Knowing when onions are ready to pick can be determined by observing a few key indicators. While there is no perfect size for onions, their readiness for harvest can be determined by their bulb size, the color and condition of the tops, and the stage of growth.
One of the primary signs that onions are ready to be picked is the size of the bulbs. Onions should be allowed to grow and mature fully before harvesting. This means allowing the bulbs to reach a size that suits your preference. Some people prefer smaller onions, while others prefer larger ones. It’s entirely up to you and your personal taste. Generally, the bulbs should be big enough to meet your requirements before considering harvesting them.
In addition to bulb size, the tops of the onions provide important clues about their readiness for harvest. As the onions mature, the tops will begin to turn yellow and start to fall over. This is a natural process and indicates that the onions are nearing their peak ripeness. The yellowing and falling over of the tops is a result of the plant redirecting its energy from the tops to the bulbs, signaling that they are ready to be harvested. It’s important not to wait too long after this stage, as onions can become overripe and prone to rotting if left in the ground for too long.
When the onions are deemed ready for harvest, it’s time to pull them up from the ground. This can be done by gently grasping the tops near the base of the plant and pulling upwards. If the soil is loose enough, the onions should come out easily. However, if the soil is compacted, you may need to use a garden fork or trowel to loosen the soil around the bulbs before pulling them.
After pulling the onions from the ground, it’s important to shake off any excess soil clinging to the bulbs. This can be done by gently tapping the onions or lightly brushing off the soil with your hands. Be careful not to damage the bulbs in the process.
Once the excess soil has been removed, the onions should be laid out to cure. Curing is the process of allowing the onions to dry and develop a protective skin. This can be done by laying them out in a single layer in a cool, dry, and well-ventilated area. It’s best to leave the tops of the onions attached during the curing process, as they help to preserve the bulbs and prevent moisture loss.
Curing typically takes a few weeks, during which time the onions will gradually develop a papery outer skin. This skin helps protect the bulbs and allows them to be stored for longer periods of time without spoiling. Once the onions have fully cured, they can be trimmed of their tops and roots, if desired, and stored in a cool, dry place for future use.
Knowing when onions are ready to pick involves considering the size of the bulbs, the color and condition of the tops, and the stage of growth. Harvesting onions when the bulbs are big enough for your preference and the tops have turned yellow and fallen over is generally a good indicator that they are ready. Remember to shake off excess soil, allow them to cure with the tops attached, and store them properly for long-term use.
