A thick, lush lawn can sometimes seem out of reach, but there are ways to make your grass look greener than ever - and it will work not only this summer but for seasons to come
Achieving a lush, green lawn can be quite the challenge, but it's not impossible, especially with some expert guidance. Figuring out what your grass requires to thrive can be complex, and sometimes hopes for a thick and beautiful lawn seem just a dream.
However, gardening expert Fiona Jenkins from MyJobQuote.co.uk has shared her insights on how to get your grass looking more vibrant than ever before. She assures that with the right approach, you can enjoy a greener lawn not only this summer but in future seasons as well.
‌
Fiona advises: "A lush green lawn is something that all gardeners aspire to, particularly during the summer months when we will likely be spending more time outside. There is no quick shortcut to achieving this, but with a little time and effort your grass can become thicker and greener than ever."
‌
She shared her essential tips for cultivating that perfect lawn with Devon Live. Here's what she recommends:
Feed your lawn
Selecting a high-quality fertiliser is crucial for maintaining a healthy, green lawn throughout the year. Fiona cautions that you should only feed your lawn during its growth periods, which means applying fertiliser once in spring and again in autumn.
She explains: "A quality spring fertiliser, if applied correctly, should encourage grass to grow thicker and greener. These specialised fertilisers are high in nitrate, which is key in stimulating the chlorophyll needed for photosynthesis.
"Autumn fertilisers are designed to encourage the growth of grass roots and boost the overall health and resistance of your lawn. They may not show the same noticeable results as spring fertilisers in terms of growth and colour but are important for helping your grass to stay strong against cold and frosty conditions."
Keep on top of mowing
Fiona suggests regular lawn maintenance, saying: "We are currently in the midst of 'No Mow May', an initiative that encourages people to refrain from mowing their lawns during May to support pollinators such as bees and butterflies. On the whole, however, regular mowing is an important step in making your grass greener and thicker."
‌
She further explains the benefits of consistent mowing saying: "Regular mowing encourages grass to grow through a process known as the 'stimulation effect'. The principle works much the same as how we are advised to get our hair trimmed regularly to enable it to grow faster!
"When you mow your lawn consistently to a good height you are removing the top portion of the grass blades, which prompts it to produce new shoots and leaves to compensate, resulting in a denser turf. It also has the additional benefit of removing any weeds which may be stealing sunlight, nutrients, and water from your grass."
Don't mow too short
The advice also includes a caution not to trim the grass too short. While regular mowing is crucial, it's just as vital not to cut our lawns too short. Fiona explains, "If you cut too much off your grass, you are putting excessive stress on the plants and inhibiting their ability to photosynthesise effectively by reducing the surface area of the leaves, making them weaker and more vulnerable.
‌
"Grass that has been cut too short also lacks the energy reserves necessary for developing a robust root system and will become thinner and less able to compete with weeds. For these reasons, in order to maintain lawn health and vitality, you should avoid cutting any more than one-third of the grass blade length with each mow."
Sharpen mower blades
Fiona points out the link between the condition of your mower blades and your lawn's health. She explains: "Dull blades can affect lawn quality by tearing the grass rather than making clean cuts. This leads to jagged, uneven edges on the leaves, which stresses them and leaves them looking brown and struggling to grow as they try desperately to repair the damage."
To ensure your grass remains in top condition, Fiona advises, "If you want to keep your grass looking lush you should aim to sharpen the blades on your lawn mower at least once per growing season. Using a dedicated blade sharpening tool is highly recommended as this will offer the most effective results with the least amount of effort, as well as coming with all of the necessary safety features."
‌
Overseed sparser areas
If your lawn is looking a little worse for wear with thinner patches or bald spots cropping up, you might need to consider overseeding these areas with quality grass seeds. Fiona advises: "Adding new seeds to your lawn's current grass will provide more coverage and give it a thicker, denser appearance."
Lawn aeration
Fiona says regular lawn care is essential, stating: "To achieve thicker, greener, and healthier grass you should be aiming to aerate your lawn every autumn. The process of aeration involves poking lots of small holes into the soil beneath your lawn.
"This can be done with a manual aerator or garden fork or, if you have a larger garden, you may wish to invest in an electric aerator which can cover a lot of ground in a short amount of time. Over time your lawn's soil will become compacted due to factors such as foot traffic, heavy machinery, and natural settling, which will in turn restrict root growth and impede the penetration of water, air, and nutrients. Aerating your lawn relieves soil compaction, thus enhancing root development and allowing the grass to access nutrients more effectively."
‌
Tackle weeds and moss
Additionally, it is important to combat common weeds and moss head-on. These unwelcome guests, including dandelions, daisies, and buttercups, along with moss, are commonplace on British lawns. They detract not only from the hue but also compete with your grass, hobbling its growth and sapping essential sustenance.
The expert advises: " Whilst it may be a time-consuming process, pulling out weeds by hand is usually the safest method to avoid damaging your grass – just make sure that you pull them out from the root to prevent regrowth. Many autumn lawn feeds come with a built-in moss killer, and moss can then be raked away gently around 2 weeks after application."
‌
Maintain vigilance against thatch
Fiona explains that thatch is a layer of dead grass clippings, roots, and organic matter that, over time, will build up between the soil surface and the actively growing grass. She said: "The more this builds up, the more it starts to act like a barrier, preventing water, air, and nutrients from getting to the soil. This restricts the grass's access to these essential resources, resulting in a thinner and weaker turf with a duller green colour.
"Thankfully, dethatching is a very simple process that doesn't require any specialist tools! Simply going over your lawn with a sturdy garden rake should do the trick perfectly and promote a healthier, thicker, and greener lawn."
Avoid excess shade where possible
"You have probably already noticed that grass on shady lawns grows poorly in comparison to that on lawns that get access to full sun," says Fiona. "Grass needs sunlight to grow thick and healthy, so reducing garden objects that could block it out will leave your lawn thankful.
"Of course, certain factors are out of our control, but the simplest steps like cutting back a large bush or tree could help your grass to receive those valuable extra couple of hours of sunlight a day!"
Keep lawns watered
In the UK, we're blessed with a fair amount of rain that usually reduces the need for regular watering of our lawns. However, Fiona advises that during any warmer spells, it's important to keep your lawn hydrated.
She says: "If your grass is left looking yellow and sparse due to lack of water and too much hot sunlight, it is a good idea to water it once a day during this period – just be mindful of any current restrictions, such as hose pipe bans!"
