What You’ll Need to Grow Onions in Water

Step-by-Step Guide to Growing Green Onions in Water

Ready to learn how to grow green onions in water? Follow these simple steps, and you’ll have fresh greens in no time.

Step 1: Prepare Your Onion

Peel off the outer papery skin of your onion. If it’s already sprouting, you’re ahead of the game! Cut off the top (pointy end) of the onion, leaving about 1-2 inches of the bulb with the root end (the hairy bottom) intact. This is where the magic happens.

Step 2: Set Up Your Water Container

Fill your glass or jar with water, but don’t go overboard—just enough to touch the onion’s root end. You’ve got two options

1. Submerge the root end: Place the onion root-side down in the glass, letting it sit at the bottom.
2. Suspend with toothpicks: Poke four toothpicks into the onion’s sides and balance it over the jar so only the roots touch the water. This keeps the bulb from getting too soggy.

Step 3: Find a Sunny Spot

Place your setup on a windowsill or another spot with plenty of indirect sunlight. Onions thrive with at least 6 hours of light daily. If sunlight is scarce, consider a grow light to keep your onions happy.

Step 4: Keep the Water Fresh

To ensure healthy growth, change the water every 2-3 days. Pour out the old water, gently rinse the roots, and refill with fresh water. This prevents mold and keeps your onion thriving.

Step 5: Watch Your Onions Grow

In just a few days, you’ll see white roots sprouting from the bottom and green shoots popping up from the top. Within 1-2 weeks, those shoots will be 4-6 inches long, ready to snip for cooking. It’s like growing your own garnish!

Troubleshooting Common Issues

Sometimes, things don’t go as planned. Here’s how to handle common hiccups when growing onions in water.

• No growth? Ensure the onion is fresh (not too old or soft) and getting enough sunlight.
• Smelly water? Change the water more frequently and ensure only the roots are submerged.
• Mold on the onion? Trim any slimy parts and reduce water contact with the bulb.
