Undercutting the onions
Onions roots grow just below the surface on the dirt and and before they are harvested they need to be undercut. That is the process of lifting the onions out of the dirt and laying them back down. This process is usually done when the onion tops have started to dry down and the growing process has stopped. The process happens at a very slow pace and can only be done with the perfect weather conditions so that the onions are not damaged.
