Onions are typically grown from late winter to midsummer, and they have varying storage capacities. The best time to plant onions is in early spring or late March to April, once the ground is workable.
Fall is also suitable for onion sowing in some regions, such as Southern California, from October through December. Depending on the variety and location, the timing for planting onions may vary, so it’s best to consider local conditions and frost dates for optimal results.
Following specific planting and care guidelines can help ensure successful onion cultivation, yielding a bountiful harvest when the timing is right. Additionally, some may opt to start onions indoors in late winter for later transplantation, which can also influence the planting schedule.
When To Plant Onions
For optimal growth, plant onions in early spring as soon as the ground is workable. Timing typically falls in late March or April when the temperatures have stabilized, providing favorable conditions for healthy onion growth. Additionally, it’s important to consider the specific variety and its storage capacity for successful cultivation.

Growing Onions From Seed
Growing onions from seed requires choosing a variety that suits your needs. Ensure the soil has good drainage and is fertile. When sowing onion seeds, plant them in rows with adequate spacing. Consider using a row cover or fleece to protect young plants. For a late harvest, opt for sowing in late summer. Alternatively, you can plant sets for a quicker growth cycle. Consistent watering and weeding are essential for onion health. When harvesting onions, wait for the tops to dry before pulling them up. Learn how to store onions properly to extend their shelf life. |
Factors Affecting Onion Growth
The factors affecting onion growth include bolting, curing & storing, and storing onions. Bolting is the process in which onions produce flower stalks prematurely, leading to reduced bulb size and quality. There are several reasons why onions bolt, including genetics, temperature fluctuations, and day length. To prevent bolting, it is important to select suitable onion varieties and provide consistent growing conditions.
Curing and storing onions is crucial for their long-term preservation. After harvesting, onions need to be cured in a dry and well-ventilated space for about two weeks to allow the outer skins to dry and thicken, ensuring better storage. Properly cured onions can then be stored in a cool and dry location, such as a pantry or cellar, with good air circulation. Storing onions away from potatoes and other fruits and vegetables that release ethylene gas can help in prolonging their shelf life.

Tips For Successful Onion Growing
To grow onions successfully, it is important to know the right time to plant them. According to gardening experts, onions should be planted in early spring once the ground is workable, usually in late March or April. Planting sets outdoors during this time will ensure a successful onion crop.
Soil Preparation:
Before planting onions, it is important to prepare the soil properly. This involves removing any weeds, loosening the soil, and ensuring it is well-drained. Adding organic matter such as compost or well-rotted manure can also improve the soil’s fertility and structure. |
Starting & Planting:
Onions can be started from seeds or sets. Seeds can be sown directly in the garden in early spring, while sets are small onion bulbs that can be planted in late winter or early spring. When planting, make sure to space the onions properly to allow for good airflow and prevent overcrowding. |
Weeding:
Weeding is crucial for successful onion growing. Keep the area around the onions weed-free to prevent competition for nutrients and water. Regularly check for weeds and remove them by hand or with a hoe. |
Proper Onion Planting Spacing:
Proper spacing is essential for healthy onion growth. Onions should be spaced about 4-6 inches apart in rows, with 12-18 inches between rows. This allows each onion bulb to develop fully and reduces the risk of diseases. Be sure to follow the recommended spacing guidelines for the specific onion variety you are growing. |
Growing Onions From Sets
To grow onions from sets, plant them outdoors in spring once the ground is workable, usually in late March or April. These short-day onions thrive best when the temperatures are no longer likely to dip below freezing. Harvest the onions when the tops fall over naturally.
Recommended time for sowing onion sets: | Plant onion sets before the last frost for optimal growth. |
Planting onion sets before last frost: | It is best to plant onion sets before the final frost to ensure a healthy growth cycle. |
Harvesting And Storing Onions
Harvesting and Storing Onions: Knowing when onions are ready to harvest is crucial. Typically, the foliage will start to brown and fall over. To harvest, gently pull the onions from the ground, allowing them to dry in a warm, well-ventilated area. For proper onion storage, ensure they are completely dry before storing. Store onions in a cool, dry place with good air circulation to prevent mold and sprouting. Avoid storing onions with potatoes as they release moisture. |
