Ferrous Sulphate Lawn Greening Tonic 25kg

Ferrous sulphate (iron sulphate) is a popular lawn treatment used to improve the appearance of tired-looking grass, helping to green up the lawn and encourage a stronger, more resilient finish. It can be applied dry or diluted in water, making it flexible for different garden routines.

Supplied as a raw, water-soluble crystalline product that dissolves readily for liquid application. As this is supplied in a plain bag, the product may compact during storage and transport; any lumping is due to the weight of the material and can be broken up in the bag before use.

Ideal for home gardeners as well as greenkeepers and grounds staff, particularly during the main growing seasons when lawns benefit most from conditioning. Always test a small patch first and adjust strength carefully to avoid over-application.

Ferrous sulphate can also be used to help acidify soil for ericaceous plants such as azaleas, camellias and rhododendrons. Mix with water to create a solution suitable for your chosen application method, and apply evenly for consistent results.
