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.
