## Description

Dark Green Lawn Fertiliser - High in Nitrogen Greens Grass Fast - Feeds up to 90 Days - Child and Pet Friendly - Garden Lawncare Guy : desertcart.co.uk: Garden

Review: Lawn feed and green - Brilliant, it actually works, I spread it on by hand, easy to do, I did it in the rain as you do have to water the lawn otherwise, 2 weeks later my Gardner came and was amazed at how green and lush the lawns looked. It transformed from hay to lush green lawns .
Review: It’s called dark green for a reason, magic stuff! - After making a mess of our lawn with a liquid feed (patchy) this stuff being granular is so much easier to apply evenly. I just bought a £9 hand spreader, it suggests to put it on the minimum setting but I ended up putting it on the largest setting because our lawn is quite small (one bag). A week later and my grass has equalised to a lovely healthy dark green. It happens gradually like it says, definitely worth taking a photo each day so you can appreciate the difference. It’s not often you buy something and see results so quickly, I am sat out in the sun just admiring my saved lawn. I’ll be doing this again and going with their autumn/winter version too. Bravo.

Turns the lawn as green as, but isn’t an effective weed killer. Promotes healthy, lush grass growth though, so not unhappy!
