As the onions continue to develop, Dr. Obi explains a critical step: once the cluster of onions grows sufficiently, they should be pulled up and transplanted again to allow each shoot, now a seedling, to grow independently. Each seedling, properly separated with roots intact, can be planted again. If separation proves challenging, simply return the entire cluster to the soil to allow further growth before attempting to transplant.

How to Grow Onions from Kitchen Scraps: A Step-by-Step Guide
The idea of growing fresh vegetables at home might sound daunting, but Dr. Obi’s recent video reveals that it can be as simple as reusing your kitchen scraps. In particular, Dr. Obi teaches viewers how to effectively grow onions from just one onion bottom, a technique that promises endless access to this essential kitchen ingredient without ever needing to make another onion purchase.
The Initial Steps: Preparing the Onion Bottom
Part 2/8:
To start this process, Dr. Obi recommends cutting the bottom one-third of an onion bulb. This portion will serve as the foundation for your new onion plants, while the remaining two-thirds can be utilized in cooking. After you’ve sliced the onion, remove the papery outer layers and trim any dried-up roots to prepare your planting material.
Setting Up the Growing Environment
Next, Dr. Obi demonstrates how to set up a simple growing container. You can use a plastic bottle with the top section cut off, or a glass cup. Fill it almost to the brim with clean water, making sure to place the onion bottom in such a way that the cut end is submerged in the water. If the onion piece is small, toothpicks can be inserted strategically to keep it above the water’s surface.
Monitoring Growth
Part 3/8:
In just two days, you can expect to see new roots and shoots emerging from the onion bottom. By the ninth day, the growth will be even more pronounced, making it clear that the onion is ready for the next phase. However, it's essential to keep an eye on the onion; if it’s too small or the container is too large, the piece might fall into the water and die, as highlighted by Dr. Obi's experiences.
Transplanting into Soil
Once the onion bottom has developed visible growth, it’s time to transfer it into soil. Dr. Obi emphasizes that the soil should be well-draining and filled to a height of at least six inches. Create a hole deep enough to accommodate the roots and part of the onion bottom and gently cover it with soil. It’s crucial not to plant too deeply, as that can lead to plant death.

Caring for the Onions
After transplanting, ensure the young plants receive adequate sunlight and moisture. With proper care, you can expect to see significant growth—by day 40, the shoots will flourish, as demonstrated by Dr. Obi comparing transplants from onion bottoms to those planted from full bulbs. He notes that while the full bulbs initially grow larger and faster, the onion bottoms still yield a satisfying harvest.
Harvest Time: Separating and Replanting Seedlings
Part 6/8:
Dr. Obi shares his personal gardening experience by planting one set of seedlings in the ground among his pineapples while others are grown in containers. This strategic planting maximizes space and increases yield. Although seedlings without roots can still be planted, they will take longer to mature compared to their rooted counterparts, which do produce slight differences in bulb size and growth rates.
Final Stages: From Seedling to Maturity
Part 7/8:
After 90 days, some seedlings that previously struggled to separate can be put into containers. Allowing these seedlings to mature leads to another critical observation as they reach the 120-day mark. At this stage in their development, viewers learn to recognize signs of maturity, particularly when the leaves topple over, signaling it's time to harvest.
Harvesting the Onions
Once mature, onions can be harvested immediately or dried down for later use. Dr. Obi also points out that it can take another 30 days for additional bulbs to mature, bringing forth more opportunities for a bountiful harvest. As he showcases the results, it’s revealed that he harvested a total of 21 bulbs from just that initial single onion bottom.
Conclusion: A Sustainable Gardening Method
Part 8/8:
Dr. Obi’s detailed tutorial inspires viewers to embrace this sustainable gardening method that directly utilizes kitchen scraps. The process not only fosters self-sufficiency but also demonstrates the rewarding cycle of planting and harvesting. With proper care and attention, anyone can replicate this success in their own backyard or kitchen garden, ensuring a continual supply of fresh onions.
