    15-minute comparison after a high dose of iron sulphate

    • 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.

    **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**

Astounded by the results!

Actually astounded. To be honest I felt like I hadn’t applied the product properly and thought I’d messed it up. It was dry for a few days but then it rained. These photos are about 5 weeks apart. Incredible, and the garden has stayed this way.

Mid August to Mid Sept the difference between the photos.

Wow, what amazing results That is quite the difference, thanks for taking the time to review and make sure to look into our seasonal packs to make sure the lawn stays in this condition year round!

Before and after using lawnpack.

After years of reseeding with DIY store grass seed and fertilizer, I have finally found the ONE! 100% recommend. The first 5 photos are, 19th August 2025. The second set of photos are, 4th October 2025. Used the lawn pack on 11th September.

Thanks so much for your review, Steve! Delighted we could help you get your lawn in great shape after struggling with shop bought options, it's looking fantastic.

Amazing! 5

Was skeptical! Honestly over the moon! Not going to lie because lawn was in such a bad state the prep was labour intense! The results however make it all worthwhile!! Subscription taken! Highly recommend.

Really appreciate your review, Laura! The lawn is looking brilliant, the hard work was definitely worth it 💪

Gave it a try and very satisfied

I was thinking of signing up for the seasonal subscription, but thought I’d try the Lawn Pack before committing to the full subscription
I only purchased enough for two thirds of the lawn where it was very brown with some largest bald patches
I sowed the seeds and used the complementary fertilizers. Although everything was greatly helped by a period of heavy rain, the result is very impressive , a lush very green lawn with the seeded areas taking
An interesting comparison was the other third of the lawn I put down lawn soil and seeded. The results were nowhere as good as where I used the Lawn Pack
I’ve now signed up for the full subscription I only
Service was also good

Thanks for reviewing us, Tony. Such a great improvement on the lawn, I'm glad our products got you the best results
