Super Potato Onion Nest Not So Super

I left one potato onion bulb/nest alone for a number of years to see what would happen, expecting a "super nest" with dozens of bulbs by the time I harvested it. That didn't happen as you'll see at the end of the video.
10/27/2021 I planted one small mother bulb so the top was covered with three inches of soil.
During the 2022 season, I left it alone. From the stalks that emerged, it appeared that one bulb grew beneath the soil.
During the 2023 season, a nest grew and some bulbs pushed up out of ground. The video starts July 2023 and ends July 2024 with the harvest of the final nest.
