Growing Green Onions from Store-Bought Roots: A Simple Guide

Do you often find yourself reaching for store-bought green onions at the grocery store? Did you know that these very same roots can be used to grow fresh green onions right in your own home? In this guide, we will walk you through the process of regrowing green onions from the roots you buy at the grocery store.

Select Fresh Green Onions

When choosing green onions, opt for those with healthy roots and vibrant green tops. Freshness is key for successful regrowth, so always check the product date and select ones that look plump and firm.

Prepare the Onions

Trim the green tops to about 2-3 inches, leaving the roots intact. This will give you the best chance of regrowth.

Wash the roots thoroughly to remove any dirt and debris.

Water Method

Place the roots in a glass or jar with enough water to cover the roots but not the green part. Make sure the container is clean and wide enough to accommodate the roots comfortably.

Set the jar on a sunny windowsill where it can get plenty of light. Sunlight is crucial for photosynthesis, which helps the roots to regrow.

Change the water every few days to keep it fresh and avoid any water mold growth.

Soil Method

Alternatively, you can plant the roots directly in soil. Use a pot with good drainage and fill it with potting soil.

Plant the roots about an inch deep, ensuring that the green tops remain above the soil surface. This will provide the necessary light and oxygen for growth.

Care for Your Green Onions

If using soil, keep the soil moist but not waterlogged. Overwatering can lead to root rot and hinder growth.

Ensure your green onions get plenty of sunlight. A sunny windowsill or a spot near a sunny window will work well.

Harvest Your Green Onions

You can snip off the green tops as needed, and they will continue to grow back. In just a week or so, you should start seeing new growth. Harvesting regularly will encourage continued regrowth.

This method is a great way to have fresh green onions on hand while reducing waste and saving money. Plus, it's a fun project for the whole family to enjoy!

Repeat the Process

Unfortunately, you won't be able to regrow green onions indefinitely from the same roots. Typically, you can repeat this process about 4 times before the bulb's reserves are depleted. At that point, toss the used roots in the compost bin to add nutrients to your garden soil.

Additional Tips

Did you know that some plants can regrow from seemingly hopeless scraps? For example, you can regrow pineapple from the head after eating one, though green onions are more commonly used. This 'life hack' style idea is both practical and fun!

Happy growing!
