Can You Compost Garlic? Unraveling the Mystery


Welcome to our comprehensive guide on the compostability of garlic! If you've been wondering whether it's safe to put garlic in your compost bin, you're not alone. In this article, we will explore the complexities surrounding this topic and provide you with all the information you need to make an informed decision.

Understanding the Composting Process

Before we delve into the specifics of composting garlic, let's first understand the composting process itself. Composting is a natural decomposition process where organic materials break down into nutrient-rich soil. This process is vital for reducing waste, enriching soil fertility, and promoting a sustainable ecosystem.

The Case of Garlic: Can It Be Composted?

Now, let's address the burning question - can you compost garlic? answer is a resounding yes! Garlic can indeed be composted. However, there are certain factors to consider before tossing it into your compost bin.

Decomposition Timeline: How Long Does Garlic Take to Compost?

Garlic is considered a relatively quick decomposer, with a decomposition timeline ranging from 2 to 3 months. This means that, under ideal conditions, garlic scraps will break down completely within this timeframe.

Carbon-to-Nitrogen Ratio: Finding the Right Balance

To ensure successful composting, it's crucial to maintain a proper carbon-to-nitrogen (C:N) ratio. Garlic has a C:N ratio of approximately 15:1, which classifies it as a material rich in nitrogen. This makes it an excellent addition to foster the decomposition process in your compost pile.

Vermicomposting: A Word of Caution

While garlic can be composted in traditional composting systems, such as open-air compost bins, it's advisable to exclude it from vermicomposting. Vermicomposting involves the use of worms to break down organic matter. Garlic, with its pungent aroma, may discourage worms from thriving in your vermicomposting setup.

Alternative Uses for Garlic Scraps

If you decide not to compost your garlic scraps, don't worry! There are other eco-friendly ways to put them to good use. One option is to create a nutrient-rich garlic-infused liquid fertilizer by steeping the scraps in water for a few days. This homemade fertilizer can then be diluted and applied to your plants for a natural boost.


In conclusion, garlic can be safely composted in traditional systems, but it's best to omit it from vermicomposting setups. By understanding the decomposition timeline and maintaining a proper C:N ratio, you can successfully incorporate garlic scraps into your compost pile, contributing to a healthier environment. Remember, composting is a journey of trial and error, so embrace the process and happy composting!
