keeping track of watering/fertilizing schedules

[bethmarie]

I've got mounted plants, plants in aliflor, bark, sphagnum...all different sized and kinds of pots--all different needs. I'm tracking when each one's watered, fertilized, repotted, etc using a calendar drawn on an x large sheet of sketch paper. Technologically speaking, it feels like the equivalent of etching stone with a chisel. There must be a better way to see at a glance all the info I'm tracking on my orchids. what do you use if you track these things?
