If you see green sprouts growing from an onion, it means the onion is growing back. By separating the sprouts inside the rind and planting in good soil, you can harvest many new onions in just one season.
Steps
Prepare sprouted onions
- If you don’t have a knife, you can peel the onions layer by layer with your bare hands.
- You can eat these layers of onions if they are still firm and crispy, as long as they are washed well before cooking. If onions are soft and mushy, discard them immediately. [2] X Research Source
- If the white roots are already in place, you can immediately plant the onion sprouts into the soil.
- If the roots of the onion sprouts are brown and dry, they are dead. You need to wait for new white roots to form.
Planting sprouted onions
- Whether growing indoors or outdoors, you need to make sure there is enough sunlight for your onions.
- If you live in a cold climate, plant sprouts in pots and gradually move them outside. Onions have been in the house for a while and need to gradually adjust to acclimatization. [4] X Research Sources
- During the winter in cold climates, keep plants indoors most of the time to help them survive. [5] X Research Sources
- Onions will gradually form after 60-80 days. [6] X Research Source
- If you use mulch, onions need only 2.5 cm of water per week. [8] X Research Sources
- If you prefer to grow organically, you can use solutions like hydrogen peroxide or copper sulfate to replace pesticides. [10] X Research Source
Harvest onions
- The onion completely emerges from the soil. [11] X Research Source
- The green sprouts wilt and turn brown.
- Flower stalks appear. [12] X Research Source
- You can skip the initial treatment and use it right away, but storing onions without drying them first makes them very susceptible to mold and rotting. [16] X Research Source
- If you can’t find a dry place to dry onions, you can consider using a dehumidifier to reduce the moisture in the onions. [17] X Research source .
Advice
- Spring is usually the best season to plant onions, but if you live in a temperate climate, fall or early winter is also quite suitable. [19] X Research Source
Warning
- If you suspect an onion is rotten or the onion looks soft and mushy, don’t eat it, just throw it away.
- You should note that only watering the soil around the base, not directly on the onion leaves. If you water the sprouts, the plant will become moist and attract fungal or bacterial spores. [20] X Research Sources
