by

Growing onions in Zone 7 can be a rewarding experience, especially when planted in June. Proper harvesting techniques ensure you get the best flavor and storage life from your crop. This guide provides essential tips for harvesting onions that were planted in June in Zone 7.

Understanding Onion Maturity

Knowing when your onions are ready to harvest is crucial. Typically, onions are mature when their tops begin to yellow and fall over. In Zone 7, June-planted onions usually reach maturity between late August and early September, depending on the variety and growing conditions.

Signs of Readiness for Harvest

  • The tops have fallen over and begun to brown.
  • The neck of the onion feels firm when gently squeezed.
  • The skin of the onion is papery and dry.
  • There is a noticeable size increase compared to earlier growth stages.

Harvesting Techniques

Follow these steps to harvest onions properly:

  • Wait until the tops have fallen over naturally to avoid damaging the bulbs.
  • Use a garden fork or shovel to gently loosen the soil around the onions.
  • Carefully lift the onions from the ground, supporting the bulbs to prevent bruising.
  • Brush off excess soil gently without removing the papery outer layers.
  • Lay the onions in a dry, shaded area with good air circulation for curing.

Curing and Storage

Proper curing extends the storage life of your onions. Follow these steps:

  • Allow onions to cure in a shaded, well-ventilated space for 2-3 weeks.
  • Ensure the onions are not exposed to direct sunlight during curing.
  • Once the outer skins are dry and papery, trim the tops to about 1 inch and remove any loose outer layers.
  • Store onions in a cool, dry, and dark place with good airflow.

Additional Tips for Success

To maximize your onion harvest, consider the following tips:

  • Plant onions in well-drained soil enriched with organic matter.
  • Water consistently, especially during dry spells, to promote uniform growth.
  • Monitor for pests such as onion maggots and treat promptly.
  • Use mulch to retain soil moisture and suppress weeds.

By following these harvesting techniques, gardeners in Zone 7 can enjoy a bountiful onion crop from June planting. Proper timing, careful harvesting, and proper storage are key to delicious, long-lasting onions.
