To keep green onions growing, you can try a simple method of placing the bulbs in a jar with water. This is similar to the jar method used in the fridge, but without covering the onions with a bag. Instead, you’ll want to leave the container sitting on a windowsill that receives plenty of natural light. This will provide the onions with the necessary sunlight they need to continue growing.
The first step is to select a jar or container that can hold the green onion bulbs and accommodate enough water to cover their roots. A glass jar works well as it allows you to easily monitor the water level and the growth of the onions. Make sure the jar is clean before adding the water.
Next, carefully place the green onion bulbs into the jar, ensuring the roots are submerged in water. It’s important to maintain a consistent water level to keep the roots covered at all times. You can use tap water for this purpose, but if you have access to filtered water, it may be beneficial for the long-term health of the onions.
Find a sunny windowsill where you can place the jar. Green onions require a minimum of 6-8 hours of sunlight each day to thrive. Ideally, choose a south-facing window or any window that receives ample sunlight throughout the day. If your windowsill doesn’t provide enough light, you can supplement it with artificial grow lights.
Now comes the fun part – watching your green onions grow! With the right conditions, you can expect to see new growth within a week or two. The onions will continue to grow as long as you provide them with the necessary care.
Regularly check the water level in the jar and add more as needed to ensure the roots remain submerged. It’s also a good idea to change the water every 1-2 weeks to prevent any buildup of bacteria or algae. When changing the water, gently rinse the roots with fresh water to keep them clean and healthy.
As the green onions grow, you can harvest them by simply snipping off the green tops as needed. Leave the bulb and some of the green stalk intact to allow for regrowth. This way, you can enjoy fresh green onions for months on end.
It’s worth noting that while this method can keep green onions alive and growing for an extended period, they may not reach the same size as those grown in the soil. However, the convenience of having a continuous supply of fresh green onions right on your windowsill is hard to beat!
In summary, to keep green onions growing in water, place the bulbs in a clean jar, ensuring the roots are submerged. Position the jar on a sunny windowsill, making sure the roots stay covered with water. Change the water every 1-2 weeks, and harvest the green tops as needed while leaving the bulbs intact for regrowth. With proper care, you can enjoy a continuous supply of green onions for months.
