Alexander Merry
Applied the autumn/winter fertiliser just before last winter and grass looking the best ever. Has been cut twice now (April) and looks great.
If the spring and summer fertiliser works as well I will be highly delighted.

Best fertiliser I have ever used. I use the shoulder spreader from Lawnsmith to apply. Quick easy and very effective. I would highly recommend. Use in spring and again in the summer

I use the product exactly as described on the accompanying instructions on a Lawn that always has a repeat dose after a few weeks. The difference is there within a week but after a month the lawn is strong and fresh. In the quantities I purchase then clearly it is for small lawns.
