What To Know
- If the outer layers of the onion are dry or damaged, peel them off to expose the fresh, green layers.
- Use your finger or a small trowel to create a hole in the soil about 1-2 inches deep.
- You can fertilize your green onions with a balanced liquid fertilizer every few weeks, especially if you’re growing them in a pot.
Are you tired of throwing away the green tops of your store-bought onions? Did you know that you can easily regrow those discarded scraps into fresh, flavorful green onions? Learning how to grow green onions from store bought is a simple and rewarding gardening project, perfect for beginners and seasoned gardeners alike. Not only will you save money, but you’ll also enjoy the satisfaction of harvesting your own homegrown produce.
Getting Started: Choosing the Right Onions
The first step to successfully growing green onions from store-bought is choosing the right onions. While you can try regrowing any type of onion, some varieties are better suited for this purpose. Look for:
- Scallions or Spring Onions: These varieties are specifically bred for their long, tender green stalks and are the easiest to regrow.
- Green Onions: These are also known as “bunching onions” and are similar to scallions but have a slightly stronger flavor.
- White Onions: While not as ideal as scallions or green onions, you can still regrow white onions, but they may produce smaller green tops.
Preparing Your Onion Tops for Regrowth
Once you’ve chosen your onions, prepare the tops for regrowing:
1. Trim the Roots: Cut off the bottom two inches of the onion, where the roots were attached. This will encourage new root growth.
2. Remove the Outer Layers: If the outer layers of the onion are dry or damaged, peel them off to expose the fresh, green layers.
3. Cut the Tops: Cut the green tops to about 2-3 inches in length. This will help the plant focus its energy on root development.
Selecting the Right Growing Environment
Green onions thrive in well-drained soil and prefer full sun to partial shade. Here are a few options for growing your regrown onions:
- A Pot or Container: Choose a pot with drainage holes and fill it with potting soil. Make sure the pot is large enough to accommodate the roots as they grow.
- A Garden Bed: Prepare a garden bed by loosening the soil and incorporating compost or fertilizer. Green onions prefer slightly acidic soil.
- A Windowsill: You can even grow green onions indoors on a sunny windowsill. Use a small pot and ensure the soil is well-drained.
Planting Your Onion Tops
Now it’s time to plant your prepared onion tops:
1. Make a Hole: Use your finger or a small trowel to create a hole in the soil about 1-2 inches deep.
2. Place the Onion Top: Gently place the cut onion top into the hole, ensuring the green leaves are facing upwards.
3. Cover with Soil: Cover the onion top with soil, leaving the green leaves exposed.
4. Water Thoroughly: Water the soil deeply to help the roots establish.
Caring for Your Regrown Green Onions
Once you’ve planted your onion tops, providing them with the right care is essential for healthy growth:
- Water Regularly: Keep the soil consistently moist but not soggy. Water deeply, allowing the excess water to drain.
- Fertilize Occasionally: You can fertilize your green onions with a balanced liquid fertilizer every few weeks, especially if you’re growing them in a pot.
- Thin Out: If your green onions start to grow too close together, thin them out by removing some of the plants. This will allow the remaining onions to receive more sunlight and nutrients.
- Harvest: You can start harvesting your green onions about 2-3 weeks after planting. Cut the green stalks about an inch above the soil line, and they will continue to regrow.
Tips for Success
Here are some additional tips to help you maximize your green onion regrowing success:
- Use Fresh Onions: The fresher the onion, the better the chance of regrowth. Avoid using onions that are wilted or have been stored for a long time.
- Don’t Overwater: Overwatering can lead to root rot, so allow the soil to dry slightly between waterings.
- Provide Adequate Sunlight: Green onions need at least 4-6 hours of sunlight per day.
- Be Patient: It may take a few weeks for your green onions to start regrowing, but with patience and proper care, you’ll be rewarded with fresh, delicious greens.
