Do you often buy green scallions, forget them in the fridge, and find them wilted days later? We've been there too. But here's some good news—what if we told you that we can grow our own fresh scallions at home using just regular onions?


Yes, it's easy, fun, and saves money! Let's walk through how we can turn leftover onion bulbs into beautiful, fragrant green scallion plants—perfect for cooking or decorating our kitchen windowsill.


What You Need to Get Started?


To grow scallions from onions, we don't need a fancy garden or expensive tools. All we need are:


• 1 or more small onions (white, yellow, or red—all work!)


• A shallow bowl or small pot


• Clean water


• Potting soil (optional)


• A sunny windowsill or balcony


If we've got leftover onions that started sprouting in the kitchen drawer—don't toss them! They're actually perfect for this.


Method 1: Grow in Water


The simplest way to start is using water. Here's how:


1. Peel the outer skin off the onion but keep the base and roots intact.


2. Place the onion in a small bowl with just enough water to cover the bottom (about 1 cm deep).


3. Set the bowl in a sunny spot—like near a kitchen window.


4. Change the water every 1–2 days to keep it fresh and avoid bad smells.


5. In 3–5 days, you'll see green shoots coming out from the top!


Within a week or two, the shoots will grow tall and look just like green scallions. Once they reach 10–15 cm, we can trim and use them in our dishes!


Method 2: Plant in Soil


Want stronger and longer-lasting scallions? Try planting the onion base in soil. Here's the step-by-step:


1. Cut off the top two-thirds of the onion, keeping the root end.


2. Let the bottom dry for a few hours to reduce the chance of rotting.


3. Fill a small pot with loose potting soil and make a shallow hole.


4. Place the root end in the hole with the cut side up, and cover lightly with soil.


5. Water gently and place in a sunny area.


With good sunlight and occasional watering, the green shoots will grow steadily. This method allows us to harvest several times—just cut the greens and let them regrow!


How to Care for Your Green Scallions?


Here are some easy care tips:


• Sunlight: Aim for at least 4–6 hours of light per day.


• Watering: Keep the soil moist but not soggy. If growing in water, always keep the water clean.


• Trimming: Use kitchen scissors to cut the green part when it's tall enough. Don't cut all the way to the bottom—leave 2–3 cm to help it grow back.


• Replant if Needed: After a few harvests, the onion base might get tired. Simply start over with a new bulb.


Why We Love This Trick?


Growing scallions from onions is more than just a fun home project. It's:


• Budget-friendly: Save on groceries with every regrown bunch.


• Eco-friendly: Reduce kitchen waste by reusing food scraps.


• Satisfying: Watching something grow from almost nothing is such a great feeling.


• Handy: Fresh scallions are always just a few steps away!


Plus, scallions are super useful. We can toss them in noodles, soups, omelets, or sprinkle them on rice—instant flavor boost.


Try It with Kids or Friends


This little planting experiment is also perfect for sharing with children or roommates. It's quick, clean, and fun to watch. You can even decorate the pot or glass to make your windowsill look livelier.


If you've never planted anything before, this is a great way to start. It's hard to mess up and gives results fast—great for beginners!
