5 Tips for Composting in Your Small Urban Garden

Urban gardening is an excellent way to transform unused spaces into green and lush gardens. However, one of the most significant challenges that urban gardeners face is the lack of space for composting. Composting is a natural process that converts organic waste into nutrient-rich soil. In this blog post, we’ll share five tips for composting in your small urban garden.

Choose the right composting method

Composting can be done in various ways, but not all methods are suitable for small urban gardens. The following are some composting methods that work well in small spaces:

Compost Bins

Compost Bins

Compost bins are the most common composting method. They come in various sizes, shapes, and materials. Choose a compost bin that suits your garden’s size and needs. A compost bin with a tight-fitting lid and a sturdy base is ideal for small urban gardens.



Vermicomposting is compost that is made with worms. It is an excellent method for small urban gardens because it doesn’t require a lot of space. Vermicomposting can be done in a worm bin, which is a container filled with bedding material and worms. The worms eat the organic waste, and their waste (called worm castings) is excellent fertilizer for plants.

Trench Composting

Trench Composting

Trench composting is a simple method that involves digging a trench in your garden, filling it with organic waste, and covering it with soil. The organic waste will decompose over time, and the soil will be enriched with nutrients.

Collect Organic Waste

Organic Waste Composting

Collecting organic waste is an essential part of composting. Organic waste includes kitchen scraps, yard waste, and other biodegradable materials. Collecting organic waste in a small urban garden can be challenging, but the following tips can help:

  • Use a kitchen compost bin – A kitchen compost bin is a small container that can be kept on your kitchen counter. It is used to collect kitchen scraps such as fruit and vegetable peels, coffee grounds, and eggshells. A kitchen compost bin with a tight-fitting lid and a handle is ideal for small urban gardens.
  • Use a compostable bag – compostable bags are made from plant-based materials and can be used to collect organic waste. Compostable bags can be used to line a kitchen compost bin or to collect yard waste.
  • Use a compost service – If you don’t have space to compost in your small urban garden, you can use a compost service. Compost services collect organic waste and turn it into compost for a fee.

Maintain the right composting conditions

Composting requires the right conditions to work correctly. The following are the essential composting conditions:

  • Carbon-to-nitrogen ratio – Composting requires a balance of carbon-rich and nitrogen-rich materials. Carbon-rich materials include dry leaves, straw, and paper, while nitrogen-rich materials include kitchen scraps and grass clippings. The ideal carbon-to-nitrogen ratio is 30:1.
  • Moisture – Compost requires moisture to work correctly. The ideal moisture level is 50–60%. If your compost is too dry, add water. If it’s too wet, add dry materials.
  • Oxygen – Compost requires oxygen to decompose organic waste. Make sure to mix your compost regularly to aerate it.
  • Use compost as a soil amendment – Compost is a nutrient-rich soil amendment that can be used to improve the health of your plants. Here’s how to use compost in your small urban garden:
  • Mix compost into the soil before planting. Compost will improve the soil’s structure and add nutrients.
  • Use compost as mulch: Use compost as a mulch around your plants. Compost will retain moisture and prevent weeds from growing.


Composting in your small urban garden is an excellent way to recycle organic waste and improve the health of your plants. By choosing the right composting method, collecting organic waste, maintaining the right composting conditions, and using compost as a soil amendment, you can turn your small urban garden into a green oasis. With these five tips, you can start composting in your small urban garden and create nutrient-rich soil for your plants. Not only will you be reducing your carbon footprint, but you’ll also be creating a sustainable and healthy garden. So, go ahead and give composting a try in your small urban garden and enjoy the benefits it brings.
