Iron (ferrous) sulphate heptahydrate is a water-soluble powder containing more than 19.5% iron and 11.5% sulphur. It is a slow-release iron source, used to correct iron deficiency, deepen lawn colour and gently acidify alkaline soils. It acts more slowly than a chelate, because it works by building a longer-lasting store of iron in the soil.

Why you'll love it

  • Greening without extra nitrogen. It improves colour in lawns and garden plants without adding excess nitrogen.
  • A long-term iron store. Applied to soil or compost, it builds a reserve of iron that lasts well beyond a single feed.
  • Made for alkaline soils. It is used on soils with a pH above 7.0, where it gently acidifies the soil.
  • Used where moss invades turf. It is applied when moss begins to move into a lawn.

How to use it

Spread the powder dry, ideally with a broadcast spreader, or dissolve it in water and spray. Water the area thoroughly afterwards.

  • Iron deficiency: 20 to 30g per sqm
  • Lowering soil pH: 25 to 35g per sqm
  • Moss in lawns: 10 to 20g per sqm, every 6 to 8 weeks from late autumn to early spring

Apply on a calm day, wearing gloves and a dust mask. Iron sulphate stains concrete, paths, clothing and skin, so sweep stray powder off paving at once. Keep pets off treated areas for one week and horses for four weeks.

What's in it

  • Iron (Fe): more than 19.5%
  • Sulphur (S): 11.5%
  • Water-soluble ferrous sulphate, a slow-release iron source
