Are you wondering what to do with your old bark mulch? If you’re ready to give your garden a fresh start or simply need to get rid of the old mulch, we’ve got you covered. In this article, we’ll explore several hassle-free methods to help you dispose of your old bark mulch efficiently and responsibly.


Composting is an eco-friendly method of recycling organic materials, such as old bark mulch, into nutrient-rich soil conditioner. It involves a natural decomposition process where microorganisms break down the materials, transforming them into a dark, crumbly substance called compost. Composting not only reduces waste but also enriches the soil, creating a sustainable cycle for your garden.

To compost bark mulch, start by creating a compost bin or pile in a convenient location in your garden. Layer the bark mulch with other organic materials, such as kitchen scraps, leaves, grass clippings, and garden trimmings. Ensure a balance of brown materials (like the bark mulch) and green materials (such as fresh plant matter) to provide the right carbon-to-nitrogen ratio.

Turn the compost regularly to aerate it and facilitate the decomposition process. This helps microorganisms break down the bark mulch and other materials effectively. Maintain a moist but not soggy environment, as excessive moisture can hinder decomposition. Within a few months to a year, depending on various factors like temperature and composition, the bark mulch will transform into nutrient-rich compost that can be used to enhance your garden.

Composting bark mulch offers several benefits. Firstly, it reduces waste by recycling the old mulch instead of sending it to the landfill. This reduces the strain on landfills and minimises the environmental impact. Additionally, the resulting compost is a fantastic soil amendment that enriches the soil with essential nutrients, improves soil structure, and enhances water retention. Composting also helps promote beneficial soil organisms, which aids in the overall health and fertility of your garden.

To ensure successful composting of bark mulch, keep the following tips in mind:

  1. Balance the carbon-to-nitrogen ratio: A good rule of thumb is to aim for a 30:1 carbon-to-nitrogen ratio in your compost pile. This means incorporating a mix of brown materials (like old bark mulch) and green materials (such as fresh plant matter) to maintain the right balance.
  2. Turn the compost pile regularly: Turning the compost every few weeks helps aerate it and promotes decomposition. This ensures even breakdown of the bark mulch and other organic matter.
  3. Maintain moisture levels: Keep the compost pile moist, like a damp sponge, to facilitate the microbial activity. However, avoid over-watering, as it can lead to a soggy pile and slow down decomposition.
  4. Monitor temperature: Composting generates heat as microorganisms break down the organic matter. Aim for a temperature between 110°F (43°C) and 160°F (71°C) to promote optimal decomposition.
  5. Chop or shred larger materials: Breaking down the bark mulch and other organic materials into smaller pieces accelerates the composting process by increasing the surface area available for microbial action.

By following these tips, you can successfully compost your old bark mulch and contribute to a healthier, more sustainable garden ecosystem.
