Green onions, also known as scallions or spring onions, are a versatile and flavorful addition to any dish. They're easy to grow from seed and can be used fresh or cooked in a variety of recipes. In this article, we'll go over the steps on how to grow green onions from seed and provide tips and advice for a successful harvest.
Choosing the Right Seeds
Before planting green onion seeds, it's important to choose the right ones. Here are a few things to keep in mind:
- Understanding different types of green onion seeds: There are two main types of green onion seeds: bunching onion and spring onion. Bunching onions have long, white stalks and are typically used in salads and stir-fries. Spring onions have a larger bulb and are used in a variety of cooked dishes. Decide which type of green onion you want to grow based on your intended use.
- Factors to consider when selecting seeds: When selecting green onion seeds, look for ones that are fresh and high-quality. Check the packaging for the date the seeds were packaged and the expiration date. Also, choose seeds that are specifically labeled for the type of green onion you want to grow.
- Where to find high-quality green onion seeds: You can find green onion seeds at most garden centers or online seed retailers. Look for reputable brands and read reviews before making a purchase. Additionally, if you're buying seeds in person, check the packaging to make sure they haven't been damaged or tampered with.

Preparing the Soil
Green onions prefer well-draining soil with good moisture retention. Here's how to prepare the soil for planting:
- Ideal soil conditions for growing green onions: Green onions grow best in loose, well-draining soil with a pH between 6.0 and 7.0. They also prefer soil that is rich in organic matter. If your soil is heavy, you may need to amend it with sand or perlite to improve drainage.
- Steps to prepare the soil: Start by removing any weeds or debris from the planting area. Then, loosen the soil to a depth of 8 to 10 inches using a garden fork or tiller. Add a layer of compost or well-rotted manure to the soil and mix it in thoroughly. This will help improve soil fertility and provide the nutrients that green onion seedlings need to grow.
- Adding amendments to improve soil fertility: If your soil is deficient in nutrients, you may want to add additional amendments such as bone meal or blood meal. Follow the manufacturer's instructions for the amount to use, and be careful not to over-fertilize, as this can burn the seedlings.
Planting the Seeds
Green onion seeds are small and should be planted shallowly. Here's how to plant them:
- Best time to plant green onion seeds: Green onions can be planted in the spring or fall, depending on your climate. In general, it's best to plant them 2 to 4 weeks before the last frost date in your area. If you're planting in the fall, be sure to give the seedlings enough time to grow before the first hard frost.
- Choosing the right location for planting: Green onions need full sun to grow properly. Choose a location in your garden that receives at least 6 hours of direct sunlight per day. If you're short on space, you can also plant green onions in containers on a sunny balcony or patio.
- Steps for planting the seeds: Use a garden hoe or trowel to make shallow furrows in the soil, about 1/4 inch deep. Space the furrows about 12 inches apart. Sprinkle the green onion seeds evenly along the furrows, about 1 inch apart. Cover the seeds with a thin layer of potting mix or soil and gently water the area. Keep the soil moist until the seeds germinate, which can take 7 to 14 days.
Caring for Green Onion Seedlings
Green onion seedlings have shallow root systems and require consistent soil moisture. Here are some tips for caring for them:
- Watering requirements: Keep the soil consistently moist but not waterlogged. Water the seedlings deeply once or twice a week, depending on weather conditions. Be sure to water the soil around the base of the plants, rather than spraying the leaves.
- Fertilizing the seedlings: Green onion seedlings don't require a lot of fertilizer, but you can apply a balanced fertilizer once a month to help promote growth. Avoid using fertilizers high in nitrogen, as this can cause the plants to produce more foliage than bulbs.
- Controlling pests and diseases: Green onions are generally easy to grow and not prone to many pests or diseases. However, you may need to watch out for aphids, thrips, or onion maggots. You can prevent these pests by keeping the area around the seedlings clean and removing any dead plant material. If you do notice an infestation, you can treat it with insecticidal soap or neem oil.
Harvesting and Using Green Onions
Green onions are ready to harvest when the stems reach about 6 inches in length. Here's how to harvest and use them:
- Signs that green onions are ready to harvest: Look for green onions that have a healthy, firm stem and no signs of wilting or yellowing. You can also gently pull up on the stem to test if it's ready to harvest. If the stem comes up easily, it's ready to be harvested.
- Harvesting techniques: To harvest green onions, use a sharp pair of scissors or garden shears to snip the stem at the base. You can harvest individual stems or the whole clump. Be sure to leave at least one-third of the plant intact to allow for regrowth.
- Creative ways to use fresh green onions: Green onions are great for adding flavor to salads, soups, stews, and stir-fries. You can also use them as a garnish for tacos, sandwiches, or baked potatoes. Another creative way to use green onions is to make a homemade pesto or salsa verde.
Conclusion
Growing green onions from seed is an easy and rewarding process. By choosing the right seeds, preparing the soil properly, and caring for the seedlings, you can have a bountiful harvest of fresh, flavorful green onions. Whether you're a seasoned gardener or a beginner, growing green onions is a great way to add flavor and nutrition to your meals. So go ahead and plant some green onion or scallion seeds in your garden beds, and enjoy the fruits of your labor in no time! Don't forget to cover the soil with a layer of mulch to retain moisture and prevent weed growth.
