A healthy lawn doesn't need to be perfect, but when grass starts turning yellow, becoming patchy or refusing to grow, it's usually a sign that something needs attention.
The good news is that many common lawn problems can be fixed without starting again. The important part is working out what's causing the problem before reaching for a bag of seed or fertiliser.
Even the best-kept lawns can run into problems. Bare patches appear, grass turns yellow, weeds and moss start taking over, or an area that once grew perfectly well suddenly becomes difficult to maintain.
The important thing is working out what's actually causing the problem. Throwing more grass seed onto a bare patch might provide a temporary improvement, but if the underlying issue is poor drainage, compacted soil, heavy wear or unsuitable growing conditions, there's a good chance the same problem will return.
A healthy lawn depends on more than the grass seed you choose. Soil condition, sunlight, drainage, nutrients, moisture and how the garden is used all affect how well grass grows.
A family lawn that regularly has children and pets running across it, for example, has very different demands from a lightly used front lawn. Areas beneath trees or alongside buildings may receive much less sunlight, while heavy clay soils can remain wet and compacted long after rainfall.
That's why there isn't one lawn care routine or grass seed mixture that's right for every garden.

Many of the most common lawn problems are symptoms of something happening underneath.
Moss can thrive where drainage is poor or grass is struggling in shade. Weeds can take advantage of thin areas in the lawn. Yellow or brown patches might be caused by drought, pet urine, nutrient problems or damage to the grass.
Once you've identified the likely cause, you can decide whether the lawn needs feeding, aerating, overseeding, repairing or simply a change in how it's being maintained.
In many cases, you won't need to replace the whole lawn. Improving the growing conditions and repairing the affected areas can be enough to bring an established lawn back into good condition.
Whether you're trying to repair a damaged lawn, establish stronger grass or work out why something isn't growing properly, you'll find practical lawn care advice and products below to help you choose the right approach.
A healthy green lawn is something most gardeners aspire to, and believe it or not, achieving it doesn't have to mean standing outside with a hose every evening. In fact, overwatering is one of the most common reasons lawns struggle during summer. Grass that receives too much water often develops shallow roots, making it less resilient when dry weather eventually arrives. With hosepipe bans becoming more common across the UK and water becoming an increasingly valuable resource, learning how to maintain a healthy lawn with less watering is better for both your garden and your wallet. The good news is that a resilient lawn isn't built through constant watering. It's built through encouraging strong roots and adapting your lawn care routine to suit the weather. Why Less Water Can Produce a Healthier Lawn It seems counterintuitive, but grass that receives unlimited water rarely develops a strong root system. When moisture is always available near the surface, roots have little reason to grow deeper into the soil. They just don't need to. The issue is that as soon as temperatures rise or watering stops, the lawn begins to struggle because it has no reserves to draw upon. By contrast, a lawn that receives deeper, less frequent watering gradually develops roots that search further into the soil. These lawns often remain greener for longer during dry weather because they're accessing moisture that's unavailable to shallow-rooted grass. The Royal Horticultural Society recommends watering thoroughly rather than little and often, allowing moisture to penetrate the soil where roots can benefit most. Their advice can be found at https://www.rhs.org.uk/lawns. Not Every Garden Needs the Same Amount of Water One of the biggest mistakes gardeners make is following a fixed watering schedule. A lawn in full sun from morning until evening behaves very differently to one that's shaded for much of the day. Even within the same garden, conditions can vary considerably. Imagine a south-facing garden where the lawn wraps around the side of the house. The front section receives uninterrupted sunshine throughout the afternoon, while the side lawn is shaded by the building from lunchtime onwards. Although they're only metres apart, the sunny section may need watering days before the shaded area. Soil type has an equally important role. Light sandy soils drain rapidly and dry out quickly after rainfall, whereas clay soils retain moisture for much longer. If you've struggled to establish grass on heavy ground, improving the soil may be just as important as choosing the right seed. Our article on growing grass successfully in clay soil explains how different soils influence lawn health. Choose a Grass Seed That Matches Your Lifestyle Some lawns naturally require less water than others. If you prefer a tidy lawn that doesn't need constant mowing or irrigation, choosing the right seed mixture from the beginning can significantly reduce maintenance. Our Fine Growing Low Maintenance Lawn Seed has been developed for gardeners looking for an attractive lawn that requires less intervention throughout the year. For gardens used heavily by children, pets and entertaining, Hard Wearing Lawn Seed provides greater durability while still producing a healthy lawn that copes well once established. If you're starting from scratch, Fast Growing Lawn Seed establishes quickly, helping young plants develop before periods of hot weather arrive. You can compare every option in our lawn seed collection. Let Your Grass Grow a Little Longer Many people cut their lawn as short as possible, believing it will stay tidy for longer. Unfortunately, this usually has the