I track my plants w/ Paint (MS program)
Once set up it's easy to make daily changes; at year's end, I erase all the containers and annuals and re-enter them where placed the next year.
I also track my lily collection hereon (goes back 6 years in the illustration) as well as columns for bulbs, annuals, self-seeders, perennials, vines, sightings for butterflies, Hummingbird Moths, and Hummingbirds and tomatoes.
