Onions are ready for harvest when about two-thirds of their leafy tops have fallen over and dried naturally, and the necks of the onions have begun to dry as well.
Recognizing When Onions Are Ready
Harvesting at the right time is crucial for onion storage and quality. Here's what to look for:
- Fallen Tops: The most obvious sign is when the onion tops, which are the green, leafy parts, start to fall over. This indicates that the bulb is nearing maturity.
- Dried Tops: It’s not enough that the tops have fallen, they should also have started to dry out.
- Dry Necks: The "neck" of the onion is the part where the leaves meet the bulb. When onions are young and actively growing, these necks will be green and fleshy. As they mature, these necks will begin to dry out and shrink.
The Importance of Proper Timing
Harvesting at the correct time ensures:
- Optimal Bulb Size: Onions continue to swell until they reach maturity, so harvesting too early will result in smaller bulbs.
- Proper Curing: Onions need time to cure to ensure proper storage. This allows the outer skin to dry out, reducing the risk of rot.
| Feature | Immature Onion | Mature Onion |
|---|---|---|
| Tops | Upright, green | Fallen over, drying |
| Neck | Thick, green, fleshy or succulent | Drying out, thin |
| Bulb Size | Smaller | Larger |
| Storage | Will not store well | Stores well after proper curing |
Practical Considerations
- Weather: Avoid harvesting onions immediately after rain, as this can promote disease. Choose a dry, sunny day for harvest.
- Variety: Different onion varieties may mature at slightly different times, so pay close attention to your specific planting.
- Careful Handling: Be gentle when pulling onions out of the ground to avoid bruising or damaging them.
By using these guidelines, you can ensure you harvest your onions at the right time for the best quality and storage life.
