Finding the perfect height for your lawn can be a tedious and time-consuming process, and with each species having its own requirements, it can be easy to feel left in the dark. 

As a general rule of thumb, the recommended turf length in the UK lies between 2.5 to 4 centimetres. However, there are a few other things to bear in mind when maintaining your lawn. From seasonal demands to individual grass species, the team at Grass Science Seeds have picked out their top tips to ensure that your lawn stays in top shape all year round. 

Grass Species

Understanding the different grass species and how to maintain them can be overwhelming, with each having its own recommended cutting height. Thankfully here in the UK, we only have a few common grass species, including perennial ryegrass, fine fescues and Kentucky bluegrass. 

All of these species generally do well when they are maintained within the 2.5 to 4 centimetre range. Nearly all mowers have adjustable settings which alter the cutting height, allowing you to simply switch a dial or move a lever to achieve the perfect lawn height. 

Season Variation 

During periods of active growth, such as spring and autumn, we recommend keeping the lawn slightly longer than the average range. This helps to not only promote healthier root systems but it can also help to improve the lawn’s ability to tolerate stress. 

In the summer, consider mowing slightly shorter than in the spring and autumn, as this helps to minimise the water stress and likelihood of disease. 

Mowing Frequency

Regular mowing is essential for perfecting the appearance of your lawn. Aiming to mow frequently, especially during peak seasons, helps to prevent the grass from becoming overgrown while maintaining an even appearance. 

However, remember to never take off more than one-third of the grass height in a single mowing session. By regularly mowing, you should only need to remove a small amount each time, encouraging lateral growth for a thicker and healthier lawn. 

Shaded Areas

Often, lawn growth is a lot weaker in shaded areas in comparison to areas in direct sunlight. When maintaining shady areas, it can be beneficial to introduce a slightly higher cut, which helps to promote photosynthesis and overall grass health. 

Lawn Usage

What is the specific use of your lawn? Is it primarily ornamental and not subject to heavy traffic or is it used frequently by pets or for sports? 

Typically, if the lawn is not used on a daily basis, the cutting height can be kept towards the higher end of the recommended range, resulting in a more aesthetically pleasing appearance. However, if your lawn is used frequently, we would suggest using a shorter cutting height. 

Perfect Your Lawn With Grass Science Seeds 

Mowing is a relatively straightforward process, it becomes easier with time and practice. However, while this is a general guide, it is always best to adjust the cutting height based on the specific grass species, local conditions and personal preference.
