Leatherjackets 0, Us 1!

Our poor lawn was in a very sorry state after leatherjackets had a right old feast on it. These pictures were taken on 24 April this year and I really didn’t hold out much hope. However, with your grass seed and some considerable patience and persistence on my partner’s behalf, it has come back! We took these pics today (12 June) And it’s come back stronger, greener and more beautiful than before! We’ve been so impressed we’ve signed up for the quarterly subscription. Thank you for helping to save our lawn!

Lawn has thickened and is looking great

Have been persistent after a few failed attempts due to not following instructions properly but there is definitely an improvement in the lawn now and it's all thanks to you guys

Excellent - you don’t need professionals

After spending a fortune on a quarterly service with a professional company, I decided to take matters into my own hands once my lawn’s condition receded.

Lawn pack is simple. Easy to follow you you don’t need a million different things.

We’re now 8 weeks in, about to apply iron sulphate and I’m excited for the next phase of the renovation

Lawnpack has worked wonders

2 years after moving into our new build home my patience like the lawn was wearing very thin and thoughts of fake grass were increasing. Then I saw the Lawnpack advertised . I ordered a spring pack with extra seed and after waiting what seemed an age for the right soil temperatures I finally started the process on 4th May 2026. 38 days in and I am absolutely delighted with the results. The application was made simple following the instructions in the guide booklet. I covered with fleece for 19 days . I have some thinner areas that are due to my cautious spreading of the seed particularly edges near patio slabs. I have a stubborn patch that I need to tackle which was present before the application. But confident the Lawnpack experts can help me with. I also found the Facebook group very helpful. The rich initial green colour is fading very slightly but anticipating the week 8 Deeper Green Iron Sulphate application will rectify this .
I have subscription for the seasonal packs too as I intend to not loose all the hard work getting to this stage.
All in all very happy.

Hey Anthony, thanks for reviewing us! You've done such a great job with the lawn and we're delighted to see such an improvement in just over a month. Glad to hear The Lawn Club has been helpful too!

A Lawn Revitalised

A Lawn revitalised!! I purchased the spring pack as my lawn had been neglected for a few years after unfortunately having to rent my house. I took the time to do all the prep (scarifying + aerating + weed control + top soil/lawn sand)
I was patient, waited until the night temperatures were over 5 degrees for a week plus then I seeded.
My back lawn is south facing so it did grow quicker than my north facing front lawn but I am so pleased that my hard work paid off! And The Lawn Pack definitely helped as there is no guessing what to put down and when.
The key is prep and then patience.

Hey Samantha, thanks so much for reviewing us and sharing the pictures. Love to see such healthy, thick grass! Really glad the hard work paid off for you, and that you check out our Seasonal Pack Subscription for ongoing care moving forward ☺️
