Grow Your Own Spring Onions: A Complete Guide
Spring onions, also known as scallions, are a versatile and delicious addition to any garden and kitchen. Their mild onion flavor adds a fresh zest to salads, soups, stir-fries, and countless other dishes. Growing your own spring onions is incredibly easy, even for beginner gardeners. They require minimal space, are relatively pest-free, and can be harvested in just a few weeks. This comprehensive guide will walk you through everything you need to know to successfully grow spring onions in your backyard or even in containers on your balcony.
## Why Grow Spring Onions?
Before we dive into the how-to, let’s explore the many benefits of growing your own spring onions:
* **Freshness:** Nothing beats the taste of freshly harvested spring onions. The flavor is more vibrant and intense compared to store-bought ones.
* **Cost-effective:** Spring onions can be quite expensive to buy regularly. Growing your own saves money in the long run.
* **Easy to grow:** They are one of the easiest vegetables to cultivate, making them perfect for beginner gardeners.

* **Tokyo Long White:** This variety is known for its long, elegant white stalks and its resistance to bolting (going to seed prematurely).
* **Evergreen Bunching:** As the name suggests, this variety is excellent for continuous harvesting and bunching. It is known for its strong regrowth ability.
When choosing a variety, consider your local climate, soil conditions, and taste preferences. You can find seeds or seedlings at most garden centers or online retailers.
## Step-by-Step Guide to Growing Spring Onions
Now, let’s get down to the nitty-gritty of growing spring onions. Here’s a detailed step-by-step guide to help you succeed:
### 1. Preparing the Soil
Spring onions thrive in well-drained, fertile soil. Before planting, prepare the soil by following these steps:
* **Choose a sunny location:** Spring onions need at least 6 hours of sunlight per day. Select a spot in your garden that receives ample sunlight.
* **Clear the area:** Remove any weeds, rocks, and debris from the planting area.
* **Loosen the soil:** Use a garden fork or tiller to loosen the soil to a depth of at least 12 inches. This will improve drainage and allow the roots to penetrate easily.
* **Amend the soil:** Add compost, well-rotted manure, or other organic matter to the soil to improve its fertility and drainage. Work the amendments into the soil thoroughly.
* **Check the pH:** Spring onions prefer a slightly acidic to neutral soil pH (6.0-7.0). Use a soil testing kit to check the pH and adjust it accordingly. If the soil is too acidic, add lime. If it’s too alkaline, add sulfur.
### 2. Planting Spring Onions
There are two ways to plant spring onions: from seeds or from seedlings (also known as sets). Both methods are relatively easy, but starting from seeds requires a bit more time and patience.
**From Seeds:**
* **Start seeds indoors (optional):** If you live in a cold climate, you can start seeds indoors 6-8 weeks before the last expected frost. Sow the seeds in seed trays or small pots filled with seed-starting mix. Keep the soil moist and provide adequate light. Transplant the seedlings outdoors when the weather warms up.
* **Direct sow seeds outdoors:** Once the soil has warmed up and the danger of frost has passed, you can direct sow the seeds outdoors. Sow the seeds about ½ inch deep and 1 inch apart in rows spaced 6-8 inches apart. Gently cover the seeds with soil and water thoroughly.
* **Thin the seedlings:** When the seedlings are a few inches tall, thin them to about 2-3 inches apart. This will give them enough space to grow and develop properly.
**From Seedlings (Sets):**
* **Purchase seedlings:** You can buy spring onion seedlings from most garden centers or nurseries. Choose healthy-looking seedlings with strong roots.
* **Plant the seedlings:** Dig small holes about 2-3 inches apart in rows spaced 6-8 inches apart. Gently remove the seedlings from their containers and place them in the holes. Make sure the roots are covered with soil.
* **Water thoroughly:** After planting, water the seedlings thoroughly to help them establish their roots.
### 3. Caring for Spring Onions
Spring onions are relatively low-maintenance, but they still require some basic care to thrive. Here are some essential tips:
* **Watering:** Water regularly, especially during dry periods. Keep the soil consistently moist, but avoid overwatering, which can lead to root rot. Water deeply when the top inch of soil feels dry.
* **Weeding:** Keep the planting area free of weeds. Weeds compete with spring onions for nutrients and water. Hand-pull weeds regularly or use a hoe to cultivate the soil.
