Are You Cutting Your Lawn Too Short?
Are you trying to get that golf green look to your grass?
Unless your grass is Agrostis or Bent Grass commonly used on golf courses in the UK which is renowned for its short growth and even shorter cutting height, you may be doing more damage to your lawn than you than you think.
What’s The Best Cutting Height For My Lawn?
A lush, green lawn is a source of pride for many homeowners in the UK. To achieve the ultimate garden oasis, proper lawn maintenance is essential. One often overlooked aspect of lawn care is the length of the grass. Contrary to popular belief, longer grass offers numerous advantages over shorter cuts. In this comprehensive guide, we will explore the beauty and benefits of longer grass in UK gardens and provide valuable insights for maintaining a healthy and vibrant lawn.

The Resilience and Benefits of Longer Grass
One of the key advantages of maintaining longer grass is its ability to exhibit enhanced resilience to a wide array of environmental stressors. When the grass blades are allowed to grow longer, they facilitate a more extensive photosynthetic process. This, in turn, leads to a significant increase in energy production and storage within the grass. Consequently, the lawn becomes empowered with additional resources to withstand and recover more effectively from various adverse factors, including prolonged periods of drought, scorching heatwaves, and heavy rainfall.
The extended photosynthesis process in longer grass allows it to capture and convert more sunlight into vital energy, which is then utilized to fortify the roots, improve nutrient absorption, and maintain essential cellular functions. The surplus energy reserves act as a buffer, ensuring that the grass can better cope with challenging environmental conditions and quickly recuperate after enduring stress.
Longer Grass Improves Drought Tolerance
The UK's climate can be unpredictable, with periods of dry weather posing a challenge to lawn care. Longer grass develops deeper root systems, enabling it to tap into water sources deeper within the soil. This enhanced water retention increases the lawn's drought tolerance, reducing the need for excessive watering and conserving precious resources.
In regions frequently affected by drought, the resilience of longer grass becomes particularly advantageous. The deeper root system, supported by the extra energy reserves, enables the grass to access moisture from deeper soil layers, making it more drought-tolerant compared to shorter grass. Moreover, during heatwaves, the added energy reserves help the grass maintain its vitality, preventing it from becoming scorched and damaged.
Likewise, when faced with heavy rainfall or flooding, longer grass is better equipped to recover from the excess water. The deeper roots and increased energy stores enable the grass to withstand waterlogged conditions without suffering significant damage, reducing the risk of soil erosion and promoting overall lawn health.
Cutting Your Lawn Too Short Increases Weeds
A lush and vibrant lawn, adorned with longer grass, offers a multitude of benefits that extend beyond mere aesthetics. One of its remarkable advantages lies in its ability to serve as a natural defense against the encroachment of invasive weeds. The taller blades of the grass play a crucial role in creating a protective shield, hampering the relentless efforts of weed seeds to take root and establish their unwelcome presence.
The secret lies in the clever strategy of shading. The extended length of the grass blades casts a gentle but effective cover over the soil, obstructing the sunlight from reaching the ground below. This reduced exposure to sunlight becomes a formidable obstacle for weed seeds, as they depend heavily on sunlight to germinate and kick-start their growth process. With the sheltering presence of the longer grass, many weed seeds are thwarted in their attempts to awaken and establish themselves.
Soil Health and Erosion Prevention
The condition of the soil in your lawn is of utmost importance for maintaining its overall health and vitality. The presence of longer grass in your lawn serves a critical role in ensuring the well-being of the soil beneath.
One of the primary benefits of longer grass is its ability to trap and retain water effectively. When heavy rainfall occurs, the longer grass acts as a natural sponge, absorbing and holding onto the water rather than allowing it to runoff quickly. This water retention helps in reducing soil compaction and erosion, as it allows the soil to absorb the moisture gradually, preventing excessive pressure from heavy raindrops that could lead to compaction.
Moreover, the longer grass acts as a protective cover for the soil. The dense vegetation creates a barrier against the force of flowing water during rains, preventing the soil from being washed away or displaced. This protective function is especially crucial for areas with slopes, where soil erosion can be a significant concern.
Increase Aesthetic Appeal and Biodiversity
Beyond the functional benefits, longer grass significantly enhances the visual appeal of your garden. Taller blades create a lusher, more vibrant look, contributing to an inviting and picturesque landscape. Moreover, the taller grass provides a habitat for various insects and small creatures, fostering biodiversity and promoting a healthier ecosystem in your garden.
Tips for Proper Lawn Maintenance
Follow the One-Third Rule: When mowing, never cut more than one-third of the grass blade height at a time. Set your mower blades at a higher height to maintain longer grass.
Mow at the Recommended Height: Lawns in the UK typically consist of a mixture of grass species, including fine fescues, perennial ryegrass, and Kentucky bluegrass. These grasses thrive when mowed to a height between 1.5 to 2.5 inches (3.8 to 6.4 cm)
Avoid Scalping: Cutting the grass too short can weaken the plants and allow weeds to take over. Scalping, or cutting off too much of the grass blade at once, can stress the lawn and lead to brown patches. It's generally best to follow the one-third rule, which means you should never remove more than one-third of the grass height in a single mowing session.
Consider the Season: In the growing season, you might want to keep the grass a bit taller to encourage deeper root growth and shade the soil, which helps retain moisture. During hot and dry periods, raising the cutting height can be beneficial as well.
Mowing Frequency: Aim to mow frequently enough that you're only removing the top one-third of the grass at a time. For some lawns, this might mean mowing once a week, while for others, it could be more or less often.
Mower Blade Maintenance: Make sure your mower blades are sharp. Dull blades can tear the grass rather than providing a clean cut, leading to a less healthy lawn.
Consider Shade and Sunlight: If parts of your lawn receive more shade, you may want to keep the grass a bit taller in those areas, as they typically have slower growth rates compared to sunnier spots.
Climate and Watering: In dry climates, raising the cutting height can help shade the soil and reduce water evaporation. In wetter regions, keeping the grass slightly shorter can help prevent disease by improving air circulation.
Choose the Right Grass Variety: Select grass types that are well-adapted to the UK climate and demonstrate good growth characteristics for longer, healthier blades.
Mow Under Suitable Conditions: Avoid mowing the lawn when it is wet, as this can lead to uneven cuts and cause damage to the grass.
Aeration for enhanced nutrient absorption: Boost nutrient uptake in your lawn by aerating the soil once or twice a year. This process involves creating small holes to facilitate better air, water, and nutrient penetration to the grassroots.
Overcome thin patches through overseeding: Enhance lawn density and address bare areas by overseeding with suitable grass seeds. This practice fosters new growth and helps in achieving a fuller, more resilient lawn.
Mulch grass clippings for nutrient recycling: Instead of disposing of grass clippings, mulch them back into the lawn. This allows nutrients to return to the soil, reducing the reliance on synthetic fertilizers.
Opt for eco-friendly pest management: Monitor your lawn for pests such as insects and grubs. Use environmentally friendly insecticides when necessary, focusing on targeted treatment for affected areas.
Conclusion
Embracing longer grass in your UK garden is a decision that brings a host of benefits, including increased lawn resilience, improved drought tolerance, natural weed suppression, enhanced soil health, and a more attractive garden landscape. By adopting proper lawn maintenance practices, such as following the one-third rule, setting seasonal mowing heights, selecting suitable grass varieties, deep watering, and mowing under favorable conditions, you can cultivate a thriving and picturesque lawn that serves as a delightful centerpiece for your home and enriches the biodiversity of your garden ecosystem.
