Why Timing Matters When Harvesting Onions

Harvesting onions at the right time ensures:

• Optimal Flavor: Onions harvested too early may lack full flavor.
• Better Storage: Mature onions last longer in storage.
• Healthy Bulbs: Proper timing reduces the risk of rot or disease.
• Maximum Yield: Fully developed onions provide the best crop.

Signs That Onions Are Ready to Harvest

Look for these key signs to determine if your onions are ready to harvest:

1. Top Leaves Yellow and Fall Over:
   • Mature onions naturally signal readiness when their green tops begin to turn yellow and flop over.
2. Bulb Size:
   • Check the bulb size; it should be firm and large, depending on the variety.
3. Drying Neck:
   • The neck (where the green tops meet the bulb) becomes soft and shrinks as the onion matures.

When to Harvest Spring-Planted Onions

1. Planting Time:
   • Spring-planted onions are usually ready to harvest in late summer (July to August).
2. Maturity Period:
   • Onions take about 90-120 days to mature from planting.
3. Seasonal Signs:
   • Harvest when the tops have turned yellow and fallen over, usually in mid to late summer.

When to Harvest Overwintered Onions

   • Overwintered onions, planted in autumn, are ready to harvest in early summer (June to July).
2. Maturity Period:
   • These onions take about 6-8 months to reach full maturity.
3. Seasonal Signs:
   • Harvest as soon as the tops begin to yellow and fall over.

How to Harvest Onions

Follow these steps for a successful harvest:

1. Check the Soil:
   • Ensure the soil is dry to make harvesting easier and reduce the risk of rot.
2. Loosen the Soil:
   • Use a garden fork or trowel to gently loosen the soil around the onion bulbs.
3. Pull Onions Gently:
   • Grasp the onion at the base of the leaves and gently pull it out of the soil.
4. Inspect the Bulbs:
   • Remove any damaged or diseased onions to prevent contamination.

Curing Onions for Long-Term Storage

Curing is essential for onions you plan to store:

1. Lay Onions Out:
   • Place onions in a single layer in a warm, dry, and well-ventilated area. Avoid direct sunlight.
2. Allow to Dry:
   • Leave the onions to cure for 2-3 weeks. The outer skin should become papery, and the neck should fully dry.
3. Trim the Tops:
   • Once cured, trim the tops to 1 inch and remove any excess dirt.

How to Store Harvested Onions

Proper storage keeps onions fresh for months:

1. Choose a Cool, Dry Place:
   • Store onions in a space with temperatures between 2°C and 7°C (36°F-45°F).
2. Use Mesh Bags or Crates:
   • Allow good air circulation by storing onions in mesh bags, baskets, or ventilated crates.
3. Avoid Storing Near Potatoes:
   • Potatoes release moisture that can cause onions to spoil.

Common Harvesting Mistakes to Avoid

1. Harvesting Too Early:
   • Premature harvesting results in small, underdeveloped onions.
2. Leaving Onions in Wet Soil:
