Green onions, also known as scallions or spring onions, are a popular ingredient in many cuisines around the world. They are easy to grow, require minimal maintenance, and can be harvested in as little as 60 days. One of the most interesting things about green onions is that they can be replanted, allowing you to grow new onions from the bulbs of previously harvested plants. In this article, we will explore the process of replanting green onion bulbs, including the benefits, challenges, and best practices for successful regrowth.
Understanding Green Onion Growth
Before we dive into the specifics of replanting green onion bulbs, it’s essential to understand how these plants grow. Green onions are a type of perennial plant, which means they can grow and thrive for multiple years if conditions are favorable. The plant consists of a bulb, which is the underground storage organ, and a set of leaves that grow from the center of the bulb. The leaves are what we commonly use in cooking, and they can be harvested at any stage of growth.
The bulb of a green onion is made up of multiple layers, each of which has the potential to form a new plant. When a green onion is harvested, the leaves are typically cut off, leaving the bulb intact. If the bulb is replanted, it can regrow new leaves, allowing you to harvest additional onions from the same plant.
The Benefits of Replanting Green Onion Bulbs
Replanting green onion bulbs offers several benefits, including:
- Reduced waste: By replanting the bulbs of previously harvested onions, you can reduce the amount of waste generated by your garden.

What are the benefits of replanting green onion bulbs?
Replanting green onion bulbs is a great way to extend the life of your onions and enjoy a continuous supply of fresh green onions. By replanting the bulbs, you can regrow new green onions in as little as 7-10 days, depending on the variety and growing conditions. This method also allows you to save money by not having to purchase new onions every time you want to use them in a recipe. Additionally, replanting green onion bulbs is a sustainable and eco-friendly practice, as it reduces food waste and minimizes the need for constant onion purchases.
The benefits of replanting green onion bulbs also extend to the health and flavor of your onions. When you replant the bulbs, they regrow with a more intense flavor and aroma than store-bought onions. This is because the regrown onions have not been subjected to the same level of processing and storage as commercial onions, which can affect their flavor and nutritional content. Furthermore, regrown green onions are higher in fiber, vitamins, and minerals, making them a nutritious addition to a variety of dishes, from salads to soups and stir-fries.
How do I prepare green onion bulbs for replanting?
To prepare green onion bulbs for replanting, start by cutting the onion about 1-2 inches above the base of the bulb, leaving the white and light green parts intact. This will help the onion regrow new green shoots. Make sure to leave the roots and the base of the bulb intact, as these are essential for regrowth. You can also trim the roots slightly to help the onion absorb water and nutrients more efficiently. Next, rinse the cut onion under cold running water to remove any dirt or debris, and gently pat it dry with a paper towel to prevent moisture from accumulating and causing rot.
Once the onion has been prepared, you can plant it in a container filled with well-draining soil, such as a potting mix or a garden bed with rich, fertile soil. Make sure the soil is moist but not waterlogged, as this can cause the onion to rot. Plant the onion at the same depth as it was originally, and water it gently but thoroughly. You can also add a balanced fertilizer to the soil to promote healthy growth and development. With proper care and conditions, your green onion bulb should regrow into a new, healthy onion in no time, providing you with a continuous supply of fresh green onions for your culinary needs.
