Harvesting red onions at the right time is crucial for a great yield and storage. Here’s how to know when to take them out of the ground and how to dry them properly for the best results.

When to Harvest Red Onions

  1. Check the Tops: Red onions are ready to harvest when the tops start to fall over and turn yellow. This usually happens about 100 to 120 days after planting.
  2. Inspect the Bulbs: Gently dig around the bulbs with your fingers. If they are firm and at least the size of a golf ball, they are ready to be harvested.
  3. Weather Matters: It’s best to harvest on a dry day. If the ground is wet, it can be more challenging to dig them out and may lead to rot during storage.

How to Dry Red Onions Properly

  1. Remove from Soil: Carefully pull the onions from the ground, being gentle to avoid bruising the bulbs.
  2. Trim Leaves: Cut the tops off, leaving about an inch of stem. Don’t trim the roots just yet; this helps protect the bulb during drying.
  3. Cure the Onions: Lay the onions out in a single layer in a warm, dry, and well-ventilated area. You can use a porch, shed, or garage. Make sure they are not in direct sunlight, as this can cause them to spoil.
  4. Drying Time: Allow the onions to cure for about 2 to 4 weeks. You’ll know they’re ready when the skins are papery and the necks are completely dry.
  5. Store Carefully: Once dried, trim the roots and any excess tops. Store your red onions in a cool, dark place, such as a pantry or basement, in mesh bags or crates for good air circulation.

By knowing when to harvest and how to dry red onions properly, you can enjoy your homegrown produce for months to come. Happy gardening!
