Types of soil on the market
Screened topsoil is a process where the soil is filtered through a mesh (picture a very large sieve!) in order to remove stones and debris from the soil. Customers can choose how fine or chunky they want the topsoil to be depending on what it will be used for. For example, a screened ton of topsoil sold as screened to 10mm means there will be no stones or debris in the soil over 10mm (1cm) in diameter. The benefit of screened topsoil is that it is a consistent size which allows for optimum water flow and distribution of essential nutrients which will keep your garden healthy.
Unscreened topsoil does not go through the meshing process so it tends to be coarser and more uneven. It is therefore a cheaper alternative and as can be expected doesn’t provide the same quality and benefits as the screened topsoil does.
