Best lawn maintenance tips

Below, I’ll take you through my annual routine tasks for the lushest lawn. The points I’ll cover include:

  • Keeping the grass trimmed
  • Regular watering
  • Feeding with fertiliser
  • Aerating the lawn
  • Controlling weeds
  • Dethatching
  • Seeding patchy areas
  • Snow and leaf removal
  • Sunny and shaded areas

Keep the lawn trimmed

A very basic first step is to stay on top of mowing the lawn. This seemingly simple task holds the power to shape the health and aesthetics of your grassy expanse. Striking the right balance between length and frequency is key. While you wouldn’t want an overgrown wilderness, going too short isn’t the solution either. To find the sweet spot, aim to mow when your grass reaches about 90mm (3 ½ inches) in height. This encourages a healthy grass structure while allowing sunlight to reach the base, aiding overall growth.

Remember, your lawn is attuned to the environment. Seasons and conditions play a pivotal role. Warm, rainy spells accelerated growth, necessitating more frequent mowing. In contrast, colder and drier periods might slow down growth, granting you mowing reprieve. By attuning your mowing schedule to these rhythms, you can harness nature’s sway to your advantage. Consider mowing not just as a chore, but as an artistic choreography that nurtures your lawn’s vitality.

Further on in this article I’ll talk in more detail about mowing techniques for the best results.

Water the grass on a regular basis

Consistent watering is a cornerstone of effective lawn care, but it comes with a nuanced approach influenced by the changing seasons. Your grass thrives on regular moisture, which can be provided either through natural rainfall or your own irrigation efforts. If your region enjoys frequent and adequate rainfall, the need for supplemental watering diminishes.

watering the lawn

The key is to establish a well-defined watering routine that adapts to the seasons. We recommend that you provide your lawn with around 1 to 1.5 inches of water each week. How much is an inch of water? A simple way to measure this is to place a tuna can under the sprinkler, when this has filled to a depth of one inch, you can turn the sprinkler off.

This can be divided into 2-3 watering sessions, ensuring that the soil receives a deep, thorough soaking rather than a superficial misting. The best time to water your lawn is during the early morning hours, typically between 4 a.m. and 9 a.m. Watering in the early morning offers several advantages. The air is cooler, which reduces evaporation, allowing water to penetrate the soil and reach the roots more effectively.

Watering amounts will change throughout the year depending on the amount of rainfall in your area. We live in Cornwall where these average amounts are recorded.

I generally only water the lawn during periods of low rainfall. If the forecast suggests no rainfall for more than 3 days, then my watering schedule begins.

Feed your lawn the right fertiliser

Nourishing your lawn with the appropriate fertiliser is a pivotal element in its journey to vibrant health. Think of fertilising as providing your lawn with a balanced diet tailored to its specific needs. The key lies in understanding the types of fertilisers available, their composition and the optimal timing for application.

Fertilisers come in various formulations, each designed to address specific aspects of your lawn’s nutrition. These formulations are commonly labeled with three numbers, indicating the percentages of nitrogen, phosphorus, and potassium they contain. Nitrogen promotes lush green growth, phosphorus supports root development and potassium contributes to overall resilience.

Choosing the right fertiliser means aligning its composition with your lawn’s current needs. Early spring calls for a nitrogen-rich fertiliser to kick-start growth, while autumn might require a potassium-focused blend to bolster winter hardiness. Applying fertiliser during periods of active growth, usually in the cooler parts of the year, helps your grass absorb nutrients more effectively.

Precision matters too—over-fertilisation can lead to excessive growth and potential damage, while under-fertilisation might result in lackluster health. Following the manufacturer’s guidelines and local recommendations ensures you’re providing just the right amount.

Lawn aeration

Aeration stands as a fundamental technique in fostering a thriving lawn. By delicately puncturing the soil with minute holes, this process offers a multitude of benefits. Enhanced air exchange, improved water penetration, and optimal nutrient distribution become attainable, invigorating the grassroots environment.

Aerating the lawn

Beyond these gains, aeration holds the power to alleviate stubborn soil compaction—a common obstacle to healthy growth—allowing roots to stretch and breathe freely. In embracing aeration, you’re not just tending to the surface aesthetics, but also nurturing the unseen world beneath, where strong and resilient roots set the stage for a truly flourishing lawn.

This low cost investment can help your lawn thrive. For small to medium size lawns this aerator is ideal.

