Lawn Mowing is easily one of the most important aspects of garden maintenance. However, with the British weather ever changing and being as unpredictable as it is, it can be difficult to know exactly how often to do it. For this reason, as a garden maintenance and green waste company, we have put together this complete guide of when to cut your lawn throughout the year. 

So How Often? 

Unfortunately, there is no simple and straightforward answer to this question. There are many different variables that will impact this decision including heat, water and nutrients. Factors such as these will determine the speed of your grass growth. However, should you live in the UK there are some general rules you can follow. 

In the UK between March and June, the weather conditions during these months would normally require you to only cut your lawn once or twice a month. However, as the weather gets warmer in and around July, you may consider cutting your grass once or even twice a week for proper maintenance. 

Remember when you cut grass, it can be beneficial here and there to collect grass clippings for fertilisation.

The Year’s First Cut 

Most people will cut grass for the first time as the weather begins to get warmer – often around March – April time when the grass noticeably starts to grow. The first cut of the grass growing season may also be the most important. People in the UK appreciate a short, well kept lawn. However, despite this fact, many will cut the grass way too short on the year’s first cut. 

Remember the one third rule. Never cut more than a third of the blade of grass off at once. This can stress the grass. This can be seen when grass turns a yellow or brown colour. 

In order to achieve the length of grass you want, you may need to cut your lawn over a number of weeks. To do so, gradually decrease the cutting height of your lawn mower over a number of weeks until you achieve your desired length. 

Often people in the UK will cut their grass a little shorter than those living in mainland europe. However, shorter doesn’t mean better and grass height should vary over the course of the year. 

You should also find the frequency that you cut grass will decrease as the weather cools off towards the beginning of Autumn, around September to October.


We hope this guide shed some light on how often you should cut your grass. To recap briefly, around March and June, you may only need to cut your grass once or twice a month. However, in the warmer months around July, you may need to increase your grass cutting to as much as once or twice a week for proper maintenance. Remember to stick to the one third rule, not cutting your grass so short as to stress it.
