Soluble Sulphate of Iron 20%Fe Lawn Tonic and Grass Hardener

Our Sulphate of Iron lawn tonic and grass hardener is an excellent choice if you are facing a moss infestation, Iron deficiencies or high alkalinity in your soil.

Elixir Gardens Sulphate of Iron contains a very high concentration of iron, which makes it an extremely effective method for preventing or removing moss. Treats 50m2 per kg.

Iron is important to the plant for chlorophyll synthesis and for developing leaves. An iron deficiency prevents cell division and therefore growth. Our Iron Sulphate is also perfect for hardening and reducing susceptibility to disease and cold damage.

The grass will respond quickly to treatment turning a beautiful dark green.

Recommended Application: 15 – 30gm².

We recommend that you are careful not to get any of the product or dilute mixture on surfaces such as: stone, wood and concrete as Sulphate of Iron can stain these surfaces.

As Sulphate of Iron is acidic it can be used to counter over-alkalinity in your soil, allowing lime hating plants such as Camellias and Heathers to thrive. It also reduces worm casts, making your garden less muddy and slippery during the rainier seasons.

Sulphate of Iron should be applied every 4 – 6 weeks, starting in the growing season from March to the end of August. If using to kill moss it is recommended you use the higher application rate for 1 application, and then wait for 5 – 14 days before scarifying the area to remove blackened moss. Then continue regular applications every 4 – 6 weeks at the lower concentration.

This Product comes in bags up to 25kg.
