Yes, onions grow underground as the bulbs are formed from compressed, underground stems. The fleshy modified leaves and central bud enveloped by the bulb develop beneath the soil’s surface.
Onions are a type of root vegetable, and their bulbs are packed with nutrients and minerals. The growth process of onions involves the foliage dying down in autumn, leading to the outer layers of the bulb becoming dry and brittle.
Onions can be grown from seeds, transplants, or small bulbs, and they are typically started in spring for a late summer or fall harvest. The cultivation and growth of onions are fascinating processes that provide insight into the complexity of root vegetables. While some vegetables grow above ground, onions thrive beneath the soil’s surface, developing into nutritious and flavorful bulbs. Understanding how onions grow, from the formation of their bulbs to the timing of their planting, offers valuable knowledge for gardeners and enthusiasts alike. Let’s explore the intriguing journey of onion cultivation, from underground growth to the bountiful harvests they yield.

Onion Anatomy
Onions are found underground as bulbs composed of shortened, compressed stems. These underground stems are enveloped by fleshy modified scale leaves surrounding a central bud. In autumn or spring for overwintering onions, the foliage dies down, and outer bulb layers become dry and brittle. Onions can be grown from seed, transplants, or small bulbs called sets, with planting times varying based on start type and local climate. Root vegetables like onions and garlic grow underground to absorb water and nutrients for packed vitamins and minerals. |
Cultivation Of Onions
Onions do indeed grow underground, with their bulbs being comprised of compressed, shortened underground stems along with fleshy modified scale leaves surrounding a central bud. As the foliage dies down in autumn, the outer layers of the bulb become dry and brittle, marking the onion’s readiness for harvesting.
Do onions grow underground like potatoes? |
Onions are root vegetables that grow underground, just like potatoes. The bulbs of onions are composed of shortened, compressed, underground stems surrounded by fleshy modified scale leaves that protect the central bud. In the autumn or spring, depending on the variety, the foliage dies down, and the outer layers of the bulb become dry and brittle. Onions can be grown from seed, transplants, or small bulbs called sets. Planting time varies based on the type of start and local climate. In northern gardens, onions are typically started in the spring for a late summer or fall harvest. Onions, like other root vegetables, absorb nutrients and water from the soil, making them packed with vitamins and minerals. |
Types Of Onions
Onions are found underground, with bulbs composed of stems, modified scale leaves, and a central bud. The foliage dies down in autumn, and the outer layers of the bulb become dry and brittle. Onions can be grown from seed, transplants, or small bulbs known as sets, with planting time varying based on the start type and local climate. Root vegetables like onions and garlic grow underground, drawing water and nutrients to pack them with vitamins and minerals.
Benefits Of Growing Onions
Onions are root vegetables that grow underground. The bulbs are composed of shortened, compressed, underground stems surrounded by fleshy modified scale leaves. Onions can be grown from seed, transplants, or small, immature bulbs called “sets.” Planting time varies depending on the type of start you are using as well as your local climate. Root vegetables like onions and garlic are packed with vitamins and minerals, as they absorb water and nutrients from the soil. |
Comparison To Other Root Vegetables
Onions are root vegetables that grow underground, similar to other root vegetables such as potatoes, parsnips, and garlic. The bulbs of onions are composed of compressed, underground stems surrounded by fleshy modified leaves. They absorb water and nutrients from the soil, making them rich in vitamins and minerals.
Onions are indeed grown underground, much like potatoes and other root vegetables. The bulbs of onions are composed of shortened, compressed, underground stems that are surrounded by fleshy modified leaves. These leaves form a protective layer around the central bud at the tip of the stem. As the foliage dies down in autumn or spring, in the case of overwintering onions, the outer layers of the bulb become dry and brittle. Onions can be grown from seeds, transplants, or small bulbs called “sets.” The planting time varies depending on the type of start and the local climate. In northern gardens, onions are typically started in spring for a late summer or fall harvest. Root vegetables like onions and garlic are packed with vitamins and minerals because their roots absorb water and nutrients that nourish the plants.Credit: www.thespruce.com
Signs Of Onion Maturity
Onions mature underground, with bulbs forming from compressed stems enveloped by fleshy scale leaves. The outer layers dry out in autumn before harvest. This process is similar to other root vegetables like sweet potatoes, parsnips, and garlic.
Onions grow underground as bulbs with compressed stems enveloped by scale leaves. The outer layers dry during autumn or in spring for overwintering onions. Onions are started from seeds, transplants, or small bulbs called sets. Planting time varies depending on the start type and local climate. Root vegetables like onions absorb water and nutrients underground and are rich in vitamins and minerals. |
Final Thoughts
Onions indeed grow underground as their bulbs consist of compressed stems enveloped by modified leaves. The foliage dies down in autumn, drying the outer layers of the bulb. Onions can be grown from seed, transplants, or sets, with planting time varying based on climate and type.
Onions are root vegetables that grow underground. |
Different Onion Varieties: Onions are composed of shortened, underground stems surrounded by fleshy modified leaves. |
