About The Fertiliser

  • Slightly increases soil acidity which can deter leatherjacket and chafer grub infestations
  • Dilute in water and apply using a watering can with a fine rose head or a pressure sprayer. Follow guide provided with purchase for application and dilution rates.
  • Avoid spraying on hard surfaces as it stains easily.
  • Full application guide provided with purchase.

**Due to recent changes in the law, products which contain iron sulphate can no longer be claimed to have control against moss. This is because any product which 'controls' moss is now classed as a herbicide, and this requires the product to have an expensive and complex approval. Due to this, we are unable to claim that this product will control moss; In spite of the fact that the product formulation has not changed since when it was used to control moss with very good results**

Additional Information

  • Can be applied any time.
  • Keep products and packaging away from children and pets prior to application.
  • Follow all safety information on all product labels.
  • Please wear gloves when handling products and keep away from eyes and mouth.

Magnificent Results

I decided to try Lawn Pack on my struggling lawn from spring 2025.
It was easy to follow the instructions
and this led to my lawn looking lush, green and thick all through the year.
Thank you Lawn Pack.

Wow - even my wife is thoroughly impressed after thinking I'd destroyed the lawn for evermore.

Delighted with my results, needed more seed than I ordered though to fill some gaps but I was starting from a particularly bare lawn (I scarified it right back to essentially bare soil and I did also use top dressing). Getting the treatment down in even quantities was challenging and I didn't manage it particularly well but it didn't seem to matter. I did keep the lawn watered every day or 2. 1st photo below from 6th Sept-25 after laying the seed. 2nd photo from 6th Oct-25. Results are better now than the 6th Oct photo (the dark areas now completely green - these were the patches that needed additional seed). I did find that the seed grew better when using the lawn dressing which i purchased separately. My lawn is pristine, has never looked better and my wife has been proved thoroughly wrong!

Hey Tom, thank you so much for taking the time to leave a review! We're thrilled to hear that both you and your wife are impressed with the results. We're sorry to hear that you needed more seed than you originally ordered, but we're glad that it ultimately helped fill in those gaps. We appreciate your feedback on the challenge of getting the treatment down evenly, and we're happy to hear that it didn't affect the end result. It's great to hear that you kept up with watering and that the results are even better than the photos. Thank you for choosing our product and for sharing your experience with us 😁

Take a look into our seasonal pack subscription service too so you can maintain the lawn you've worked so hard for!

Pleased with results

I was a sceptic at frost but thought I would give it a try. I subscribed to the four deliveries each year to help me rejuvenate my front and back lawn, back in the spring I followed the instructions as given in the pack the seed was a little slow to germinate due to the cold weather, but once things warmed up the fertiliser and seed really made a big difference to our sorry looking lawn. Even with warning a dog, the grass still looks very healthy for the time of year I would recommend giving this product to try. I have included some before and after pictures.

Hey Andrew, thanks for the review! We are so happy to hear that our Seasonal Pack Subscription has made a positive impact on your lawn. We appreciate your trust in our product and we're glad it exceeded your expectations Your before and after pictures are amazing, keep up the great work.
