How you get it done: Lawnmowing

Your lawn needs a little pampering now and then to look good and resist the attentions of weeds, moss and disease. Follow the advice below and we can promise that the grass will never look greener on the other side.

Spring clean

Before you cut the lawn for the first time, it’s a good idea to take a closer look at your lawn. Pick up any twigs, stones and other items that don’t belong on the lawn. But wait until the lawn is really green before you rake it, otherwise you could damage it. You can give the lawn its first cut when the grass gets longer than 40–60 mm.


When you mow the lawn it removes nutrients that the grass needs to grow and resist weeds. Set the cutting height a little higher than normal the first few times you mow in spring, as this will help it grow.

The lawn grows fastest during the early part of the season, so you should mow it once or twice a week. When summer reaches its peak the grass grows more slowly and after summer, the growth rate picks up again, then slows down in autumn, and stops completely when the frost arrives.

Cutting height

Never cut more than half the length of the grass blades at each mowing. As a rule of thumb the grass should not be shorter than four centimetres. You should avoid mowing when it is very hot and sunny, as the grass is at its most vulnerable then. And of course it’s more relaxing for you to mow in the cool of the evening.

Cutting blade

A sharp cutting blade is important. If the blade cuts the grass cleanly it reduces the risk of the grass drying out or being attacked by disease. Diseases can attack frayed grass much easier, and the lawn may turn brown and weeds will find it easier to take root. View replacement blades here.


If your lawn is affected by moss you should use a scarifier to allow more nutrients to reach the grass. Moss usually appears when the grass is not getting enough air and nutrients. By scarifying you remove the moss and sever the roots of grass, which encourages it to regenerate. You also clear dead plant material from the surface at the same time.

Scarification is most effective when the soil is a little damp and soft, usually in spring and autumn. The result will be a hardier lawn with greatly improved aeration, improved water penetration and fewer weeds.


How often you need to fertilise the lawn depends on the amount of wear it is subject to. However, three times a year is suitable for the average lawn: in spring to help the grass revive after winter, in late summer to support strong growth, and in autumn to provide energy reserves until next spring.
