This liquid lawn fertiliser helps feed and revitalise lawns and conditions the soil. It encourages healthy growth with enhanced root system development, according to the company. Apart from improving the lawn's natural resistance, it contains a wetting agent, ensuring that water and nutrients can penetrate the root system better.

Customers praised the product for being effective and easy to use. It helped promote lawn growth as well as enhance the colour of their lawn. This fertiliser also helps minimise stress from heat, drought, frost and foot traffic, suitable for use all-year-round. Many reviews said that the product helps their lawns look greener and lusher. This product is more expensive than other liquid fertilisers in the market, but customers said that its efficacy is worth the price tag. Others were disappointed that it's not quick-acting, but this seems to be a minor concern.

Apart from making their lawns thicker and greener, reviews loved that it is suitable for all lawn grasses, including Kikuyu, bent, and even buffalo.
