People have shown that you can regrow bulbs of scallions by submerging partially in water. I am aware plants only need sunlight, CO2, and water to produce energy, but I was also impression plants needed trace amounts of nitrogen and some minerals and metals to grow as well. Would scallions grown in just water be able to grow forever without any minerals? And by that logic wouldn’t these scallions also contain no minerals when eaten?
