Fertilizer: Sulphate of Iron

Sulphate of Iron improves soil conditions for acid loving plants.

Sulphate of Iron can be used to reduce the alkalinity of soils, helping make available the natural elements and nutrients essential to the healthy cultivation of plants which thrive in acid conditions.

Iron sulphate (Iron sulfate) or ferrous sulphate (ferrous sulfate) is the chemical compound with the formula (FeSO4), known since ancient times as copperas.
  • All calcifuge (lime hating plants) such as blueberries, azaleas, rhododendrons, magnolias, conifers, as well as many ericas and alpines can benefit from regular top dressing with Sulphate Of Iron.
  • It helps to correct chlorosis, most effective on neutral or slightly acidic soils.
  • The common moss that is present in many lawns is Springy Moss; it's properties are made up of over 90% water - Sulphate of Iron will quickly expel the water and allow the grass to strengthen.
  • Always try to apply Sulphate of Iron on a dry still day but with rain imminent - ideally no longer than 12 hours .(this is to avoid scorching) the moisture dissolves the sulphate of iron.
  • It is inadvisable to store open bags sulphate of iron through the winter - the dry powdery material absorbs even the lightest of atmospheric moisture and the material can become lumpy and unworkable through a drop spreader - try to buy just enough for your needs
