coded by hours of sun each 2'x2' square gets. (I do sun studies). Then the different crops are boxed in by heavy boundary lines.
