Living in a small apartment with limited outdoor space doesn’t mean you have to give up on composting. Whether you’re an avid gardener or simply want to minimize your waste, composting on a small balcony is not only possible, but also highly beneficial. In this article, we will explore the best practices for composting in a small balcony space, providing you with easy and effective methods to turn your food scraps into nutrient-rich soil. So, grab your gardening gloves and let’s get composting!

Choosing the right composting method

When it comes to composting in a small balcony space, there are several methods to choose from. Each method has its own advantages and considerations, so it’s important to select the one that suits your specific needs.


Vermicomposting, also known as worm composting, is an excellent option for small spaces. It involves using worms to break down organic waste into nutrient-rich compost. With vermicomposting, you can create compost indoors or outdoors, making it a versatile choice for apartment dwellers. The worms consume the organic matter and produce castings that are rich in nutrients. This method is great for those who want a hands-on approach to composting and want to have control over the process.

Bokashi composting

Bokashi composting is another suitable method for small balcony spaces. It relies on the fermentation of organic waste with the help of beneficial microorganisms. Bokashi bins are airtight containers that allow the waste to ferment without producing any foul odors. This method is convenient because it accepts a wide range of food scraps, including meat and dairy products, that may not be suitable for other composting methods. Additionally, bokashi composting is relatively fast, taking about two weeks to complete.

Tumbling composters

If you have a bit more space on your balcony, you may consider using a tumbling composter. These composters are designed to be rotated, which helps speed up the composting process. Tumbling composters are particularly efficient because they allow for proper aeration and mixing of the compost materials. They are also elevated off the ground, making them a great option for keeping pests away. However, it’s important to note that tumbling composters may not be suitable for small balconies due to their larger size.

Compost bins

Compost bins are a classic and versatile choice for composting in small balcony spaces. These bins come in various sizes and materials, allowing you to find the perfect fit for your balcony. When selecting a compost bin, consider the dimensions of your space and the amount of organic waste you generate. There are many space-saving options available, such as compact vertical bins or collapsible bins that can be easily stored when not in use. Compost bins offer a straightforward method of composting and are suitable for beginners and experienced composters alike.

Selecting the appropriate composting container

Once you have chosen the composting method that works best for your small balcony space, it’s time to select the appropriate composting container. The container you choose should be able to accommodate the composting method you have selected and fit within the space available on your balcony.

Size considerations

When selecting a composting container, it’s crucial to consider the size of your balcony and the amount of compostable materials you generate. If you have limited space, opt for compact containers that can easily fit in a corner or against a wall. On the other hand, if you have a larger balcony, you can choose bigger composting containers that allow for more composting capacity. Additionally, consider the height of the container, as taller containers may be more challenging to access and turn the compost.

Material options

Composting containers are available in various materials, each with its own benefits and considerations. Some common options include plastic, metal, and wood. Plastic containers are lightweight, durable, and often come with ventilation options. They are also relatively affordable and low-maintenance. Metal containers, such as stainless steel or galvanized steel, offer excellent durability and resistance to rodents and other pests. Wood containers have a natural aesthetic appeal and can blend well with outdoor environments. However, they may require more maintenance and may not last as long as plastic or metal containers.

Multiple-container systems

In some cases, a single composting container may not provide enough space for your composting needs. In such situations, you can consider using multiple-container systems. This approach involves having different containers for different stages of the composting process. For example, you may have one container for adding fresh compostable materials, another container for the active composting phase, and a third container for curing the finished compost. Multiple-container systems provide more flexibility and allow for better organization of the composting process.

Managing the composting process

Once you have set up your chosen composting method and container, it’s important to actively manage the composting process to ensure successful decomposition and minimize any issues that may arise.

Balancing the carbon-to-nitrogen ratio

One of the key factors in successful composting is maintaining a balanced carbon-to-nitrogen (C:N) ratio. The ideal C:N ratio for composting is generally considered to be around 30:1, although this can vary depending on the materials being composted. Carbon-rich materials, such as dry leaves, straw, or cardboard, provide energy to the microorganisms and help create a stable structure in the compost. Nitrogen-rich materials, such as kitchen scraps, grass clippings, or coffee grounds, provide the necessary nutrients for the microorganisms to thrive. Achieving the right balance between carbon and nitrogen materials is essential for efficient composting.

Adding the right ingredients

To maintain a healthy compost pile, it’s important to add the right ingredients. In addition to the carbon and nitrogen materials mentioned earlier, you can also add other organic materials such as eggshells, coffee filters, and shredded newspaper. It’s recommended to avoid adding meat, dairy products, or oily foods, as they can attract pests and produce unpleasant odors. It’s also a good idea to chop or shred larger materials into smaller pieces, as this helps speed up the composting process. Remember to layer the different materials in the compost pile, alternating between carbon-rich and nitrogen-rich materials.

Turning and aerating the compost

Regularly turning and aerating the compost is crucial for providing oxygen to the microorganisms and preventing the accumulation of anaerobic conditions that can lead to foul odors. Turning the compost involves mixing the materials in the pile, ensuring that they are evenly distributed and allowing for better airflow. This can be done by using a pitchfork or shovel to manually turn the compost or using a tumbling composter that allows for easy rotation. Aim to turn the compost every few weeks or whenever it starts to cool down or become compacted.

Monitoring moisture levels

Proper moisture levels are essential for the composting process. The compost pile should have the consistency of a damp sponge, with enough moisture to provide a suitable environment for the microorganisms, but not so much that it becomes soggy or waterlogged. In general, aim for a moisture level between 40% to 60%. You can monitor the moisture by squeezing a handful of compost – if a few drops of water are released, the moisture is just right. If it’s too dry, add water; if it’s too wet, add dry carbon-rich materials, such as shredded newspaper or dry leaves.

