As the summer holidays approach and the weather warms up, homeowners nationwide are looking for ways to stay cool and comfortable whilst relaxing, playing and entertaining in their gardens. Artificial grass can be brutal in summer, getting significantly hotter than real grass and making your garden less enjoyable.
One simple yet powerful solution lies right beneath their feet – a healthy, green lawn. Real grass offers a natural cooling effect that can significantly improve comfort outdoors, reduce indoor temperatures, and even lead to energy bill savings. This isn't just anecdotal evidence; there's science behind it. Johnsons Lawn Seed, the experts in lawn seed take a look at why real lawns stay cool and green all summer long.
Lawns play a crucial role in cooling the surrounding area through a process known as transpiration. When plants release water vapour through small pores in their leaves, the vapour absorbs heat from the air as it evaporates, resulting in a cooling effect.
The benefits of transpiration aren't limited to just the area directly surrounding the grass. The shaded soil beneath a healthy lawn remains cooler, preventing the ground from releasing heat back into the air. Real grass absorbs less heat from the sun compared to pavement or artificial lawns due to its unique properties. All these factors work together to create a significant temperature difference.
Research has shown that a healthy lawn can be up to 30 degrees cooler than asphalt or concrete, and about 20 degrees cooler than artificial turf. This leads to a noticeably cooler yard and surrounding areas, greatly improving outdoor comfort during the summer months.
The environmental benefits of a healthy lawn go beyond just cooling. Lawns act as natural filters, absorbing pollutants and dust from the air. Unlike artificial alternatives that trap heat and contribute to runoff, real grass acts as a natural filter, absorbing rainwater and preventing soil erosion. Real grass also fosters a vibrant insect community which plays a critical role in maintaining a healthy ecosystem. Pollinators like bees and butterflies, along with predatory insects such as ladybirds and beetles, find a home in the lawn and help with plant reproduction and act as natural pest control. Decomposers like earthworms and millipedes live in the soil beneath the lawn, enriching it with vital nutrients.
To ensure your lawn maximises its cooling potential over the summer, it's important to maintain its health. Here are some simple tips:
Watering: New lawns need about 1 inch of water per week. Deep and infrequent watering encourages roots to grow deep, making the grass more drought-tolerant and cooler. Established lawns do not usually require frequent watering, if you have to water your lawn do this in the evening to minimise evaporation
Mowing: Taller grass shades the soil more effectively than short grass. Aim to mow to a height of 2.5 to 3 inches.
Aeration: Aerating compacted soil improves drainage and allows water and air to reach the grass roots more easily, promoting healthy growth and cooling effects.
Feeding: A healthy lawn is better able to withstand heat and drought. Feed according to the instructions on the label.
