A lush green garden is an obsession for many Brits.

Symbolising care, dedication and hard work, a properly maintained and finely shorn lawn is a hot conversation starter at family BBQs. And watching people fawn over your lawn can offer a real sense of pride to a dedicated gardener.

But if the weather warms up, a heatwave hits and the council enforces a hosepipe ban, keeping your garden a glowing green can start to be a real problem.

Fortunately, keeping your grass green during hot summer months is not that difficult. All you need to do is have the correct gardening procedures in place and you can easily tilt the odds in your favour.

In this post, you’ll learn:

  • How to prepare your grass for hot weather
  • How to keep your grass green during hot weather
  • How to water your grass during a hosepipe ban

How to prepare your grass for hot weather

The grass species found in the UK is a cool season grass that does not enjoy hot, dry weather. The only sure way to stop it drying out is to keep it well watered. Unfortunately, hot dry weather often ends in a hosepipe ban. Hosepipe ban = no water. No water = dry grass. Dry grass = patchy brown grass. Follow these tips to prepare for a heatwave.

Install a water butt

British summers are like a roller coaster. One minute it's pouring rain for weeks. The next, you’re only allowed to use a tap in an emergency. Don’t let all those spring showers go to waste. Buy yourself a water butt, set it up against a garage or shed drain, and create your own water reservoir.

Buy a water butt pump

During a heatwave, the hosepipe is quickly going to be off limits. Thankfully, if you followed the advice above, you should have an overflowing water butt waiting to water your lawn. Unfortunately, your problem now is finding a way to move that water around your garden with ease. If you have a large garden, using a watering can is going to be back-breaking work. Our recommendation is to buy a water butt pump. Costing about £40 to £50, all you need to do is drop the pump in water, turn it on and easily spray water around your garden using the attached hose.

Don’t plant turf during the summer

Summer can be a popular time to sort out a garden. As the saying goes, “sun’s out, garden tools out”. However, if you're thinking of getting fresh turf laid, you are probably best waiting until autumn or even the following spring. The risk of hot weather killing the grass before it takes root is quite high.

Utilise well or stream water

If you have access to a well or running water, a good option is to set up a jet pump or some type of submersible pump. These pumps can be placed in water, a hose can be attached and the pump can be used to transfer water directly to your garden. You can even set up a jet pump with sprinklers. The great thing about jet pumps is that they are quite easy to set up and, once in place, you can often forget about them due to the built-in safety devices that stop the pumps running dry.

How to keep your grass green during hot weather

There’s nothing more pleasant than waking up to a lush green lawn on a hot summer’s day. Unfortunately, if the heat is expected to last more than a few days, you have to start adapting your gardening habits to keep the grass green. Follow these tips to maintain your grass during a heatwave.

When should I mow the grass?

  • The grass should only be mowed in the early morning or late evening. This is because the grass is better equipped at these times of the day to retain moisture and resist drying out when compared to mowing the lawn during the summer heat.

How often (and how much) should I mow the grass?

  • Contrary to popular opinion, grass should be mowed frequently during a heatwave. This is because the freshly cut grass acts as a layer of mulch protecting the root systems underneath. However, set your mower blades to the highest setting. The cutting height should be at least 3 inches as the taller blades absorb the heat, leaving the grass underneath to maintain its moisture.

Should I remove or leave freshly cut grass?

  • If your lawn mower collects grass clippings, it can be a smart idea to leave a light sprinkling of cut grass on top of your lawn to act as a mulch. This mulch protects the root system underneath, ensuring the grass retains water and doesn’t dry out.

How often should I water the grass?

  • Water is the most important ingredient in a healthy green lawn. That means your garden needs to be frequently watered. The general advice is to water the grass once or twice a week. However, if the grass stays matted when stepped on, or it starts turning a greyish blue, you should water as soon as possible.

How much water does the grass need?

  • Your grass needs watering right down to its deep roots. That means you need to add about 1 to 1 and a half inches of water once or twice a week (depending on the temperature). This allows the soil to absorb as much of the water as possible, supporting the health of the grass above. Remember, only water during cooler temperatures. This reduces the amount of water evaporating and ensures as much of the water gets absorbed by the roots as possible.

Should I aerate the lawn?

  • A soil bed can become hydrophobic during a heatwave. This is where the soil starts rejecting the water, creating puddles on the surface and damaging the grass further. That’s why aerating with a lawn aerator or garden spike can drastically improve lawn health. The holes help the water reach the root zone, supporting the health of the grass on top.

Are pets allowed on the lawn during a heatwave?

  • Pets can be the real enemy of lawn care during a heatwave. Their waste over fertilises the lawn, causing the healthy green grass to turn brown. It’s important you either restrict a pet’s access to the grass during a heatwave or repair the brown spots as soon as possible.

Should I apply fertiliser during a heatwave?

  • As the UK has a cool-season grass species, its best not to fertilise during a heatwave. This is because the added nitrogen can suck water out of the grass, causing the grass to burn. Your focus should be on ensuring the grass is watered regularly to allow root growth.

Should I do any seeding or weed control during a heatwave?

  • It sounds a little counterintuitive but hold off on any maintenance like seeding or weeding during a heatwave. Your goal is to avoid hard or sandy soil, which can be exacerbated by seeding or weeding.

How to water your grass during a hosepipe ban

The most important thing you can do to protect the health of your lawn during a heatwave is to ensure its regularly watered. Unfortunately, as we know, heatwaves often lead to a hosepipe ban. That’s why preparing for a heatwave is so important to a dedicated gardener. If you haven’t prepared, follow this advice:

Water with a watering can

If you have a small garden, two watering cans before 8 am can do the trick.

Make a water butt

If you have a big garden, then its time to get creative and make a water butt. Large containers, recycling bins or even paddling pools can be used as a makeshift water butt. Again, buy a water butt pump to help transfer the water to your garden. Your back will thank you.

Divert bath/shower water

If you’re in for a long heatwave, a smart idea is to divert bath and shower water from the drain pipe to a makeshift water butt. A recycling bin will do the trick in a desperate situation.

Don’t waste washing up water

Even dirty washing up water can help when water is in short supply. Don’t just flush it down the drain, take it outside and water your plants. Even a little water can go a long way during a heatwave.

Water grass from a well or stream

If you’re lucky enough to have a local well or a stream that runs through your garden, then you can pump water directly from the water source to your garden.