Troubleshooting common issues

Composting may sometimes encounter challenges, but with proper troubleshooting, you can overcome them. One common issue is a compost pile that has a foul odor. This can be a result of anaerobic conditions caused by lack of oxygen or too much moisture. To resolve this, turn the compost more frequently to increase airflow or adjust the moisture levels by adding dry materials. If the compost pile is not heating up or decomposing properly, it may lack nitrogen or moisture. Consider adding nitrogen-rich materials or watering the compost pile, respectively. Additionally, if pests are attracted to your compost, try burying or covering the food scraps under a layer of carbon-rich materials to make them less accessible.

Dealing with limited space challenges

Composting in a small balcony space may pose some challenges, but there are several strategies you can employ to maximize your composting potential.

Vertical composting systems

One effective way to make the most of limited space is by using vertical composting systems. These systems utilize tiered containers or stackable bins that allow you to compost upward rather than outward. By stacking the composting containers vertically, you can take advantage of unused vertical space on your balcony. Vertical composting systems are particularly beneficial for balconies with little floor space. They provide a compact and efficient way to compost and are often designed with features that promote proper aeration, drainage, and composting processes.

Utilizing hanging baskets

Hanging baskets are not just for flowers and plants. They can also be a creative and space-saving solution for composting on a small balcony. By suspending a compost bin or a vermicomposting system from a sturdy hook or railing, you can take advantage of vertical space without sacrificing valuable floor or surface area. Hanging baskets allow for easy access and can be visually appealing, especially if you choose stylish or decorative options. Just ensure that the hanging baskets are securely fastened to prevent accidents and spills.

Composting with sub-irrigated planters

Sub-irrigated planters, also known as self-watering containers, can serve a dual purpose by allowing you to compost while growing plants. These planters have a reservoir at the bottom that provides water to the plants, and the excess water collects in a separate compartment. By diverting the excess water into a composting chamber or bin, you can effectively compost while minimizing space requirements. Sub-irrigated planters are available in various sizes and styles, making them suitable for balconies of all sizes. Plus, they create a visually pleasing and productive green space on your balcony.

Composting in an apartment setting

Living in an apartment doesn’t mean you can’t compost. With the right techniques and considerations, you can successfully compost even in an enclosed space.

Odor control measures

One common concern with composting in apartments is the potential for foul odors. However, with proper odor control measures, you can minimize or eliminate any unpleasant smells. Firstly, ensure that your composting container is airtight or has a tight-fitting lid to prevent odors from escaping. Bokashi composting, which relies on fermentation in an airtight container, is particularly effective at minimizing odors. Additionally, avoid adding meat, dairy, or oily foods to your compost, as these are more likely to emit strong odors. Finally, periodically clean and rinse your composting container to prevent buildup or lingering smells.

Composting in enclosed spaces

If you have limited outdoor space on your balcony or no outdoor space at all, you can still compost indoors. Vermicomposting is a popular choice for indoor composting, as it is odorless and compact. You can keep a worm bin under your kitchen sink or in a closet, provided there is proper ventilation and temperature control. Bokashi composting is another indoor-friendly method, as the airtight container prevents odors from escaping. Whichever method you choose, ensure that you have a designated space for composting and take care to maintain appropriate conditions for the compost to thrive.

Using compost for indoor plants

One of the benefits of composting in an apartment setting is the opportunity to use the compost for your indoor plants. Compost is a nutrient-rich soil amendment that provides plants with essential nutrients and improves soil structure. Once your compost is ready, you can mix it with potting soil to create a nutrient-rich blend for your indoor plants. This will help support healthy growth and minimize the need for synthetic fertilizers. Just be sure to let the compost cure as needed to ensure it is fully decomposed and won’t introduce any potential pathogens or pests to your indoor garden.

Harvesting and using the compost

After weeks or months of composting, it’s time to reap the benefits of your efforts. Here’s how to know when your compost is ready, how to harvest it, and ways to use it in your balcony garden.

Knowing when compost is ready

Compost is ready to use when it is dark, crumbly, and has a pleasant earthy smell. It should resemble rich soil and be free of recognizable food scraps or organic materials. The length of time it takes for compost to be ready can vary depending on factors such as the composting method, temperature, and the materials used. In general, vermicompost can be ready in as little as two months, while traditional composting may take six months to a year. It’s a good practice to periodically check the readiness of your compost by doing a visual and smell test. If it meets the desired characteristics, it is ready to be harvested.

Harvesting compost

To harvest compost, start by stopping any additions of fresh organic matter a few weeks before you plan to harvest. This allows the remaining materials to finish decomposing. Once you’re ready, there are a few methods you can use to separate the compost from any remaining uncomposted materials. One simple technique is to sift the compost through a screen or mesh, which will allow the fine compost to fall through while retaining any larger materials. Alternatively, you can create composting layers in your compost bin or container. As the compost matures, the bottom layer will be ready for harvesting, and you can simply remove the upper layers and access the finished compost.

Using compost for balcony gardens

Compost is a valuable resource for improving the health and vitality of plants in your balcony garden. It enhances the soil structure, promotes nutrient availability, increases water retention, and encourages beneficial microbial activity. To use compost in your balcony garden, simply mix it into your potting soil or incorporate it into the existing soil in your raised beds or planters. Aim to use compost at a ratio of about 20 to 30% of the total soil volume. This will provide an ideal balance of nutrients without overwhelming the plants. As you water your garden, the compost will gradually release its nutrients, feeding your plants and promoting their overall well-being.