opposite effect during summer. Short grass exposes more soil to direct sunlight, allowing moisture to evaporate much faster. Longer grass shades the soil surface, helping retain moisture while encouraging stronger roots beneath the surface. This doesn't mean allowing your lawn to become overgrown. Simply raising your mower by one setting during dry weather can make a noticeable difference. The Royal Horticultural Society also recommends avoiding mowing during prolonged hot spells unless absolutely necessary, as cutting stressed grass places additional pressure on the plant. Water Smarter, Not More Often When lawns begin turning brown, the instinct is often to water every evening. In reality, this creates a cycle where the lawn becomes increasingly dependent on regular watering. Instead, aim to water deeply so moisture reaches well below the surface. This encourages roots to grow downwards rather than remaining close to the top of the soil. Early morning is generally the best time to water, as cooler temperatures reduce evaporation and allow more moisture to reach the roots. This approach is especially important while establishing a new lawn. Knowing how often newly sown grass should be watered can dramatically improve germination without wasting water. Feed Your Lawn at the Right Time Healthy grass naturally copes with drought better than weak grass. Applying Pre Seed Fertiliser 6-9-6 before sowing encourages stronger early root development, while products from our lawn fertiliser range help maintain healthy growth throughout the growing season. Avoid applying fertiliser during extreme heat unless rain is forecast or watering is available. Feeding stressed grass can do more harm than good if the nutrients cannot be absorbed properly. Avoiding common feeding mistakes can make just as much difference as choosing the right fertiliser in the first place. Brown Doesn't Always Mean Dead One of the biggest causes of unnecessary watering is panic. As soon as lawns begin losing their green colour, many gardeners assume the grass is dying. In reality, grass naturally enters dormancy during prolonged dry weather. Growth slows, the leaves lose their colour and the lawn conserves energy until conditions improve. Before deciding to reseed or dramatically increase watering, it's worth understanding whether drought-damaged grass can recover. In many cases, rainfall is all that's needed for the lawn to green up again. Building a Lawn That's Naturally More Resilient Keeping a lawn green with less water isn't about finding a miracle product. It's about creating the right conditions for healthy grass from the beginning. Choose a grass seed suited to your garden and how it's used. Water deeply rather than frequently. Raise your mowing height during summer. Feed the lawn when conditions are suitable. Accept that some slowing of growth during hot weather is perfectly natural. These simple habits encourage stronger roots, healthier soil and a lawn that's much better prepared for future summers. As UK summers continue to become warmer and drier, these small changes can make a significant difference, helping your lawn remain healthier while using considerably less water throughout the season.
For many UK gardeners, summer used to mean occasional watering and a few weeks of slower lawn growth. Today, it's increasingly common to experience prolonged dry spells, hosepipe bans and weeks without meaningful rainfall. It's a lawn's worst nightmare. Worse still, it feels like it happens a few times per year in recent years. A lawn that looked lush in May can be brown by July, leaving many people wondering whether they've chosen the wrong grass seed or simply been unlucky with the weather. The truth is that some grass varieties cope with dry conditions far better than others. Choosing the right seed won't guarantee a green lawn throughout every heatwave, but it can dramatically improve your lawn's ability to withstand drought and recover when the rain eventually returns. If your lawn regularly struggles through hot summers, changing the seed mixture is often one of the most effective long-term improvements you can make. What Makes Grass Drought Tolerant? Grass survives dry weather by doing two things: developing roots that can reach moisture deeper in the soil and reducing water loss through its leaves. Some varieties naturally grow deeper root systems than others, allowing them to continue drawing moisture long after the surface has dried out. Others grow more slowly, requiring less water to maintain healthy growth. Understanding how grass grows helps explain why healthy roots are every bit as important as healthy leaves. Your Garden Plays a Bigger Role Than You Think Many people assume every lawn experiences the same conditions, but even within a single garden there can be significant differences. Imagine an L-shaped garden where one section receives sunshine from sunrise until late afternoon, while the other sits beside the house and falls into shade by lunchtime. The sunny section may dry out days before the shaded area, despite both being planted with the same seed. The same applies to soil. A sandy garden in Norfolk behaves very differently to a heavy clay garden in Yorkshire. Sandy soils drain quickly, making them more vulnerable during prolonged dry weather, while clay retains moisture for longer but can bake hard once it eventually dries. If your garden has particularly heavy ground, choosing the right seed is only part of the solution. Improving the soil and selecting a mixture suited to those conditions often produces much better results, particularly if you've struggled with grass growing in clay soil before. Choosing the Best Grass Seed The best grass seed depends on how your lawn is used as much as the weather itself. If your priority is reducing maintenance while keeping a tidy lawn throughout summer, Fine Growing Low Maintenance Lawn Seed is an excellent choice. Its slower-growing grasses generally require less mowing and