* **Fertilizing:** Spring onions benefit from regular fertilization. Apply a balanced fertilizer every 2-3 weeks during the growing season. You can also use a liquid seaweed extract or fish emulsion to provide essential nutrients.
* **Mulching:** Apply a layer of mulch around the plants to help retain moisture, suppress weeds, and regulate soil temperature. Straw, hay, or wood chips are excellent mulching materials.
* **Pest and Disease Control:** Spring onions are generally pest-resistant, but they can be susceptible to onion flies and thrips. Inspect the plants regularly for signs of infestation. If you find pests, use insecticidal soap or neem oil to control them. Diseases are rare, but fungal diseases can occur in wet conditions. Ensure good air circulation to prevent fungal problems. You can also use a fungicide if necessary.
### 4. Harvesting Spring Onions
Spring onions are ready to harvest when they are about 6-8 inches tall and the stalks are about ½ inch in diameter. This usually takes about 3-4 weeks from planting, but it can vary depending on the variety and growing conditions.
* **Harvesting method:** To harvest spring onions, gently pull them from the soil. You can also use a small trowel to loosen the soil around the base of the plants before pulling them out.
* **Continuous harvesting:** For continuous harvesting, only harvest a few onions at a time, leaving the remaining ones to keep growing. You can also cut the green tops off, leaving the bulb base in the soil. The onions will regrow new tops within a few weeks.
* **Storing spring onions:** Freshly harvested spring onions can be stored in the refrigerator for up to a week. Wrap them in a damp paper towel and place them in a plastic bag or container. You can also freeze spring onions for longer storage. Chop them into small pieces and freeze them in a single layer on a baking sheet. Once frozen, transfer them to a freezer bag or container.
## Growing Spring Onions in Containers
If you don’t have a garden, you can still grow spring onions in containers. Here’s how:
* **Choose the right container:** Select a container that is at least 6 inches deep and has drainage holes. You can use a plastic pot, a terracotta pot, or even a recycled container.
* **Use a good quality potting mix:** Fill the container with a well-draining potting mix. Avoid using garden soil, as it can become compacted in containers.
* **Plant the seeds or seedlings:** Follow the same planting instructions as for growing in the garden.
* **Water regularly:** Container-grown spring onions tend to dry out faster than those grown in the ground. Water them regularly, especially during hot weather.
* **Fertilize regularly:** Fertilize every 2-3 weeks with a balanced fertilizer or liquid seaweed extract.
* **Place the container in a sunny location:** Spring onions need at least 6 hours of sunlight per day. Place the container in a sunny spot on your balcony, patio, or windowsill.
## Regrowing Spring Onions from Scraps
One of the coolest things about spring onions is that you can regrow them from the bulb base after using the green tops. Here’s how:
* **Save the bulb base:** After using the green tops of your spring onions, save the bulb base with about an inch of the white stalk attached.
* **Place in water:** Place the bulb base in a glass or jar filled with water, ensuring that the roots are submerged. Place the glass in a sunny location.
* **Change the water regularly:** Change the water every day or two to prevent it from becoming cloudy or stagnant.
* **Watch them grow:** Within a few days, you’ll see new green shoots emerging from the bulb base. The roots will also start to grow longer.
* **Plant in soil:** Once the roots are a few inches long, you can plant the regrown spring onions in soil. Follow the same planting instructions as for seedlings.
## Common Problems and Solutions
While spring onions are relatively easy to grow, you may encounter some common problems. Here are some solutions:
* **Yellowing leaves:** Yellowing leaves can be caused by overwatering, underwatering, nutrient deficiencies, or pest infestations. Adjust your watering schedule, fertilize regularly, and inspect the plants for pests.
* **Stunted growth:** Stunted growth can be caused by poor soil, lack of sunlight, or root rot. Improve the soil by adding compost or other organic matter, ensure adequate sunlight, and avoid overwatering.
* **Onion flies:** Onion flies can damage the roots and bulbs of spring onions. Use insecticidal soap or neem oil to control them. You can also cover the plants with a row cover to prevent the flies from laying eggs.
* **Thrips:** Thrips are tiny insects that can suck the sap from spring onion leaves. Use insecticidal soap or neem oil to control them.
