This popular easy to use product is very effective in giving your lawn that Spring boost. Consisting of Ammonium Sulphate, Iron Sulphate and sand, it is not to be confused with sand for ‘top dressing the lawn’, which has no chemical content. Lawn Sand will help kill existing moss on a lawn and many different types of weeds, while at the same time helping to green up your grass. However, it will not cure a moss problem, which will require alternative stronger treatments.The lawn sand is also ideal to improve boggy and clay based soils. Another benefit of lawn sand is that it is safe to use and easy to apply. Lawn sand can be applied to lawns and amenity areas for the majority of the year, providing there is no frost or drought.
