I have kept a small notebook with a page for each plant as I add them to my collection. I put important info on them in the notebook, i.e. date received, maybe price sometimes, Name, etc. then as they progress I make notes and dates. I then have a file on each species that I print out the info on the internet I have researched. It has worked well for me. Maybe it would help you keep your records. They are important if you are truly interested in keeping your plants happy. Good luck with your record keeping.
