    Magic juice….Green grass…. Black feet!
  

*by M***. on Reviewed in the United Kingdom on 8 July 2023*

This is a great product for greening and hardening my lawn. Used it for several years now and will continue. I do water my lawns with sprinkler during hot spells but I think it helps lawn cope with drought. I apply by watering can using rain water two monthly most of the year. A 2.5 kg tub lasts a year on my 200 sq m lawns. Fantastic value.Iron sulphate stains hands so wear gloves, also stains feet!! I regret wearing flip flops while using it, takes a lot of scrubbing to get it off.
