Fortunately, growing green onions in water is an easy and cost-effective way to enjoy fresh, delicious green onions without breaking the bank. In this article, we will provide a step-by-step guide on how to grow green onions in water.

What You'll Need

Before we get started, here are the materials you'll need:

  • A bundle of green onions
  • A jar or glass
  • A sunny windowsill
  • Clean water

Step 1: Prepare the Green Onions

Start by cutting off the bottom inch of the green onions, where the roots are located. Make sure to use sharp scissors or a knife to prevent damaging the plant. Next, remove any wilted or discolored leaves from the top of the onion. This will allow the plant to focus its energy on growing new roots and shoots.

Step 2: Plant the Green Onions in Water

Fill your jar or glass with clean water, leaving about an inch of space at the top. Place the green onions in the water, root side down. Make sure that the roots are fully submerged in the water, but the leaves are not touching the water surface.

Step 3: Place the Green Onions in a Sunny Location

Put the jar or glass in a sunny location, such as a windowsill. Green onions thrive in bright sunlight, so make sure to keep them in a well-lit area. If your windowsill doesn't receive enough sunlight, consider using a grow light to supplement the natural light.

Step 4: Change the Water Regularly

You should change the water every few days to prevent bacterial growth and ensure that the green onions have access to fresh, oxygenated water. When changing the water, be sure to rinse the roots under running water to remove any debris or algae buildup.

Your green onions should start to grow new shoots within a week or two. Once they reach a height of 6-8 inches, you can harvest them by cutting off the tops and using them in your favorite recipes. Be sure to leave about an inch of the plant above the roots so that the green onions can continue to grow.
