Where to Place Your Compost Bin

Adding a compost bin to any garden is a great way to create a cheap and valuable source of nutritionally-enriched soil. Composting works by breaking down many forms of organic matter through the natural use of microorganisms.

A vital aspect of successful topsoil is compost bin placement. As long as the area beneath a compost bin has been effectively repaired, placement can take place on many different surfaces including concrete and paving. It is even possible to use an indoor compost bin.


Soil provides the ideal location for a compost bin, particularly in areas of partial shade or direct sunlight as warm conditions can speed up the decomposition process.

Placing a compost bin on soil provides microbes and insects with an easier route to decomposable materials. Soil also provides a source of efficient draining and promotes air circulation. These are both vital ingredients to successful composting.

It is always important to place a compost bin in an area where it is easy to add organic matter.

Once you have decided on a location, dig a hole of around 1 inch in depth that is slightly larger than the diameter of your compost bin. Place an oversized piece of wire mesh over the hole so that waste fluids can drain through to the ground then place the bin on top.


If a compost bin is going to be placed on any type of hard, cold surface it is important to lay a bed of paper, twigs and soil so that worms and other beneficial colonies can survive. You will need to introduce worms and other soil-dwelling organisms by hand. Existing compost can be used as an alternative.

This will also provided a point of absorption that will stop slabs becoming heavily stained by the liquids that fall from compost bins.

You may also consider lifting a couple of slabs so that your compost bin can actually sit within a paved area yet still reap the benefits of a soil environment.  This can be made tidy by adding small plants to create a feature.


Although placing a compost bin on decking isn’t highly recommended, it is still possible to do so. Again, the risk of staining an expensive feature is quite probable.

If using decking as a location is a necessity, try to create a raised bed using matching deck boards so that a visual theme is maintained. These deck boards should be liberally coated in decking sealant to prevent seepage then placed over a plastic lining to offer protection to the rest of your decking.

A bed of soil of peat-free compost can now be added and this will provide a further point of absorption. If there are gaps in the decorative decking, consider making a few small holes in the plastic lining so fluids can drain directly through them and onto the existing soil underneath.


Gravel is a particularly easy surface to place a compost bin on. Simply clear away a large enough area of gravel for the bin to sit in and cut through the membrane so that soil-dwelling microbes can get through. Don’t forget to dig out around 1 inch of soil and place down some wire mesh first!


Concrete can be easily used as a location for a compost bin as long as a suitable bed is made beforehand and colonies are introduced. Soil should be placed on a plastic lining to help prevent staining.

Indoor Compost Bins

Indoor compost bins are available for purchase at any reputable garden centre or from a wide range of online sources. These self-contained units are ideal for creating window garden compost in areas of restricted space.
