This is a convenient way to track your plants’ progress as you let them grow. Track perennials through multiple seasons, track annuals while they are around. Draw sketches, add photos, create a feeding schedule, or create a watering schedule.
Keep observations on what plants work for you as you write your experiences with them. Keep detailed notes on your observations, such as what food each plant responds to, what type of soil works for each one.
Record daily, weekly, or monthly observations about plant health, blooming, etc. That way or you can track your plant’s health over a long period to bring you closer to your plants. You may enjoy your hobby a little better, gain insight, and have a permanent record for when your plants are gone.
