Can You Compost Citrus?

Composting is a vital practice for garden enthusiasts, turning organic waste into nutrient-rich soil that benefits plant growth. A frequent question among composters is whether citrus fruits, with their distinct characteristics, can be successfully integrated into compost. This article addresses this query, exploring the role of citrus in composting and offering guidance for best practices.

Citrus in Composting

Citrus fruits, such as oranges, lemons, and grapefruits, are known for their high acidity and strong, fragrant oils. These attributes have significant implications for the composting process. The acidic nature of citrus can affect the pH balance of the compost, while the oils can contribute to a longer decomposition time compared to other organic materials. However, these factors do not necessarily preclude citrus from being a valuable component of compost. It’s essential to understand how to manage these characteristics to make citrus an effective addition to the compost pile.

Benefits of Adding Citrus to Compost

Incorporating citrus into compost can offer several benefits. Citrus adds organic matter that decomposes over time, releasing nutrients back into the soil. This can enhance the nutrient profile of the compost, providing additional nourishment for plants. Moreover, the distinctive scent of citrus can help in attracting beneficial microorganisms to the compost pile, aiding in the decomposition process. These microorganisms are crucial in breaking down organic matter and transforming it into usable compost. However, it’s important to balance these benefits with the potential challenges that citrus can bring to the composting process.

Concerns with Composting Citrus

While citrus can be a beneficial addition to compost, there are several concerns to consider. One of the primary concerns is the impact of citrus’s high acidity on the compost pile’s pH balance. An overly acidic compost can hinder the activity of beneficial microorganisms and affect the overall health of the compost. Additionally, the strong oils and acidic content in citrus peels can slow down their decomposition, taking longer to break down compared to other organic materials.

Another consideration is the attraction of pests. The strong scent of citrus can sometimes attract fruit flies and other insects, potentially leading to pest issues in or around the compost pile. This is particularly a concern in open composting systems without proper containment or cover.

Best Practices for Composting Citrus

To successfully compost citrus and mitigate potential issues, certain best practices can be followed:

  • Balance with Other Materials: It’s important to balance citrus waste with other compost materials, particularly with “brown” materials like dry leaves, straw, or shredded paper, which can help neutralize acidity and add carbon to the compost.
  • Chop or Shred Citrus Peels: Breaking down citrus peels into smaller pieces can accelerate their decomposition. This can be done by chopping or shredding the peels before adding them to the compost.
  • Monitor Compost Health: Regularly check the compost’s condition, especially when adding citrus. Ensure it maintains a healthy balance and doesn’t become overly wet or acidic.
  • Layering: Layering citrus peels with other compost materials can also aid in faster breakdown and prevent clumping, which can slow the composting process.

By following these practices, citrus can be a valuable addition to compost, contributing to a rich and balanced mix of organic materials.

Composting Large Quantities of Citrus

For individuals or households that have access to large quantities of citrus, such as from a home orchard, composting these amounts requires a bit more consideration. When dealing with a high volume of citrus, it’s crucial to add it to the compost pile gradually rather than all at once. This gradual addition prevents overwhelming the compost with acidity and allows time for microorganisms to effectively break down the material. Mixing or layering the citrus with a substantial amount of brown materials is also essential in these situations. This helps balance the composition of the compost and facilitates a more efficient decomposition process.

Alternatives to Composting Citrus

In cases where composting citrus is not feasible or desired, there are alternative uses for citrus waste. Citrus peels can be repurposed to make a natural, fragrant cleaner by infusing them in vinegar. This creates an effective cleaning solution that is both eco-friendly and economical. Additionally, dried citrus peels can serve as a natural pest repellent in gardens, deterring unwanted insects with their potent aroma. These alternative uses can provide practical and environmentally friendly solutions for utilizing citrus waste.


Composting citrus is indeed possible and can be beneficial for your compost pile, contributing essential nutrients and organic matter. However, it requires careful consideration and management to ensure the health and balance of the compost. By following best practices such as balancing with brown materials, chopping or shredding the peels, and gradually adding large quantities, gardeners can successfully integrate citrus into their composting routine. For those who choose not to compost citrus, alternative uses such as making cleaners or pest repellents offer creative and sustainable ways to utilize this organic waste. Understanding these various aspects allows for a more informed and effective approach to handling citrus in an eco-friendly manner.
