How to Revive Your Lawn After a Heatwave

The summer heat can be harsh on your garden, leading to persistent drought conditions. Extended periods of high temperatures and minimal rainfall result in yellow patches in the grass and a brownish tint on your lawn. How can you revive your lawn after such a heatwave? Find out here!

Don’t mow the grass too short

During and after a dry period, it’s best not to mow the grass too short. Longer grass is less vulnerable to scorching. Additionally, it retains moisture longer, which is very welcome during a heatwave. If the grass has turned yellow due to the heat, it’s better not to mow it at all. This will do more harm than good. First, ensure that the grass regains its green colour.

Water, water, and more water!

What does your garden really need now? Water, and lots of it. The yellow-brown patches are due to a lack of water. You might think: I’ve watered my lawn often this summer, so why is it still dry? This can be due to scorching. If the sun shines on your lawn all day, the water evaporates before it reaches the roots. This is known as scorched grass, and it’s quite common, even if you’ve been watering.

Our watering tips

• Water your lawn thoroughly twice a week after a heatwave. Run the sprinkler for 20-30 minutes.
• The best time to water is in the morning. This allows the water to soak into the ground before the sun reaches its peak and evaporates it, leading to scorched grass. Watering in the evening means the grass won’t be dry before nightfall, which can lead to diseases and mould.
• The roots need to get wet, not necessarily the blades. In fact, the blades can bend under the weight of water from above. Therefore, water close to the ground, for example, with a drip system.
• Use a sprinkler with a gentle spray. After a warm period, the grass is extra vulnerable, so a gentle approach is needed.

Give your lawn a boost

Is water alone not enough? Give your lawn a boost by fertilising it. Choose a fertiliser with a higher potassium content. Potassium improves cell structure and increases the grass’s resistance. This will really help your lawn recover. Another plus: you’re also preparing your lawn for autumn and the coming winter.

Fertilising in 5 simple steps

Are you ready to get started? Follow this step-by-step plan for the best results.

Step 1: Choose the right moment
Wait to fertilise until the first signs of rain appear, or better yet, just before a shower. Make sure the grass is dry when you fertilise.

Step 2: Prepare your lawn
Remove leaves and twigs from the lawn and mow the grass.

Step 3: Calculate the required amount
Weigh the correct amount. Multiply the number of square metres of lawn by 25 grams, and you’ll know how much fertiliser you need.

Step 4: Distribute the fertiliser
Divide the fertiliser into two equal parts. Spread the first part lengthwise and the second part widthwise.

Step 5: Water
Now, wait for that rain shower. If the rain is delayed, water the ground yourself to activate the fertiliser. Do this with a gentle spray so the granules don’t move.
