Don't wait for brown patches: Why preventative hydration is the secret to a summer-ready lawn

As the evenings get lighter and summer social calendars start filling up with BBQs, garden parties and alfresco dinners, many homeowners naturally turn their attention to patios, outdoor furniture and outdoor entertaining spaces. But while you're planning where guests will sit and what will be on the menu, don't forget about the lawn.

June is one of the most important months in the lawn care calendar. While grass is still actively growing, it's also approaching the hotter, drier conditions that can leave lawns looking patchy, stressed and brown later in the summer.

According to Cheryl Harper, Managing Director of Greensleeves Lawn Care, one of the biggest mistakes homeowners make is waiting until their lawn starts showing signs of distress before taking action.

"Many people only think about watering when they see brown patches appearing, but by that stage the lawn is already under stress," says Cheryl. "The healthiest lawns are usually the ones that have been prepared beforehand. June is the ideal time to strengthen your lawn, improve moisture retention and build resilience before summer conditions arrive."

Here, Cheryl shares the lawn care jobs worth tackling now to help your grass stay greener, healthier and better hydrated throughout the months ahead.

Hydration starts long before you reach for the hosepipe

When people think about keeping a lawn hydrated, they often picture standing in the garden with a hosepipe during a heatwave. But hydration is about much more than simply adding water.

Healthy soil, strong roots and balanced nutrition all play a role in helping grass access and retain moisture. A lawn that's struggling with compaction, weeds or nutrient deficiencies will find it much harder to cope when temperatures rise. By tackling these issues now, homeowners can improve their lawn's natural ability to withstand periods of dry weather later in the season.

Did you know? Grass with a strong root system can access moisture stored deeper in the soil, helping it stay greener for longer during dry weather.

Feed now for stronger summer growth

June is the ideal time to apply a slow-release fertiliser designed to support lawns through the summer months. Unlike fast-acting feeds that encourage sudden bursts of growth, slow-release fertilisers provide a steady supply of nutrients over several weeks.

This helps strengthen roots, improve colour and support healthy growth without placing unnecessary stress on the lawn. A well-fed lawn is also better able to cope with heat, foot traffic and changing weather conditions.

"Nutrition and hydration go hand in hand," explains Cheryl. "A lawn that has access to the nutrients it needs will naturally be more resilient when conditions become challenging."

Stop weeds stealing valuable moisture

Weeds compete directly with grass for water, nutrients and space. As temperatures increase and rainfall becomes less predictable, that competition can put additional pressure on lawns already trying to cope with summer conditions.

Tackling weeds now helps ensure that the resources available in the soil are going towards healthy grass growth rather than unwanted plants. Regular treatment during early summer can also prevent weeds from spreading and becoming harder to control later in the season.

Keep an eye out for signs of disease

Warm temperatures combined with occasional rainfall can create ideal conditions for certain lawn diseases to develop. Discoloured patches, thinning grass or unusual markings on the lawn surface can all indicate that a problem is starting to develop. Spotting issues early allows them to be treated before they spread and weaken the lawn further.

Did you know? A stressed lawn is often more vulnerable to disease, making preventative lawn care especially important as summer approaches.

Water deeply, not little and often

When watering becomes necessary, how you water matters just as much as how much water you apply. Frequent light watering only dampens the surface of the soil and encourages shallow root growth. This can leave grass more dependent on regular watering and less able to cope during hot weather.

Instead, occasional deep watering encourages roots to grow further into the soil where moisture remains available for longer. Watering early in the morning is also more effective, reducing evaporation and allowing the lawn to absorb moisture before temperatures rise.

Consider a wetting agent to improve water penetration

One of the most effective ways to support lawn hydration during the summer months is through the use of a wetting agent. These specialist treatments help water penetrate the soil more evenly, reducing surface runoff and allowing moisture to reach the root zone where it's needed most.

Over time, some soils can become water-repellent, particularly during prolonged dry spells, meaning that water struggles to soak in properly. Wetting agents work by improving the movement and distribution of water through the soil profile, helping lawns make better use of both rainfall and irrigation.

"Applying a wetting agent as part of a proactive lawn care programme can significantly improve moisture retention and help reduce the effects of drought stress," says Cheryl. "It's a simple step that can make a noticeable difference, especially during periods of hot, dry weather."

Did you know? A lawn treated with a wetting agent can often use available water more efficiently, helping to maintain greener, healthier grass for longer between watering sessions.

Raise the mower height as temperatures climb

One of the simplest ways to improve moisture retention during summer is to avoid cutting the lawn too short. Longer grass blades help shade the soil surface, reducing evaporation and protecting roots from excessive heat.

Keeping the mower blades slightly higher during summer also helps grass recover more quickly from periods of stress. For most domestic lawns, maintaining a height of around 4-5cm provides a good balance between appearance and resilience.

Prevention always beats cure

Many lawns can recover from drought stress, but recovery often takes time and requires significant intervention. Preparing your lawn before summer arrives is usually far easier than trying to rescue it once damage has occurred.

"June gives homeowners a fantastic opportunity to get ahead of summer stress – even after we’ve had a little heatwave already," says Cheryl. "A few simple lawn care jobs now can make a huge difference later in the season. By focusing on preventative care rather than waiting for problems to appear, you'll give your lawn the best possible chance of staying healthy, green and resilient throughout the summer."

Whether you're hosting family BBQs, enjoying evenings outdoors or simply taking pride in your garden, a little attention now can help ensure your lawn remains one of the standout features of your outdoor space all season long.
