In this article, we’ll explore the steps involved in growing green onions from onions, including the materials needed, the preparation process, and the care and maintenance required to ensure a successful harvest.
Understanding Green Onions and Their Growth Cycle
Before we dive into the process of growing green onions from onions, it’s essential to understand the growth cycle of these plants. Green onions, also known as scallions or spring onions, are a type of onion that is harvested before the bulb forms. They are typically planted in the early spring or late summer, and they take about 6-8 weeks to mature. Green onions are a cool-season crop, which means they thrive in temperatures between 60-70°F (15-21°C). They require minimal care and can be grown in a variety of conditions, making them an ideal choice for gardeners of all levels.
Materials Needed to Grow Green Onions from Onions
To grow green onions from onions, you’ll need a few basic materials. These include:
A container or garden bed with good drainage
Onion sets or onion bottoms (the root end of an onion)
Potting soil or garden soil
Water
A sunny location with partial shade
Optional: fertilizer, mulch, and pest control measures
Selecting the Right Onions for Growing Green Onions
When selecting onions for growing green onions, it’s essential to choose the right variety. Look for onions that are specifically labeled as “green onion” or “scallion” varieties. These onions are bred to produce long, thin stalks and small bulbs, making them ideal for harvesting as green onions. You can also use the bottoms of store-bought onions to grow green onions. Simply cut the onion about an inch from the root end, and use the bottom as a “set” to plant in your garden.
Preparing the Onion Sets for Planting
Once you have your onion sets or onion bottoms, it’s time to prepare them for planting. To do this, follow these steps:
Take the onion set or bottom and trim the roots to about 1-2 inches long. This will help prevent the roots from growing too deep and make it easier to harvest the green onions.
Trim the top of the onion set or bottom to about 1-2 inches from the top. This will help the onion focus its energy on producing new growth rather than seed.
Soak the onion set or bottom in water for about 24 hours to help rehydrate the roots and stimulate new growth.
Planting the Onion Sets
After preparing the onion sets, it’s time to plant them in your garden or container. To do this, follow these steps:
Fill your container or garden bed with a well-draining potting soil or garden soil.
Plant the onion set or bottom about 1-2 inches deep, with the trimmed top facing upwards.
Space the onion sets about 1-2 inches apart, depending on the variety and how large you want your green onions to grow.
Water the soil gently but thoroughly to settle the soil and provide enough moisture to support germination.
Caring for Your Green Onion Plants
Once your green onion plants are planted, it’s essential to provide them with the right care and maintenance to ensure a successful harvest. This includes:
Providing enough water: Green onions need consistent moisture to grow, especially when they’re producing new leaves. Water your plants regularly, but make sure not to overwater, which can lead to rot and other problems.
Providing enough sunlight: Green onions need partial shade to full sun to grow, depending on the variety. Make sure to provide your plants with at least 4-6 hours of direct sunlight per day.
Fertilizing: You can fertilize your green onions with a balanced fertilizer to promote healthy growth and development. However, be careful not to overfertilize, which can damage the plants.
Mulching: Mulching around your green onion plants can help retain moisture, suppress weeds, and regulate soil temperature. Use a thin layer of organic mulch like straw or bark chips around your plants.
Harvesting Your Green Onions
Green onions are typically ready to harvest about 6-8 weeks after planting, depending on the variety and growing conditions. To harvest your green onions, follow these steps:
Wait until the plants have reached the desired height and thickness. For most varieties, this will be around 6-12 inches tall and about 1/2 inch thick.
Cut the green onions at the base of the plant, just above the soil line. You can use scissors or a sharp knife to cut the onions.
Leave about 1-2 inches of the onion stem and roots intact to allow the plant to regrow. This will give you a continuous supply of fresh green onions throughout the growing season.
Tips for Regrowing Green Onions
One of the benefits of growing green onions from onions is that you can regrow them multiple times. To do this, simply follow these tips:
Leave the onion stem and roots intact after harvesting, as mentioned earlier.
Water the plant regularly to keep the soil moist and promote new growth.
Fertilize the plant lightly to promote healthy growth and development.
Wait for the plant to regrow, which can take anywhere from a few days to a few weeks, depending on the variety and growing conditions.

How do I prepare the onion for growing green onions?
To prepare the onion for growing green onions, start by cutting off the top of the onion, leaving about an inch of the bulb and the roots intact. This will help the onion to regrow and produce new green onions. Next, trim the roots of the onion to about half an inch long, taking care not to damage the base of the bulb. This will help the onion to absorb water and nutrients more efficiently.
After preparing the onion, place it in a container filled with water, making sure that the base of the bulb is submerged. The onion can also be planted in soil, but water is a more effective medium for growing green onions. Change the water every few days to keep it fresh and prevent the growth of bacteria. Within a few days, the onion will start to produce new green onions, which can be harvested and used in a variety of dishes.
How often should I water the onion while growing green onions?
Watering is a critical factor in growing green onions from onions. The onion should be kept in a container filled with water, which should be changed every few days to keep it fresh. The water level should be maintained at a level that keeps the base of the bulb submerged, but not so high that it covers the entire onion. Overwatering can lead to rot and other problems, while underwatering can cause the onion to dry out and stop producing new green onions.
The frequency of watering will depend on the temperature and humidity of the environment. In general, the onion should be watered every 2-3 days, but this may need to be adjusted based on the specific conditions. It is also important to monitor the onion for signs of water stress, such as droopy or wilted green onions. If the onion is not producing new green onions, it may be a sign that it needs more water or a change of water.

The growth rate of the green onions can be influenced by factors such as temperature and light. Green onions grow faster in warmer temperatures and with plenty of light. They can be grown indoors or outdoors, but they require a minimum of 4-6 hours of direct sunlight per day.
