Fantastic Lawn Feed – Works Every Time!
I’ve been using this for several years now, and it never disappoints. This product genuinely works — my lawn is always healthy, lush, and vibrant, and I get compliments on it every year. The results are noticeable incredibly quickly. Within just a couple of days, you can see the grass greening up and looking much more even and nourished. It also gives great protection against lawn disease, which really helps keep everything looking its best going into the colder months. A reliable, effective product that I will continue to use year after year. Highly recommended!

Iron sulphate for grass
4 stars due to the packaging as the powder had leaked out of the tub as the lid was slightly open. But is wrapped in bubble wrap before being packaged in a box so just be careful opening. I opened mine outside as had read the reviews and others have mentioned this. Did clog the waterspout the first time I used it but the water was cold so the second I used it I used warm water and no problem. My lawn is in a very bad state with moss and clover so have had to use it a couple of times. Definitely kills the moss and noticed the blackening within a few hours. Didn’t help with the clover but have killed of some weeds. It takes time but however with patience and a lot of hard work in clearing it but this product really helps.

Works
Where we are we are plagued with moss. Tried loads of other things and then this. Didn't take long to see the moss being affected and using a scarifier removed a lot. Regular use throughout the year not only keeps the moss at bay but the grass looks a lot healthier. Evn neighbours have noticed and commented on how good it looks. Certainly works on our lawn and will continue to use it. Update: After using it for a year the lawn is much healthier and the moss is really under control. Now have the best lawn in the street without too much effort.

Magic juice….Green grass…. Black feet!
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.
