Does Green Onion Grow from Onion?
When it comes to growing your own onions, you may wonder if you can use green onions to produce new crops. The answer is, yes, green onions can grow from onions! But before we dive deeper, let’s explore what green onions and onions are, and how they are related.
What is a Green Onion?
A green onion, also known as scallions or spring onions, is a type of onion that is harvested before the bulb forms. They are a cool-season crop, and are typically grown in early spring or late summer when the weather is cooler. Green onions have a stronger flavor than mature onions and are often used in Asian cuisine.
What is an Onion?
Onions are a type of plant that belongs to the lily family. They are a warm-season crop and are typically grown in mid-summer when the weather is warm. Onions are a staple ingredient in many cuisines around the world and are used for their flavor, texture, and nutritional benefits.
Can Green Onions be Used to Grow New Crops?
The simple answer is, yes, green onions can be used to grow new crops. In fact, you can use the sets, or small bulbs, that form on the ends of green onions to grow new onions. This process is called "setting" or "propagation".
The Process of Setting
The process of setting involves:
- Harvesting: Cut the green onion just above the bulb to encourage the plant to put its energy into producing sets.
- Drying: Allow the sets to dry for a few weeks to harden the outer skin.
- Planting: Plant the dried sets in well-draining soil, about 1/4 inch deep and 1-2 inches apart.
- Caring: Water and care for the sets as you would regular onions.
Factors to Consider
While growing new onions from green onion sets is a great way to propagate, there are a few factors to consider:
- Variety: Not all green onion varieties are suitable for setting. Look for varieties specifically bred for setting, such as ‘Evergreen Long’ or ‘Beltsville Bunching’.
- Climate: Setting is best done in a cool, dry climate, as high temperatures and moisture can cause the sets to rot.
- Space: Make sure you have enough space to plant and care for the sets. Onions require about 4-6 inches of space between plants.
Table: Green Onion Varieties Suitable for Setting
| Variety | Description | Climate | Space |
|---|---|---|---|
| Evergreen Long | Long, cylindrical green onions | Cool and dry | 4-6 inches |
| Beltsville Bunching | Bunching variety with strong flavor | Mild and dry | 4-6 inches |
| Texas Grano | Onion sets that form on top of green onions | Hot and dry | 1-2 inches |
Conclusion
In conclusion, green onions can indeed be used to grow new crops. By harvesting, drying, and planting the sets, you can propagate new onions. While there are a few factors to consider, such as variety and climate, the process can be rewarding and produce great results. With the right conditions and care, you can enjoy a bountiful harvest of fresh onions from your very own garden.
Additional Tips and Resources
- Sow multiple sets: For a higher success rate, sow multiple sets and space them 1-2 inches apart.
- Keep the soil moist: Water the sets regularly, especially during the first few weeks after planting.
- Monitor for pests: Watch for pests like aphids and slugs, and take action if necessary.
