As the weather warms up and spring arrives, many gardeners notice a change in their spring onion plants. Instead of the usual green shoots, they start to produce flowers. This can be a bit of a surprise, especially for those who are new to gardening. But don’t worry, it’s a natural process, and there are several things you can do when spring onions flower. In this article, we’ll explore the reasons behind flowering spring onions, how to prevent it, and what to do with the flowers.
Understanding Spring Onion Flowering
Spring onions, also known as scallions or green onions, are a type of onion that is harvested before the bulb forms. They are a cool-season crop, which means they thrive in the cooler temperatures of spring and fall. As the weather warms up, the plants start to produce a flower stalk, which can grow quite tall. This is a natural process, and it’s a sign that the plant is mature and ready to produce seeds.
Why Do Spring Onions Flower?
There are several reasons why spring onions flower. One of the main reasons is the temperature. When the temperature rises above 65°F (18°C), the plant starts to produce a flower stalk. This is because the plant is trying to produce seeds, which will ensure its survival. Another reason is the day length. As the days get longer, the plant receives more sunlight, which triggers the production of flowers. Nutrient deficiency can also cause spring onions to flower. If the soil lacks essential nutrients like nitrogen, phosphorus, or potassium, the plant may produce flowers instead of leaves.
Preventing Spring Onion Flowering
While it’s not possible to completely prevent spring onions from flowering, there are a few things you can do to delay the process. One way is to provide the plants with partial shade, especially during the hottest part of the day. This will reduce the amount of sunlight the plant receives, which can help to delay flowering. You can also try pinching off the flower stalk as soon as it appears. This will help to direct the plant’s energy towards producing leaves instead of flowers. Another way to prevent flowering is to harvest the plants regularly. By harvesting the plants regularly, you can encourage them to produce new growth, which can help to delay flowering.
What to Do with Spring Onion Flowers
So, what can you do with spring onion flowers? Well, there are several options. One thing you can do is let them seed. If you allow the flowers to produce seeds, you can harvest the seeds and use them to grow new spring onion plants. This is a great way to save money and ensure a continuous supply of spring onions. Another option is to use the flowers as a garnish. Spring onion flowers are edible and can be used as a garnish for salads, soups, and other dishes. They have a mild onion flavor and a beautiful, delicate appearance.

What happens when spring onions flower?
When spring onions flower, it means that the plant has reached the end of its life cycle and is producing seeds. This process is also known as bolting, and it can be triggered by a combination of factors such as weather conditions, day length, and temperature. As the plant flowers, it will start to divert its energy from producing leaves and roots to producing seeds, which can affect the flavor and texture of the onions. The flowering process can also make the onions more prone to disease and pests, which can further reduce their quality.
It’s worth noting that flowering spring onions can still be used in cooking, but they may not have the same flavor and texture as those that are harvested before they flower. The green leaves and stems of the plant can still be used in salads, soups, and other dishes, but the bulbs may become tougher and more fibrous. If you want to prevent your spring onions from flowering, you can try to harvest them before they reach the end of their life cycle, or you can use techniques such as trimming the leaves and stems to encourage the plant to focus its energy on producing new growth rather than seeds.
How do I prevent spring onions from flowering?
Preventing spring onions from flowering requires a combination of proper care and maintenance, as well as some techniques to trick the plant into thinking it’s still in its vegetative phase. One way to prevent flowering is to provide the plants with consistent moisture and fertilization, which can help to promote healthy growth and prevent the plant from becoming stressed. You can also try trimming the leaves and stems of the plant to encourage it to focus its energy on producing new growth rather than seeds. Additionally, you can try to provide the plants with some shade, especially during the hottest part of the day, which can help to reduce stress and prevent bolting.
Another technique to prevent flowering is to use a process called “debulbing”, which involves removing the central bud of the plant to prevent it from producing seeds. This can be done by carefully cutting out the central bud with a sharp knife or pair of scissors, taking care not to damage the surrounding leaves and stems. It’s also important to harvest your spring onions regularly, as this can help to encourage the plant to produce new growth and prevent it from flowering. By using these techniques, you can help to extend the harvest period of your spring onions and keep them producing fresh, flavorful leaves and stems for a longer period.
Can I still use spring onions that have flowered?
Yes, you can still use spring onions that have flowered, but they may not have the same flavor and texture as those that are harvested before they flower. The green leaves and stems of the plant can still be used in salads, soups, and other dishes, but the bulbs may become tougher and more fibrous. The flowers themselves can also be used as a garnish or added to salads, and they have a mild onion flavor. However, it’s worth noting that the quality of the onions will decrease over time, so it’s best to use them as soon as possible after they have flowered.
If you want to use the bulbs of the spring onions that have flowered, you can try to dig them up and use them in cooking. However, be aware that they may be more prone to disease and pests, which can affect their quality and safety. It’s also important to check the bulbs for any signs of rot or mold, and to discard any that are damaged or spoiled. You can also try to dry the bulbs and use them as a spice or seasoning, which can help to preserve their flavor and aroma. By using these techniques, you can still get some use out of your spring onions even after they have flowered.

If you want to use the bulbs, you can try to dig them up carefully, taking care not to damage them. You can also try to twist the bulbs gently to loosen them from the soil, which can make them easier to remove.
It’s worth noting that harvesting spring onions that have flowered can be a bit more challenging than harvesting those that are still in their vegetative phase. The plants may be more prone to disease and pests, and the bulbs may be more difficult to remove from the soil.
