I spread this product by hand. So it was my fault I applied too much in a few areas of lawn. This lead to the grass being scorched.

First time I've ever bought lawn fertilizer. I've inherited a very weedy lawn, which I'm attempting to renovate using a combination of selective weedkillers and lawn feed. One application so far and the growth is noticeably lusher.

We purchased this particular product to try to rid/reduce the red thread in our lawn. Application easy and within a short time the lawn appeared thicker and more green. Early days yet but looks as though Lawnsmiths advice in using fertiliser is correct.

After using your new lawn fertiliser on my rear lawn and it working so well I've used this to perk up my small front lawn that was looking a bit brown and patchy. Spread by hand due to the size of area but it has worked amazingly in only a few weeks and didn't stain the hard surfaces I hit when I missed the lawn. Lawn is now a lot fuller, lusher and greener despite it being late in the season for the 1st application. I'm a casual novice lawnsmith but even I can get these products to work. Would highly recommend.

Having used a spring feed and moss killer earlier in the year I was looking for a summer top up for the lawn but without the moss killer element. This was surprisingly hard to find in my local garden centres but happily Lawnsmith Spring and Summer Fertiliser was the perfect match for my needs. The information provided on the website was really helpful and the ordering process easy to follow.

An excellent product for anyone who likes to care for their grass. As long as your lawn is watered this product will strengthen and thicken your grass helping with weed control(thicker healthier grass means less weeds) the only downside is you will have to mow more often as your grass will grow quicker, thicker and greener. An excellent product
