I have added irises this year. I did a basic map of where everything is that I planted. I was wondering how everyone did their mapping. Way I did mine is drew out the area that the beds were put and numbered them. Them on a separate sheet of paper I drew the bed and placed a number where each iris is. After that I made a legend in the open area of the paper as to what the numbers were iris wise (like 1 is apricot queen etc.). Kinda curios how others do it.
