Goodness, Betty. I could NEVER do that. When I said I made a diagram of my front yard iris, I meant I went out there with a sheet of paper and spent very few minutes making a rough sketch and just writing in the names of the iris.
One reason I don't have most of my yard mapped (besides lazyness) is that I am always moving things and would have to contantly redo my maps. I consider it a total waste of time to have to redo maps. It certainly would not be something I find enjoyable.
