The healthiest and simplest crops to cultivate at home is the green onion, often known as scallions.
When consumed, their nutrient density provides nourishment for our bodies. Growing green onions from leftovers is a widespread activity that also helps cut down on food waste.
Growing food from soil and water is possible if you choose to regrow green onions. Keep in mind that it doesn’t matter what size or shape of green onion you use; the process stays the same unless you forget to cut off the root end.
Growing green onions from scraps
Two of the most common methods for fast re-growing green onions from cuttings are provided below.
You have the freedom to choose whichever option suits you best. So, let’s get right in and get started.
Regrow green onions in water
You’ll need a few things before we go into the detailed instructions for growing green onions in water. It includes the following:
- No damage to the crop’s roots
- The crop’s white bulbous part, measuring one to two inches in length
- A window or other indoor light source
- One cup of water
Steps
- To get started, peel and chop the onions. Don’t remove the white bulbs and roots from the plant; you’ll need them later.
- Rinse the white stalks in running water to remove any dirt that may have accumulated.
- Pick a small cup, set it on a flat surface, and fill it with water. The bulb is visible from above if there is enough room in the water. Carefully insert the bulbs into the jar.
- The next step is to find a window where your plant will receive the most light. Put the glass jar there, next to the window.
- The plant will grow while you wait. You should dump the water in the glass container every two to three days and start fresh. When the water becomes cloudy or discolored, throw it out and start fresh.
- The work is completed! Keep in mind that it will be at least a day before you see any change in the onions.
Regrow green onions in the soil
- The first thing you need to do when re-growing these plants is to let them grow to a height of about five inches. This will allow them to absorb more nutrients from the soil. Or, wait a week and regrow them in soil.
- One of the advantages of re-growing the onions in the soil is that you can use them to grow green onion scrap. It may take up to a month longer than usual, though. Follow this procedure.
- Cleaning the green onions is the first thing. Carefully remove them from the container they’ve been in for so long. Then place them in a sink or other location with running water. To ensure a clean green onion harvest, rinse them thoroughly to remove debris.
- Choose a pot, preferably one with drainage holes and made of porous material. You should get bagged soil, which only retains water for a short time. It’s up to you whether you sprinkle the soil before or after you sow the selected seeds or cuttings. Keep the soil consistently moist, though. Making the soil wet beforehand would only help because it would make it more stable.
- To plant green onions, make holes in the soil using a poker or your fingers. Don’t make holes too big; the plant can lose its capacity to stand up straight. In addition, there should be around 1.5 inches of space between each soil hole.
- Planting the onions is the next stage. Plant a green onion by inserting its roots into a hole and covering them with soil. Green onion bulbs should be buried about 2 inches deep in tightly packed soil to prevent plants from leaning over. The size of the container determines how many green onions you can plant within it. Don’t cram too many plants into the container, or they won’t get enough light.
- The very last thing you need to do is begin watering the pot. Be prepared to have your patience severely tested by this procedure. Maintaining soil that is neither too wet nor too soggy is all you need. Take note of the soil’s structure. Do not allow it to dry out too much.
How Long Does It Take to Grow Onions From Scraps?
Getting a sprouting piece of onion to grow into a full-fledged onion can take some time and patience. If you plant an onion seedling on a sunny windowsill, it will take 90 to 120 days until the onion is ready to be picked.
When sprouting onion greens, the time to harvest is drastically reduced to just a few weeks. Growing scallions from seed to harvest might take as little as six weeks.
Green onions can be re-rooted in water or soil and grown from there several times. You can do this up to five times before you run out of energy, and any growth that could develop is too feeble to survive.
How to Take Care of Green Onions
No special attention is needed for your newly regrown green onions. Your onions should thrive if you keep the water clean and algae-free by changing it often.
If your tap water is highly chlorinated, it is best to let it rest at room temperature overnight before consuming it. Tap water works typically fine, but if you want, you can use filtered or bottled water.
If you have multiple green onions and harvest only one leaf at a time, you can keep picking greens for a few months this way.
The bulb will continue to weaken over time because photosynthesis can only partially meet a plant’s nutritional needs. Planting onions in the soil allows for a longer growing period, typically three to four months.
Steps to Transferring Green Onions from Water to Soil
Carefully plant soil around one green onion stalk in the hole. Use the other stalks in the same manner.
Allow the roots about an inch (2.5 cm) of space between each stem. Soil should be pressed tightly around the stalks, and the planter should be filled to the top.
Taking care of green onions
Green onions are the most adaptable plants since they thrive in a wide range of conditions. The goal is not only survival but also flourishing. Thus, there are certain measures you can take to ensure their success in your backyard.
