Onions are a kitchen staple and a rewarding crop to grow. Whether you’re a seasoned gardener or new to onion cultivation, understanding how to properly harvest, cure, and store onions is key to extending their shelf life up to a year. Follow this comprehensive guide to keep your onions fresh, flavorful, and ready to use in your favorite recipes.
Understanding When to Harvest Onions
The timing of your onion harvest is crucial. Onions are typically ready to harvest when:
- Tops Begin to Fall Over: The first signal is when about 80-90% of the onion tops bend over and turn yellow.
- Bulbs Reach Mature Size: Gently pull back some soil to check the size of the bulbs. They should feel firm and look well-formed.
Pro Tip: Harvest on a dry day to prevent excess moisture, which can lead to rot during curing or storage.
Step 1: Harvesting Onions
Harvesting onions is simple but requires care:
- Use a garden fork or trowel to loosen the soil around the bulbs gently.
- Pull each onion out by its neck, avoiding any rough handling that could bruise the bulbs.
- Shake off loose soil, but resist the temptation to wash them at this stage.
Why It Matters: Any damage to the onion’s skin can shorten its storage life, so handle with care.
Step 2: Cleaning and Preparing the Bulbs
After harvesting, the next step is to clean the onions:
- Brush Off Soil: Use your hands or a soft brush to remove dirt. Do not wet the onions, as moisture can encourage mold or rot.
- Inspect for Damage: Set aside any damaged or bruised onions for immediate use, as they won’t store well.
Step 3: Curing Onions for Long-Term Storage
Curing is the process of drying onions to prepare them for storage. This is a vital step that enhances their longevity:
- Choose the Right Spot: Find a warm, dry, and well-ventilated area, such as a garage, shed, or covered porch.
- Lay Onions in a Single Layer: Spread the onions out in a single layer on a clean, dry surface. Avoid stacking them, as airflow is essential.
- Keep Them Dry: Ensure they’re out of direct sunlight and away from moisture.
- Wait for 2-3 Weeks: Allow the onions to cure until the necks are dry and the outer skins are papery.
Signs of Proper Curing:
- The tops and roots should feel completely dry.
- The onion skin should crinkle when touched, and the necks should close tightly.
Step 4: Trimming the Tops and Roots
Once the onions are cured, it’s time to trim them:
- Tops: Cut the dried tops down to 1 inch above the bulb.
- Roots: Trim the roots close to the base without damaging the bottom plate of the bulb.
This process helps reduce the risk of mold and makes the onions easier to handle during storage.
Step 5: Sorting and Storing Onions
To maximize the shelf life of your onions:
- Sort Carefully:
- Separate storage-quality onions (firm and unblemished) from those with damage or soft spots.
- Use damaged onions immediately, as they won’t last long.
- Choose the Right Storage Method:
- Use mesh bags, baskets, or wooden crates to allow proper airflow.
- Avoid plastic bags, as they trap moisture and encourage rot.
- Pick the Ideal Storage Location:
- Store onions in a cool (32-40°F), dry, and dark place.
- Basements, root cellars, or cool pantries work well.
- Avoid Storing with Other Produce:
- Keep onions away from potatoes, as they release moisture and gases that can cause spoilage.
Step 6: Regular Monitoring
Even the best-stored onions require occasional checks:
- Inspect for soft spots, sprouting, or mold every few weeks.
- Remove any compromised onions to prevent issues from spreading.
Pro Tip: Sweet onions, such as Vidalia, have a shorter storage life compared to storage varieties like Yellow Globe or Copra. Plan to use these sooner.
Common Mistakes to Avoid
- Harvesting Too Early: Pulling onions before the tops naturally fall can result in underdeveloped bulbs.
- Skipping the Curing Process: Improperly cured onions are prone to rot.
- Storing in Humid Areas: High humidity leads to sprouting and decay.
Why Proper Onion Storage Matters
Storing onions correctly saves money, reduces waste, and ensures you always have fresh onions on hand. It also preserves the flavor and nutrients of your homegrown produce.
The Benefits of Homegrown Onions:
- Chemical-free and natural.
- Superior flavor compared to store-bought onions.
- A sense of satisfaction and self-sufficiency.

A: Check the necks; they should be completely dry and tightly closed. The outer skins should also feel papery.
Q: Can I braid the onion tops for storage?
A: Yes, braiding is an attractive and functional storage method for onions with intact, flexible tops.
