When it comes to harvesting onions, it is generally recommended to leave the tops on until the onions are fully cured. This means allowing the neck of the onion to dry and shrivel up. Cutting off the tops before the neck is fully cured can actually create a potential entry point for bacteria and fungi, which can lead to rotting of the bulbs.
It is important to note that the tops of the onions play a crucial role in the curing process. They help to draw moisture out of the neck, allowing it to dry properly. By removing the tops prematurely, you disrupt this natural drying process and increase the risk of spoilage.
Onions with flowers should be used as soon as possible, as they tend to not store well. The energy that the onion plant puts into producing flowers can detract from the quality and storage potential of the bulbs. So, if you notice any onions with flowers, it’s best to use them promptly rather than trying to store them for an extended period.
In my personal experience, I have found that leaving the tops on onions until they are fully cured has resulted in better storage and longer shelf life. By allowing the neck to dry naturally, the onions become more resistant to rot and can be stored for several months.
To summarize, it is best to leave the tops on onions until they are fully cured. Cutting off the tops too early can introduce bacteria and fungi, leading to bulb rots. Onions with flowers should be used promptly as they do not store well. Following these guidelines can help ensure that your harvested onions stay fresh and flavorful for an extended period.
