Best lawn fertiliser

For grass that’s healthy, thick, and green, it’s worth using a lawn fertiliser regularly. Fertiliser provides lawns with the minerals and nutrients it requires while helping eliminate moss and weeds that can spoil their look. Selections range from products best applied with a spreader and those that can be applied by hand. Find the best option for you and your plot among our picks.

This lawn fertiliser is the solution to a lot of different issues in one pack. It is high in nitrogen to make the grass greener, while potassium promises to make the grass thicker. I like the fact that it helps build stronger roots, so grass can better absorb water as well as nutrients; periods of heat and drought can occur unpredictably. It’s made to be used from April to September, and although it could be applied by hand, it’s recommended to apply it with a spreader. (You’ll need to factor this in if you don’t already have one.) Note that kids and pets can’t access the grass until the granules have been watered in and the grass is dry.

If you find it inconvenient to have to keep the little ones, the family dog, and the cat off the lawn, try this lawn fertiliser. Use it, and they don’t have to stay away from the areas you’ve treated. Bear in mind, though, that its odour can attract some animals, so you will want to water it in. The treatment is organic and will feed the lawn, releasing nutrients over a period to green grass while reducing the risk of scorching. It also contains grass seed to fill any worn patches. The pack has a built-in applicator for easy spreading.

If your grass isn’t the rich, lush colour it should be, this lawn fertiliser promises to make it greener in just three days. Its effects will last for up to six weeks, though. It contains iron and has a high nitrogen level to create a healthy and desirable colour. The formula also promotes strong roots, which helps protect the grass in drought or heat. While it can be applied by hand, you’ll find it easier to use a spreader to do the job. Bear in mind that iron sulphate can cause staining on paving or clothes, so it needs to be watered into the lawn before anyone walks on it, and you’ll have to deal with any spills promptly.

This lawn fertiliser promises to feed and fertilise your lawn at the same time. Results are promised in just 7 to 10 days, and application every six weeks is recommended. I like the fact that it’s used with a hosepipe, making it simple to put on the lawn. It’s not a problem if beds get some spray, too. One pack covers a generous 300 square metres, and it’s another of our selections that promises to be safe around children and pets.

Owners of robot mowers might like this lawn fertiliser; it promises to avoid a surge in growth with a controlled release over 90 days. This means regular mowing should keep the grass looking neat all the time. You can let the robot do for you, or undertake yourself. The granules can be applied by hand, but you might find it easier with a spreader. You can even let children and pets use the lawn immediately after application. The fact that this product doesn’t have an odour is a bonus.

Opt for this lawn fertiliser if you’re keen on providing grass with organic manure and seaweed to feed and stimulate growth, respectively. It doesn’t contain a moss killer but instead relies on the growth of the lawn out-competing the unwanted addition. It’s another product that works by slow release and is designed to green the lawn for up to six weeks. Be aware that while it is safe around kids and pets, it’s another of our selection that requires that they stay off until it’s watered in and dried.

Our verdict

Keep your grass green and growing with the help of lawn fertiliser. Our favourite is Miracle-Gro Evergreen Complete 4-in-1 lawn food. As well as feeding and greening the grass, it’ll act to kill moss and weeds for a great looking lawn throughout the growing season.
