Maximizing Kitchen Scraps: A Guide to Regrowing Onions, Leeks, and Green Onions

In today’s guide, we’ll explore an innovative way to make the most out of kitchen scraps by regrowing onions, leeks, and green onions. Rather than discarding these scraps, we can transform them into thriving plants that not only add freshness to our meals but also reduce waste.

**Understanding What to Regrow:**

Before we delve into the regrowing process, it’s essential to identify the suitable parts of the kitchen scraps for regrowth. For leeks and green onions, the presence of roots is crucial. It’s important to distinguish between the basal stem and the leaf base. We should opt for scraps with a visible portion of the basal stem, ensuring successful regrowth.

**Preparing the Scraps:**

Once we’ve identified the suitable scraps, we can proceed with cutting them for regrowth. For leeks and green onions, a cut of approximately 5 centimeters from the base is recommended. This ensures that we have enough stem for regrowth while leaving room for new shoots to emerge.

**Optimizing Regrowth:**

The beauty of regrowing kitchen scraps lies in the abundance it offers. After two or three harvests, the remaining plants can be transferred to the garden to continue their growth cycle. In the case of onions, new bulbs or seeds will start to emerge, providing us with a continuous supply of fresh produce.

**Choosing the Right Scraps:**

Selecting scraps with a wider base ensures a higher yield of new plants. By opting for scraps with ample basal stem, we can maximize the number of plants regenerated, ensuring a bountiful harvest.

**Regrowing Process:**

To initiate the regrowth process, we bury the scraps in a suitable medium, such as soil or compost. The depth should be sufficient to cover the scraps, leaving the top exposed. It’s important to water the scraps regularly, ensuring adequate moisture for optimal growth.

**Harvesting and Maintenance:**

As the plants grow, we can harvest the leaves as needed, allowing the remaining scraps to continue regrowing. Regular watering and monitoring of humidity levels are essential for sustained growth. By harvesting in sectors, we provide ample time for new leaves to regenerate, ensuring a continuous supply of fresh produce.


Regrowing kitchen scraps offers a sustainable solution to reducing waste while providing a fresh source of ingredients for our meals. By following these steps, we can transform discarded scraps into thriving plants, enriching our culinary experience and contributing to a greener environment. Let’s embrace this eco-friendly practice and share the knowledge with others, ensuring that everyone can benefit from the abundance of nature’s resilience.
