Topsoil prices will differ dramatically based on region, quality and a number of other factors. However, a reasonable price in most regions is under £13 per cubic yard. Good topsoil appears brown in colour and will crumble between your fingers when you hold it; quality topsoil can prevent weeds and other unpleasant surprises in a yard.
Why Use Topsoil
Topsoil refers to the top six or so inches of a yard or garden, which holds the large majority of nutrients that plants and trees need for optimum health. Topsoil also includes composted material and can be the cause of many garden problems. Topsoil is needed for new yards, for gardens and can be used to help "level" an uneven lawn.
Topsoil is most frequently sold in cubic yards. The thickness you spread topsoil depends on the use (e.g., new lawn vs. garden, etc.). However, a cubic yard spread an inch thick will cover about 324 feet. Multiply the length of your surface by its width to determine the area you need to cover, and then compute the yardage needed from there.
Cost per Yard
According to CostHelper.com, cost depends on your location within the country, whether the soil is delivered or picked up and the quality of the soil. You can generally buy topsoil for £7 to £11 for a cubic yard. High-quality topsoil may cost up to £19 in the more expensive markets; however, more than £19 may be overly expensive. The more you order, the less it will cost per yard. Delivery will depend on weight and distance, and a rate should be agreed on upfront.
Cost per Bag
Topsoil also comes in bags and costs anywhere from £1.30 to £3 per bag. Nearly 20 bags are needed to create a cubic yard. So, at a rate of £117 to £325 per cubic yard, bags should only be used for small areas.
Soil quality can differ significantly from source to source. A good way to find quality topsoil in quantity is to ask at your local greenhouse or home improvement store for a referral. You may be able to find free topsoil at freedirt.com or by checking with your local town or village. Individuals purchasing soil earlier in the spring may have a wider array of options.
