Winter pack

Received my winter pack plenty of time before I needed to use it. Applied it in about half an hour easily using the instructions provided. Contacted support for advice regarding temperatures to apply and got a quick response. Put down 2 weeks ago and the grass is looking greener and stronger already. I have now purchased the lawn pack to renovate my front lawn also and will be buying the subscription packs for it also. Picture shows my lawn before applying the lawn pack last year and 2 months later what it looked like.

Thank you for sharing your experience, Rachael! We are glad to hear that your lawn is already looking greener and stronger. We appreciate your continued support and look forward to helping you renovate your front lawn as well 😁

After First Year Of Treatments

After just one year of treatments my lawn has never looked so good and it's still only mid-February!

Hey Derek, thanks so much for the review! So pleased your lawn is looking so great after using our treatments - we love the stripes 😍

Winter pack applied and looking good

I applied the winter pack across a few weeks after first applying the Deeper Green Iron Sulphate and then a few week later the Biostimulant booster and Winter Protection Fertiliser.
It's been so wet but the lawn is definitely in better shape than this time last year.

Thank you so much for taking the time to leave a review for our Winter Pack! We are thrilled to hear that it has made a positive impact on your lawn, especially during the wet weather 😁
