Fred - Thank you for clarifying. I label mine a similar way, except I label mine with the parentage names (only 1 label per cross regardless of # of seeds in each row). I later give them a number when I plant them in the ground. But do place a label in each planting hole ... just in case. Now I just hope those labels don't fade (or I am in trouble). I also did a map this year (for the first time) of my newest seedling bed. I don't trust my labels not to fade underground. I used pencil on each label, but still don't feel that confident they won't fade. I'll see what happens in the future.
Your long bed areas look awesome! I envy the room you have on your property! I have more new seedlings that I need to get in the ground. I want to do another full sun raised bed, but am running out of room in the backyard. Wished I had more backyard property. You are inspiring, Fred!
