As a new plant mom I searched high and low for a plant tracking app that could also help me troubleshoot. There are a lot out there, but most of them didn't fit exactly what I needed, or just had a subscription that didn't feel worthwhile. So I made my own in AirTable. In addition to water logs, I have potting and feeding logs. I also have a sheet that tracks the plants who are in "intensive care" or simply propagating. It's still a work in progress for my liking, but I hope you find it to be a good jumping off point. And yes, all of my plants are named after The Office.
