5 Simple Tips for a Healthier, Thicker Lawn

Getting the perfect lawn is about more than just making your neighbours jealous. (Though it’s part of it!).

A thick and healthy lawn improves the air quality in your garden. Thicker turf releases more oxygen for you and your family to breathe, captures dust from nearby roads, and keeps your garden cool in the summer heat. 

A healthy lawn also means healthy soil, which provides a home for insects and worms, which in turn feed birds and bring more wildlife into your garden. And what’s more, a healthy lawn, soil, and root system are more resilient against weeds, heat waves, and droughts. Meaning your grass really will always be greener on your side of the fence.

So how can you make sure to keep your lawn healthy this year? Sunlight is a big factor, of course, but sadly here at Cornwall Lawn Robotics, we can’t do much to guarantee sunny days. (Though, trust us, we would if we could!).

Read on to find out what you can do for a lush, green lawn this summer.

1. Keep your grass at the right length

For a strong, healthy lawn, keep your grass at a constant length of between 2-4 inches long. This way it will more successfully outcompete weeds, and develop longer root systems, making it more resistant to drought.

If your grass is too short you risk it drying out in hot, dry weather. Or you may encourage mossy patches to take over your lawn.

Cutting more than a third of the length of the blade at any one time can cause stress to your lawn. But when the growing season is in full swing, your grass can grow up to 6 inches a week, which means you’ll need to mow your lawn at least twice a week to keep it a constant length.

But if you don’t have time to mow your lawn twice a week without fail, let a robotic lawn mower take care of it for you. Simply set the mowing height and it keeps your lawn the perfect length seven days a week. 

And because it mows continuously, it only needs to cut a tiny amount each time. This reduces the stress on the turf and your lawn becomes even thicker and more resilient over time.

2. Keep your lawn moist

Now, water isn’t something we’re short of here in Cornwall. But even we can experience droughts and heatwaves in the height of summer. 

Stopping your lawn drying out during these spells can be a constant battle. And constant watering isn’t good for your wallet, your precious spare time, or the environment.

Thankfully, because your robotic lawn mower mows little and often, it leaves the tiny amount of grass it cuts behind, creating a layer of organic mulch for your lawn.

It’s so small you won’t even notice it, but your lawn will. It locks in more moisture to the soil, meaning your turf is in less danger from drying out – even when you don’t have time to water it. Saving you time and money.

If you do still need to water, particularly during very hot spells – we recommend watering early in the day. This avoids too much water evaporating in the hot sun, saving your lawn, and saving you water, and money.

3. Improve your drainage

Poor drainage is often a result of compacted soil. This can lead to problems with water pooling, slow nutrient absorption, and lack of air circulation leading to root rot. In other words, poor drainage means poor turf. 

Lots of footfall, kids running around, or mowing with heavy roller lawn mowers can all lead to compacted soil. (Don’t worry, robotic lawn mowers are light enough to not compact your soil).

To avoid compacted soil, go round your lawn about once a year with a garden fork, punching regular holes in it about 3 inches deep. This allows air and micro-organisms to get to the soil, breaking it up and giving your lawn the perfect medium to grow in. 



4. Keep your lawn mower blades sharp

We understand – you have lots to keep on top of, and remembering when you last changed your lawn mower blade isn’t high on your list. But cutting your lawn with a blunt blade will tear the grass, turning the ends of the grass yellow, and then brown. 

If you’ve followed all the tips above and grown a thick, lush, and healthy lawn, it would be such a shame to turn it brown with blunt lawn mower blades. Fortunately, our Ambrogio robot lawn mowers use 4-edged solid stainless steel blades, that last far longer than the average lawn mower blade.

We recommend an annual service to all our customers to check over your robot mowers and make sure they’re ready for the year ahead. During your service, the condition of your mower blades will be checked and replaced if they’re in danger of ripping the grass. So that’s one thing you can cross off your list.

5. Feed your lawn with... grass!

Grass is a plant just like any other, and to grow and look its best, it needs food.

Apply a fertiliser with a mix of nitrogen, phosphorus, and potassium 2-4 times a year for optimum growth. Organic fertilisers are best, as non-organic treatments can contain chemicals that upset the natural eco-systems supporting your garden, and damage those further afield as they leach off and drain away. 

However, we get it, organic fertilisers can be expensive. And keeping up with what is toxic and not can be a headache. So why not feed your grass with grass? It’s rich in all the nutrients grass needs – because, well, it’s grass!

The mulching effect of robot mowers adds these nutrients back into the soil organically, via the grass clippings it leaves behind. This not only encourages soil microbes which convert even more goodness from the soil, but it wastes no energy – as it feeds the soil that it grew from. It’s the ultimate organic food cycle. And it costs you nothing extra.
