Thanks for the clarification! I’ve never ever tried to plant carrots, so this would be a new adventure for me if I “screw my courage to the sticking place”* and attempt it!

I remember as a kid on the farm, we would pull carrots that had double bottoms. We had a large garden - over one acre - and never went hungry. The rows were about 100 feet long and three feet apart, so you can imagine all the food that acre produced. Carrots usually were about one half of a row.
