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

  1. Planting Time:
    • 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:
    • Wet conditions can cause bulbs to rot before they’re harvested.
  3. Skipping the Curing Process:
    • Uncured onions are prone to spoilage and won’t store well.

FAQs About Harvesting Onions

  1. Can I harvest onions early if needed?

Why Grow Spring Onions in Water?

Growing spring onions in water is a simple, eco-friendly way to keep fresh onions on hand without the need for soil or a garden.

Benefits of Growing Spring Onions in Water:

✔️ Quick regrowth – Ready to harvest in just 5-7 days!
✔️ No soil or mess – Perfect for indoor kitchens.
✔️ Saves money – Regrow store-bought onions multiple times.
✔️ Sustainable & eco-friendly – Reduces food waste.
✔️ Minimal maintenance – Just change the water every few days!

How to Grow Spring Onions in Water: Step-by-Step Guide

Step 1: Select Your Spring Onions

✔️ Buy fresh, healthy spring onions from the store or farmers’ market.
✔️ Ensure the white bulbs have roots attached—this is essential for regrowth.

Tip: Organic spring onions tend to regrow better than conventionally grown ones.


Step 2: Prepare the Onions for Regrowth

1️⃣ Cut the green tops off, leaving 2-3 inches of the white root section.
2️⃣ Use the green tops for cooking, and keep the root base for regrowing.

Tip: The longer the white section, the stronger the regrowth!


Step 3: Place the Onions in Water

1️⃣ Fill a small glass or jar with fresh water (about 1-2 inches deep).
2️⃣ Place the spring onion roots down into the water, ensuring only the roots are submerged—not the whole bulb.
3️⃣ Place the jar on a sunny windowsill (indirect light is best).

Warning: Avoid submerging the entire white part, as it may cause rotting.


Step 4: Maintain & Change the Water Regularly

✔️ Change the water every 2-3 days to keep it fresh and oxygenated.
✔️ Rinse the onion roots lightly under running water when changing the water.
✔️ Keep them in a warm, bright location—indirect sunlight is ideal.

Tip: If the water turns cloudy, change it immediately to prevent bacteria growth.


Step 5: Harvest Your Spring Onions

✔️ After 5-7 days, the green shoots will grow 4-6 inches tall.

Spring onions can regrow 3-5 times in water before their roots weaken.

Regrowth CycleGrowth SpeedQuality of Onion

5th regrowth9-12 daysVery weak, may not grow much

After 3-5 cycles, it’s best to plant them in soil or start a new batch.
