This easy-to-spread fertiliser contains iron sulphate, which works quickly and gives your grass a deep green colour. 


The high iron sulphate concentration increases your lawn’s resistance to moss, weeds, pests, and diseases, helping it recover after its winter dormancy and redevelop its lusciousness. 

Iron Plus 2-in-1 fertiliser improves the cell structure of the grass, making this product the  perfect preparation for scarification. Ideally, use Iron Plus a week before dethatching. 

If you’re planning a BBQ or a garden party, you’ll want your lawn to look its best. The fast-acting iron sulphate gives your grass a colour boost in just two days, but for the full effect, it takes around a week. Water your lawn immediately after use for more rapid results.


  • Moss free & lawn feed in one. No additional products, expenses, or work required.
  • Fast results! A colour boost in 2 days and a total transformation in colour in just one week. Perfect for use after the cold winter months 
  • Easy to use - includes detailed instructions and gardener-friendly packaging. Resealable for safe storage.

Not suitable for freshly seeded grass (less than three months) 

Perfect as a spring, late autumn, or winter dethatching fertilizer
