What Are Spring Onions?

Spring onions are often confused with scallions, but they are actually different varieties of alliums. While scallions are perennial and do not form large bulbs, spring onions produce bulbs that are harvested while still immature. These spring onions are harvested quickly after picking, without curing, and are not intended for long-term storage. They offer a more pungent flavor compared to scallions and are perfect for fresh eating and cooking early in the season.

Propagation

There are several options for starting spring onions, each with its own advantages. You can plant seeds outdoors by preparing the soil and sowing as soon as the ground can be worked. Onion sets are another option, which are tiny, dormant bulbs that can be planted a few weeks before the last frost date. Transplanting slips, which are thin seedlings, is also a viable option for a faster harvest.

How to Grow Spring Onions

To grow spring onions successfully, it’s important to ensure they are planted in well-draining soil with plenty of organic matter. The plants require full sun and regular watering to thrive. Mulching and providing supplemental water are important steps to keep the plants healthy throughout the growing season.

Growing Tips

Here are some essential growing tips to keep in mind when cultivating spring onions:

• Plant in well-draining soil amended with plenty of organic matter. – Give plants an inch of supplemental water per week when rain isn’t sufficient. – When the tops are a few inches tall, mulch with a few inches of herbicide-free grass clippings, pine straw, or shredded leaves.

Where to Buy

If you are looking to purchase spring onion seeds or sets, there are various options available from retailers such as Burpee. Whether you prefer red, white, or yellow onions, you can find a wide selection to suit your needs.

Managing Pests and Disease

While spring onions are relatively resilient, there are a few pests and diseases to watch out for. Allium leafminers, onion maggots, slugs, and thrips are common pests that may affect your crop. Botrytis fungi can also cause disease in these plants, but proper prevention and treatment strategies can help minimize the impact.

Harvesting Spring Onions

Knowing when and how to harvest spring onions is essential to ensure you get the best flavor and texture. Harvesting can begin once the tops are at least four inches tall, and the main stalk is half an inch wide. Depending on when you planted and the variety you are growing, harvest times can vary from 21 to 40 days for sets and 60 to 80 days for seeds.

Storage and Preserving

While early-harvested spring onions are best enjoyed fresh, you can preserve them for future use. Freezing, dehydrating, or pickling are all viable methods to extend the shelf life of your harvest. By following proper preservation techniques, you can enjoy the flavors of spring onions year-round.

Recipes and Cooking Ideas

Spring onions can be used in a variety of dishes to add a fresh, savory flavor. From salads to soups, stir-fries to grilled dishes, the possibilities are endless. Their unique taste and versatility make them a valuable addition to any kitchen.
