    **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**

If Carslberg did lawns ..

From a lawn that 5 weeks earlier was mostly bald patches and straw coloured to a lawn that is not perfect but certainly healthy, and a lush green colour, anyone would confirm that it has been transformed. Very much for the better. It is definitely worth noting that the 5 weeks included the driest, warmest May in living memory. Here in the East of England we are particularly well sheltered from the Atlantic weather and regularly the driest part of the country anyway. This year has been particularly challenging. The attached pictures bear witness to the improvement and we are certainly very happy with the result.

Revives the lawn every year

Our back lawn gets next to zero sunlight during the winter months so always looks patchy and a bit worse for wear come spring. I used the lawn pack last year which brought it back to life within 2 weeks. I’ve since signed up to the subscription model which is excellent value for money. Applied the spring pack in April and couldn’t believe the difference it made again within 2 weeks. Pictures are from last year. Buy results this year were equally on point. I wouldn’t use anything else.

Only 3 months in!!

We can not believe the difference in our lawn after just 3 months. Having spent a fortune on gardeners and various products over the past couple of years we have been fighting a losing battle with our lawn. But the Spring lawn pack and the instructions it came with have totally rescued our lawn. We have a very energetic dog AND we have a green lawn, we are over the moon. Thanks so much!! Roll on the summer pack!!

Update review

I recently did a review I which I gave three stars as I felt I hadn’t seen a big improvement.
This then led to some advice being sent about shady lawns however I still wish they had done it prior to my order.
Yes my existing lawn has improved but what I have been advised is I need special lawn seed specifically for shade.
This would have helped greatly because when placing order I did specify for a shady area.
Still patchy but now I have the correct advice I can actually source the correct seed.
