I'm a visual learner, so photo records work best for me as well. I recently created a separate folder for each garden bed and moved relevant photos into their spot, renaming the photos by date (month-year). That has allowed me to visually track how each bed looks at a particular time of year and also how it has changed from year to year. In my "Kitchen Bed" folder, for example, a photo taken in 06-2010 is followed by one taken in 06-2011, etc. Makes for a good visual progression as I scroll through each folder. More than one for any given month simple get (2), (3), etc. added after the month-year.
