6. Harvest and Storage
When the top of your plants falls over and becomes yellow, it means that your plants are starting to mature. To speed up the ripening process of your onions, bend the tops down. When harvesting your onions, make sure to take extra care because a bruised onion can rot easily and this encourages further rotting of crops to set in. Pull your onions when the tops of your plants are already brown in color. Harvest your crops before the cool weather sets in. Before storing your harvested onions, allow them to dry first for several weeks. You can store your dried onions in your cellar or in any storage area that you want.
