    **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**

Outstanding results!

2025 has seen a very dry summer. I used the summer pack in late June, following the instructions to the letter.
I have given the grass 1 light water since using the summer pack. The results speak for themselves - a lush, deep green grass which i cut no more than once a week using a rotary mower on a medium height setting.
Put simply - it works!

Fantastic Lawn Even In This Hot Summer

Our lawn was bare in March thanks to a leatherjacket issue. After applying Nematodes, we decided to give the lawn pack a go. The results were amazing. We applied the lawn seed and fertiliser in late April when the soil was warmer and watered as advised. Following the fantastic results, we brought the summer fertiliser pack in July and the lawn looks great. I've compared what I've paid to the lawn pack against what I spent last year at diy shops. I've spent far less and have much better results. No red thread, no patchy lawn. All I've done is given the lawn a good watering early in the morning even 3-4 days. Thank you Lawn pack.

Good recovery

Last year my lawn to a battery g with the weather and leather jackets. This year however and despite the dry conditions the lawn is recovering well. I purchased the lawn complete pack and then went on to the annual subscription, so far I’ve used the spring and summer packs, autumn pack due in September. The grass is definitely greener and better rooted - I’m sure the results will only improve once we get some rain and the hose pipe ban lifted. I dread to think what it would have been like without the lawn care treatment
