Rolawn Compost Soil Improver is a natural, peat-free compost/soil conditioner/improver made from composted organic matter. It is highly fertile and will improve the structure of clay, sandy or chalky soils by increasing the organic matter content. Improving the soil’s structure will enhance its drainage characteristics and air and water-holding capabilities, all of which will result in healthier plant growth.

How to Use Compost Soil Improver

Rolawn Compost Soil Improver can be used in a variety of ways, from improving topsoil quality to acting as a mulch for added protection and moisture retention. While it’s suitable for potting on, it is not recommended for seed sowing.

Typical application rates for improving topsoils with low levels of organic matter:

  • Heavy clay soil – a layer, 75mm deep, should be incorporated to a depth of 200mm
  • Chalky soil – a layer, 50mm deep, should be incorporated to a depth of 200mm
  • Light sandy soil – a layer, 30mm deep, should be incorporated to a depth of 200mm

For best results, apply soil improver anytime throughout the year, but avoid working with wet soil as this may damage the structure.

Whether you’re improving topsoil for flower beds or borders, or topsoil for vegetable patches, Rolawn Compost Soil Improver provides the natural nourishment and structure your soil needs to thrive.

Important update: Temporary 6.5% surcharge effective 7 April 

At Rolawn, we are committed to maintaining the high standards of quality and service our customers expect, so we want to be open with our customers about a change that will affect pricing from Tuesday 7th April. 

This decision has been taken in response to disruption to energy supplies, which has led to significant increases in wholesale prices, affecting not only fuel and fertiliser but also costs throughout our wider supply chain. As a business that relies heavily on fuel for both transport and operations, these sustained cost pressures have become increasingly difficult to absorb.  

While we have worked hard to mitigate the impact, the scale and pace of recent price increases have now exceeded what we can sustain internally, and we therefore need to recover a proportion of these externally driven increases. 

From Tuesday 7th April, a temporary 6.5% surcharge will apply to all products.  

We know that any increase in price is frustrating, particularly at a time when many businesses and households are already feeling under pressure. That is why we want to be clear that this is not a decision we have made lightly, and not one we wanted to make. It has been introduced solely to help offset unavoidable cost inflation and allow us to continue delivering the quality, reliability and service standards associated with Rolawn. 

We will continue to monitor market conditions closely and will review this surcharge as soon as circumstances allow, providing reasonable notice of any changes. We recognise that any price increase is unwelcome, but this step is necessary to ensure the continuity and reliability of our operations during a period of ongoing uncertainty. 

We remain committed to providing the quality, reliability and service standards you expect from Rolawn, and we truly appreciate your understanding and continued support. 

If you have any questions, please contact our customer support team who will be happy to help.
