Now that you understand the benefits, let’s move on to the step-by-step process.

Step 1: Gather Your Materials

First things first, gather the necessary materials:

• One empty and clean plastic water bottle (preferably with a wide opening)
• Onion bulbs (you can use store-bought onions)
• Sharp knife or scissors
• Water

Step 2: Prepare the Water Bottle

Start by cutting the water bottle in half horizontally. You’ll only need the bottom half for planting, so set the top half aside for recycling. Make sure to rinse the bottom half thoroughly to remove any residue.

Step 3: Prepare the Onion Bulbs

Take your onion bulbs and carefully peel off the outer layers until you expose the roots at the bottom. Trim any excess roots, leaving about half an inch attached to the bulb. This will encourage healthy growth.

Step 4: Plant the Onions

Fill the bottom half of the water bottle with water, ensuring that it’s deep enough to submerge the roots of the onion bulbs. Place the bulbs in the water, root-side down, making sure they are fully submerged. You can plant multiple bulbs in one water bottle, spacing them out evenly.

Step 5: Provide Adequate Care

Place the water bottle in a sunny spot where it can receive plenty of natural light. Change the water every few days to keep it fresh and prevent stagnation. Over time, you’ll notice the roots growing longer and white shoots emerging from the top of the bulbs. This is a sign that your onions are thriving!

Step 6: Harvest Your Onions

As your onions continue to grow, you can harvest them at any stage depending on your preference. For green onions, you can start harvesting when the shoots reach a desirable height. If you prefer fully mature onions, allow them to grow until the bulbs are large and firm.

Step 7: Enjoy Your Homegrown Onions!

Once harvested, rinse your onions thoroughly and use them in your favorite recipes. There’s nothing quite like the satisfaction of cooking with homegrown produce!
