How to Get Onion Seeds: A Comprehensive Gardening Guide
How to Get Onion Seeds?
To get onion seeds, start by choosing mature onion plants and allowing their heads to dry out completely.
It’s important to avoid harvesting onion seeds from hybrid onions.
Keep in mind that onions are biennial and only produce seed during their second year.
Choose onion bulbs for seed, store them over the winter in a cool environment (45 to 55 degrees F or 7-13 C), and replant them in early spring.
Onions produce flower balls that need to be pollinated.
While self-pollination is common, cross-pollination can occur and should be encouraged.
Harvest the onion seeds when the flowering heads turn brown.
To obtain the seeds, harvest the onion heads and place them in a bag.
Store the bag in a cool and dry place for a few weeks.
Once the onion heads are fully dry, shake them vigorously inside the bag to release the seeds.
Ensure the seeds are kept cool and dry during the winter.
Key Points:
- Choose mature onion plants and let their heads dry out completely.
- Do not harvest onion seeds from hybrid onions.
- Onions only produce seeds during their second year.
- Store onion bulbs in a cool environment over winter and replant in early spring.
- Onions produce flower balls that need to be pollinated.
- Harvest onion seeds when the flowering heads turn brown and store them in a bag in a cool and dry place for a few weeks.
Did You Know?
1. Onion seeds are not actually seeds, but small dry fruits that contain the true seeds.
2. Onions produce different types of seeds depending on how they are planted. Seeds from onions grown from bulbs will produce larger bulbs, while seeds from onions grown from seeds will produce smaller bulbs.
3. Onion seeds have a unique way of dispersal. When the seed capsules dry, they burst open forcefully, propelling the seeds up to 3 meters away.
4. Onion seeds have a long and rich history. They have been found in ancient Egyptian tombs, with evidence that they were used both medicinally and for culinary purposes.
5. Onions have been traditionally associated with various superstitions and folklore. In some cultures, placing onion seeds under one’s pillow is said to bring vivid dreams, while in others, it is believed to protect against evil spirits.
Choosing The Right Onion Plants For Seed Harvesting
When obtaining onion seeds, selecting mature onion plants is crucial. It is advised to allow the heads to dry out completely before harvesting the seeds. This drying process is essential for preserving the integrity and quality of the seeds. As the onion plants mature, the heads will naturally dry and turn brown, indicating that they are ready for seed harvesting.
The Process Of Harvesting Onion Seeds
Harvesting onion seeds is a straightforward process that can be done in your own garden. When onion heads have completely dried and turned brown, it’s time to start harvesting the seeds. Begin by carefully cutting the flower heads from the plant using sharp garden shears or scissors. Then, place the harvested onion heads in a bag and label it appropriately.
The Importance Of Avoiding Hybrid Onions For Seed Harvesting
While onion seeds are readily available in stores, it is important to understand that obtaining onion seeds from hybrid onions should be avoided.
Hybrid onions are created by cross-pollinating different onion varieties to produce desired traits such as disease resistance or increased yield. However, when it comes to seed harvesting, using hybrid onions can result in unpredictable seed production.
It is best to opt for non-hybrid onion varieties to ensure consistent and reliable seed harvesting.
- Hybrid onions should be avoided for seed harvesting
- Non-hybrid onion varieties are recommended for consistent seed production
Understanding The Blooming And Seed Production Of Onions
Onions are biennial plants, meaning they have a two-year life cycle. During the first year, onions focus on growing bulbs and establishing root systems. It is only in the second year that onions bloom and produce seeds. As the flower stalks grow, they ultimately produce balls covered with tiny flowers ready for pollination. It is during this stage that you can encourage cross-pollination to create diverse and genetically dynamic onion seeds.
Storing And Replanting Onion Bulbs For Seed Harvesting
To ensure successful seed harvesting, it is crucial to store onion bulbs over the winter. Store the bulbs in a cool and dry place, ideally at a temperature of 45 to 55 degrees Fahrenheit (7-13 degrees Celsius). This dormant period allows the bulbs to maintain their vitality and be ready for replanting in the early spring.
When replanting the onion bulbs, make sure to select a suitable location with well-draining soil and sufficient sunlight.
- Store onion bulbs in a cool and dry place (45-55°F / 7-13°C).
- Aim for a dormant period to maintain bulb vitality.
- Select a suitable location with well-draining soil and sufficient sunlight.

Promoting Successful Pollination For Onion Seed Production
Onions are typically self-pollinating, meaning that they can pollinate themselves without assistance. However, cross-pollination can also occur, leading to the production of genetically diverse seeds. To promote successful pollination, it is recommended to encourage insect activity in the garden by cultivating a diverse range of flowers and avoiding the use of harmful pesticides. Bees and other pollinators play a vital role in the pollination process, helping to ensure a plentiful seed harvest.
Obtaining onion seeds requires careful consideration and adherence to certain guidelines. By choosing mature onion plants, allowing the heads to dry completely, and avoiding hybrid varieties, gardeners can set themselves up for successful seed harvesting. Understanding the blooming and seed production process, as well as proper storage and replanting techniques, further enhances the chances of a bountiful onion seed harvest. By embracing and promoting natural pollination methods, gardeners can create a diverse and thriving onion seed collection. Happy gardening and may your onion seed endeavors be fruitful!
Frequently Asked Questions
How do you get seeds from an onion plant?
To obtain seeds from an onion plant, it is essential to wait until the flower head has fully opened. Once the flower turns brown and dries on the plant, carefully cut it off using scissors. Then, separate the individual umbels and collect the seeds from them. Remember to store the seeds in a cool and dry location until you are ready to germinate them.
How is onion seeds produced?
Onion seed production follows a unique process separate from the growth of onion bulbs or vegetables. It involves two distinct seasons to ensure high-quality seeds. During the first season, farmers focus on cultivating top-notch onion bulbs. These bulbs are carefully nurtured for their size, shape, and overall quality. In the second season, these quality bulbs are replanted to allow for true seed production. Through this approach, onion seeds are produced by growing and harvesting bulbs specifically dedicated to seed production, ensuring the development of robust and genetically stable seeds.
How many onions do you get per seed?
When it comes to onions, the result is quite straightforward – each onion set or seed gives rise to a single onion. Whether you opt for planting onion sets or sowing onion seeds, the outcome remains consistent – one mature onion per set or seed. This allows for easy calculation and planning, ensuring that you obtain the desired quantity of onions based on the number of sets or seeds you have available.
Do onion bulbs have seeds?
No, onion bulbs do not have seeds. Onion sets, which are small bulbs used for planting, grow foliage and bulbs in the first season, and in the second season, they bloom and set seeds. However, growing the sets themselves is considered one growing season. The sets are then ready to reproduce by producing flowers and setting seeds once they are planted in the garden. So, while the onion plant does eventually produce seeds, the bulbs themselves do not contain them.