The frequency of lawn aeration depends on factors such as soil type, lawn usage, and environmental conditions. As a general guideline:

  1. Heavy Clay Soils: If your soil is heavy clay and prone to compacting easily, consider aerating once a year, preferably during the growing seasons of spring or fall.
  2. Moderate Soils: For loamy or moderately compacted soils, you can aerate every 1-2 years, depending on how quickly compaction returns.
  3. Sandy Soils: Sandy soils typically don’t compact as easily, so you might only need to aerate every 2-3 years.
  4. High Traffic Areas: Lawns that experience heavy foot traffic or play activities may benefit from more frequent aeration, possibly every year or even twice a year.
  5. Lawn Health: Regularly monitor your lawn’s health and appearance. If you notice signs of poor drainage, water pooling, or areas where grass struggles to grow, it might be time to aerate.

Remember, aeration is most effective when the soil is slightly moist but not overly wet.

Weed control

Maintaining a pristine lawn requires vigilant weed management as these unsightly invaders compete relentlessly with your grass for sunlight, moisture, and nutrients. These interlopers can deprive your grass of vital resources, hampering its growth and vitality.

To give your garden the best chance of staying green and unspoiled, regularly scrutinise your lawn and promptly eradicate weeds. One effective strategy to establish control is the use of pre-emergent herbicides, which serve as a protective shield against weed germination. By curtailing weed growth at its inception, you’re fostering an environment where your grass thrives unhindered, taking center stage in a landscape free from the constraints of unwanted competition.

Dethatching, an essential practice in lawn maintenance, involves the removal of thick thatch, which is a mat-like layer of organic materials. Thatch comprises elements like dead grass, rhizomes, mulched leaves, and other debris that have accumulated and not yet decomposed. This layer can hinder water, air, and nutrient movement in the soil, potentially impeding healthy grass growth.

Dethatching is a process that helps to prevent this accumulation from becoming problematic. By meticulously clearing away the excess thatch, you’re restoring a more favorable environment for your lawn, one where it can breathe, receive proper nourishment, and thrive without the hindrance of excessive organic buildup.

Appropriate seeding

Mastering the art of appropriate seeding is a pivotal aspect of nurturing a thriving lawn. When confronted with bare or thin patches, timing becomes paramount. Early autumn emerges as the optimal window, as soil temperatures are ideal for seed germination. Capitalising on this natural rhythm sets the stage for successful growth. Yet, the journey doesn’t end with sowing.

Devote attention to nurturing these newly seeded areas, maintaining consistent moisture to ensure a nurturing environment for sprouting seedlings. As they establish their root systems, this vigilant care pays off, yielding a vibrant, seamless expanse where once-thin spaces bloom into a rich tapestry of healthy grass.

Shade and sun

Gaining a nuanced understanding of your lawn’s exposure to sunlight is pivotal when selecting the right grass varieties. Your lawn’s vitality is intricately tied to its sun exposure. For areas that receive varying degrees of shade, opt for grass varieties renowned for their shade tolerance. These adaptable types flourish even under limited sunlight, ensuring a lush carpet in spite of shading. Conversely, in sun-soaked spaces, embrace the vigor of sun-loving grass varieties.

These resilient types bask in sunlight’s abundance, thriving with vibrancy. By marrying your grass choices with your lawn’s unique light conditions, you’re orchestrating a harmonious symphony of growth, where every blade finds its place in the sun or the shade.

Snow and leaf removal

Strategic snow and leaf management plays a pivotal role in maintaining a resilient and vibrant lawn throughout the seasons. As autumn arrives, diligently clearing fallen leaves from your lawn is imperative. Allowing leaves to accumulate can lead to suffocation of the grass beneath, creating an environment conducive to disease and hindering growth.

racking the lawn

Come winter, it’s equally important to exercise care when dealing with snow. While a picturesque blanket of snow is serene, piling it excessively on the lawn can result in compaction and damage to grass underneath. By adopting a proactive approach to snow and leaf removal, you’re safeguarding your lawn’s vitality, ensuring it emerges from winter’s grasp strong and ready to flourish in the upcoming seasons.

Mowing best practices

In this next section I’d like to highlight some of the key mowing techniques to ensure your lawn has the best possible chance to grow and thrive in your garden. I’ll cover:

  • Grass clippings
  • Correct blade height
  • Dryness of grass
  • Keeping mower blades sharp
  • Mower maintenance
  • Edge trimming and
  • Patterns

Leave grass clippings

Embracing the practice of leaving grass clippings on your lawn after mowing holds hidden benefits for its overall health. Contrary to common perception, these clippings are not just discarded remnants, but rather a natural source of nourishment. As they rapidly break down, they infuse the soil with valuable nutrients, acting as an organic fertiliser that enriches the growing environment.

leave grass clippings

This sustainable approach not only minimises waste but also promotes a self-sustaining cycle, where the clippings that once thrived on the lawn now give back to it. By letting these clippings seamlessly reintegrate into the landscape, you’re nurturing a well-nourished, thriving lawn that’s in harmony with the ecological balance of its surroundings.

