Don’t forget to actually utilize the data you’ve collected. Look over it from time to time, especially if you are doing something similar to what you’ve recorded before. (Use that search function on this site too for when you didn’t record things in the plantings list that are relevant to whatever you need to know. It’s easy to forget it’s there some days.)
You’ll be less impatient if you remember maybe you haven’t waited long enough for results because our memory isn’t always as good as we want it to be.
