How to Regrow Onions: StepbyStep Guide for Success
How to Regrow Onions?
To regrow onions, save the onion bottoms from store-bought or garden-grown onions.
Cut the bottoms about half an inch to an inch thick.
Place them root side down in a pot with damp soil, making sure there are drain holes.
Within a few days, roots will start to grow, and in 2-3 weeks, green shoots will appear.
Alternatively, you can start the cut onion bottoms in a shallow tray with damp soil.
Transplant the rooted onion bottoms into larger containers or garden beds for continued growth.
For larger bulb onions, do not trim the onion greens as they provide nourishment to the bulbs.
There are video tutorials and photos available for guidance, and for further tips, you can refer to the guide on planting onions in the fall season.

Did You Know?
1. Onions have been cultivated for over 5,000 years and were highly prized by ancient Egyptians, who even buried them with their pharaohs as a symbol of eternal life.
2. Did you know that onions contain a naturally occurring compound called quercetin? Quercetin has anti-inflammatory properties and has been linked to reducing the risk of certain diseases, such as heart disease and cancer.
3. When regrowing onions from the discarded bulb bottom or scraps, it is important to choose an onion variety that is suitable for propagation. Some varieties, such as hybrid onions, may not produce the desired results.
4. Onions are members of the Allium family, which includes other popular vegetables like garlic, leeks, and shallots. Alliums are known for their distinct flavors and health benefits.
5. The outermost layer of an onion called the “epidermis” contains a higher concentration of flavonoids compared to the inner layers. These flavonoids contribute to the antioxidant properties of onions, making them beneficial for your health.
Don’t Discard Onion Bottoms
When it comes to onions, the old saying holds true: waste not, want not. Many people are unaware that onion bottoms, those discarded remnants left over from cooking, can be used to regrow fresh onions. Whether you’ve just bought onions from the store or grown them in your garden, don’t throw away those onion bottoms just yet. With a little effort and patience, you can give them a second life and enjoy the satisfaction of growing your own onions.

Plant Onions In Spring And Fall
Onions are versatile crops that can be grown in different seasons, depending on your climate. In most regions, they can be planted in both spring and fall. Spring onions are typically planted from late winter to early spring when the soil is workable, while fall onions are planted in late summer for a crop that matures in the cooler months.
Before you start regrowing onions from scraps, consider the planting season that suits your climate and availability of sunlight. This knowledge will help you create the optimal conditions for successful regrowth.
Regrowing Onions From Scraps Is Trickier
Regrowing onions from onion scraps can be a rewarding experience, but it can be a bit trickier compared to regrowing green onions. Green onions have the ability to easily regenerate by placing the root end in water, but regrowing onions to develop bulbs requires a different approach.
To begin, you will need onion bottoms that are about 0.5″ to 1″ thick. It is important to keep the root side intact, as this is where the magic happens. Taking care of the onion scraps is crucial to ensure proper root and shoot growth.
Here are some tips for successful regrowing of onions:
- Choose onion bottoms that are firm and healthy.
- Make clean, even cuts on the onion bottoms to promote optimal growth.
- Use a well-draining potting mix or soil to plant the onions.
- Place the onion bottoms in the soil, root side down, leaving the top exposed.
- Water the soil thoroughly after planting and keep it consistently moist.
- Provide the onions with indirect sunlight to encourage growth.
- Monitor the moisture levels and adjust watering as needed.
- Be patient, as regrowing onions to develop bulbs can take several weeks or even months.
Remember, regrowing onions from scraps requires patience and attention to detail. By following these tips, you can increase your chances of success and enjoy the satisfaction of using kitchen scraps to grow new onions.

Step 1: Cut Onion Bottoms
To initiate the regrowth process, carefully cut the onion bottoms from the onions you wish to regrow. It is important to leave the root side intact, as this is crucial for developing new roots and shoots. Aim to cut the bottoms at a thickness of around 0.5″ to 1″.
- Carefully cut the onion bottoms
- Leave the root side intact
- Aim for a thickness of 0.5″ to 1″
Step 2: Place Onion Bottoms In Damp Soil
Next, to grow onions from bottoms:
- Prepare a pot or shallow tray filled with damp soil.
- Ensure the container has proper drainage holes to prevent waterlogging.
- Place the onion bottoms in the soil with the root side facing down.
- Cover the tops of the onion bottoms with a thin layer of soil, leaving the root portion exposed.
Remember:
- The soil should be kept consistently damp but not overly saturated.
- Overwatering can lead to rot and hinder the regrowth process.
Green Shoots And Root Growth Indicators
Within a few days, you will start to notice the onion scraps develop roots. In approximately 2 to 3 weeks, green shoots will emerge from the top of the onion bottoms. This is a promising sign that the process is progressing as expected.
If you prefer, you can also start the regrowth process by placing the cut onion bottoms in a shallow tray with damp soil. This method has proved successful, with root growth becoming visible after 1 to 2 weeks. To determine if the onion bottoms are ready for transplanting, gently tug on them. If you feel resistance, it means that the roots have developed sufficiently, and they can be safely transplanted to larger containers or directly into your garden beds.
Once transplanted, take care to provide sufficient sunlight and water the plants regularly. The regrown onions will gradually develop, rewarding you with a bountiful crop that you nurtured from kitchen scraps.
This article has provided a step-by-step tutorial on regrowing onions from scraps, highlighting the importance of not discarding onion bottoms. It emphasizes the versatility of planting onions in both spring and fall seasons and outlines the differences between regrowing onions and green onions. Furthermore, detailed instructions were given on cutting onion bottoms and placing them in damp soil, along with indicators of root and green shoot growth.