However, it’s crucial to avoid leaving excessive piles of grass clippings on your lawn, as they can obstruct light and impede the healthy growth of grass. If you have a compost heap or bin, it’s beneficial to incorporate a layer of these surplus grass clippings into it. This practice not only prevents lawn issues but also contributes to effective waste management and the creation of nutrient-rich compost.

Raise the blade height

One of the biggest mistakes people make when mowing their lawns is setting their mower’s blades too low. This is often referred to as scalping and it makes the lawns susceptible to weeds and infestation.

mower height

The ideal mowing height for your lawn depends on the type of grass you have. Here are some general guidelines for common grass types:

  1. Cool-Season Grasses (e.g., Kentucky Bluegrass, Fescue, Ryegrass): These grasses thrive when kept at a height of around 60 – 80mm (2.5 to 3.5 inches). During the growing season, it’s best to stay closer to the upper end of this range to encourage root development and shade out weeds.
  2. Warm-Season Grasses (e.g., Bermuda Grass, Zoysia Grass, St. Augustine Grass): These grasses can be maintained at a slightly lower height, typically between 40 – 60mm(1.5 to 2.5 inches). However, during periods of active growth, they can be mowed slightly higher to promote stronger root systems.
  3. Fine Fescue: This type of grass, often found in shade-tolerant mixtures, can be kept at a height of around 60 – 75mm (2.5 to 3 inches).
  4. Buffalo Grass: If you have buffalo grass, a warm-season grass, you can maintain it at a height of around 50 – 75mm (2 to 3 inches).

Remember that mowing height is crucial for maintaining a healthy lawn. Cutting too much at once can stress the grass and leave it susceptible to pests and diseases. It’s recommended to avoid cutting more than one-third of the grass height at a time.

Wait for your grass to dry

Whenever you plan to mow your lawn, make sure you keep an eye on the forecast in advance. You will want to avoid cutting grass while it’s wet.

Wet grass can be difficult to mow and often jams up your lawnmower, particularly when it’s long. As wet grass sticks together and leaves clumps of cut grass spread out across your lawn, you might find that these clumps form dead patches.

If you absolutely must mow your lawn while it’s still wet, be sure to remove any clumps of cut grass afterward.

Keep your blades sharp

Just as any dull knife or blade tears objects rather than slicing them, a set of dull mower blades will leave your grass with jagged edges. This causes the grass to die, turning the tips of your grass blades to a shade of brown or white.

sharpening mower blades

Make a habit of sharpening your lawn mower blades from time to time. To keep your blades sharp for longer, be sure to clear your lawn of any stones, braches, or objects before mowing.

Service your lawn mower regularly

The condition of your mower can have a significant impact on your lawn’s overall health. Before each growing season, arrange for a professional to service your mower or consider servicing it yourself. In most cases, maintenance can be performed in less than two hours!

This will ensure that the life of your mower’s engine is preserved, that its efficiency is maximised, and that the unit’s blades are both sharp and clean.

Edge and trim

Embracing the practice of precise edging and trimming is the key to maintaining a meticulously groomed lawn. Along sidewalks and driveways, regular edging creates distinct borders, conferring a clean and polished aesthetic. This meticulous separation prevents grass from encroaching onto these spaces, presenting a well-defined landscape.

edge trimming lawn

As you navigate around obstacles and borders, meticulous trimming ensures no detail is overlooked. This commitment to precision extends beyond the grass itself—it shapes the perception of your entire outdoor space, cultivating an atmosphere of neatness and care that enhances the allure of your property.

Explore different mowing patterns

Varying your mowing patterns is a vital strategy to optimise lawn health. It might be tempting to stick to a convenient routine, but this can lead to soil compaction and compromised grass growth. Instead, embrace the practice of altering your approach each time you mow.

mowing patterns

By alternating between mowing parallel and perpendicular to your property, you’re ensuring even wear on the grass and minimising stress on the soil. This proactive approach maintains the vitality of your lawn, cultivating a resilient and lush expanse that stands as a testament to your thoughtful care.

Leave it to a professional

While you might intend to give your lawn the attention it requires to grow and thrive, the reality is that you might lack the time and resources to properly maintain it.

If so, consider leaving your lawn care needs to a professional. Not only will your lawn benefit from a specialist’s touch but it will also get the full treatment of fertiliser, mosquito control, and other lawn care products when required.


In the pursuit of a lush and vibrant lawn, each step taken resonates with the commitment to creating an outdoor haven that captivates the eye and soothes the soul. Armed with an arsenal of insights and practices, you now possess the tools to nurture your lawn into a flourishing masterpiece. From the art of mowing to the science of watering, from the vigilance against weeds to the precision of trimming, your understanding has evolved into a comprehensive tapestry of lawn care knowledge.