often cope better with dry conditions than vigorous, fast-growing lawns. For family gardens that see regular use from children, dogs or entertaining, Hard Wearing Lawn Seed offers an excellent balance between durability and drought tolerance once established. If you're creating a completely new lawn during late spring or early autumn, Fast Growing Lawn Seed establishes quickly, helping young plants develop stronger roots before the hottest weather arrives. Our complete range of lawn seed includes mixtures suitable for every type of garden, whether you're creating a family lawn or replacing one that's repeatedly damaged by dry summers. Don't Just Think About the Grass One of the biggest mistakes gardeners make is assuming grass seed alone will solve drought problems. Imagine two identical lawns seeded on the same day. The first lawn is mown very short every weekend, watered lightly every evening and receives heavy foot traffic throughout the summer. The second is allowed to grow slightly longer, watered deeply once or twice each week and given time to establish properly during spring. By August, the difference is usually obvious. The second lawn has developed deeper roots, retains moisture for longer and generally recovers much more quickly after hot weather. The Royal Horticultural Society recommends raising mowing heights during dry weather because longer grass naturally shades the soil, reducing evaporation and helping roots remain cooler. You can read more in their lawn care advice: https://www.rhs.org.uk/lawns. Watering Matters More Than You Think When rain disappears for several weeks, watering becomes a balancing act. Many gardeners reach for the hose every evening, applying just enough water to dampen the surface. Unfortunately, this often encourages shallow root growth, making the lawn even more dependent on frequent watering. Less frequent but deeper watering encourages roots to search further into the soil, producing a more resilient lawn over time. This becomes even more important while establishing a new lawn. Knowing how often newly sown grass should be watered can make the difference between an even, healthy lawn and one filled with bare patches. Applying Pre Seed Fertiliser 6-9-6 before sowing also encourages stronger early root development, while our wider range of lawn fertilisers helps maintain healthy growth throughout the year. Is a Brown Lawn Dead? One of the biggest misconceptions about summer lawns is that brown grass has died. In reality, many lawns simply become dormant during prolonged drought. Growth slows dramatically, the leaves lose their colour and the lawn appears lifeless while the roots wait for cooler, wetter conditions. Many recover surprisingly quickly after sustained rainfall returns. Before reaching for more grass seed, it's worth understanding whether drought-damaged grass can recover naturally. Quite often, patience is all that's required. Preparing for Future Summers Long-range climate projections suggest that hotter, drier summers are likely to become more common across much of the UK. The Met Office has published research showing an increase in the frequency and intensity of heatwaves, making drought resilience an increasingly important consideration for gardeners: https://www.metoffice.gov.uk/weather/climate-change Rather than repeatedly repairing damaged lawns every year, it's worth thinking about prevention. Choose a grass seed suited to your garden conditions rather than simply the cheapest available. Encourage deep roots through sensible watering and mowing practices. Repair worn areas during autumn when conditions are naturally more favourable. Improve soil health before sowing by preparing the seedbed properly. A lawn that survives dry summers isn't usually the result of luck. It's the result of choosing the right grass seed, encouraging healthy root development and adapting your maintenance routine to changing weather conditions. Whether your garden is exposed to full sun all day or only struggles during occasional heatwaves, selecting a more suitable seed mixture now can reduce watering, improve recovery after drought and help create a lawn that remains healthier throughout the summer for years to come.
A spell of warm weather is usually good news for anyone sowing a new lawn. Warm soil encourages germination and helps young grass establish quickly. However, when temperatures climb into the high twenties or beyond and rainfall disappears for days or weeks, those same conditions can quickly turn against you. Many gardeners assume grass seed has been "burnt" by the sun after a heatwave, but that's rarely what's happened. The seed itself is surprisingly resilient. The real problem is what happens before and during germination. Understanding how heat affects grass seed can help you decide whether to keep watering, start again, or simply wait for cooler weather. Can Grass Seed Survive Extreme Heat? Simply put, yes, grass seed can survive a heatwave, but only if it has enough moisture available. Before germination, grass seed is essentially dormant. It can sit in dry soil for some time without being damaged by sunlight alone. Once it absorbs water and the germination process begins, the situation changes dramatically. A newly germinating seed depends on constant moisture. Constant. If the soil dries out completely during this stage, the young plant may never recover. This is why two neighbours can sow grass on the same weekend and experience completely different results after a hot spell. One lawn thrives because it receives regular watering, while the other struggles because the soil repeatedly dries out between waterings. Understanding How Long It Takes a Newly Seeded Lawn to Grow helps explain why the first couple of weeks are so important. What Happens During a Heatwave? High temperatures affect much more than the grass seed itself. Moisture evaporates far more quickly from the soil surface, particularly on sunny days with strong winds. Dark soils absorb additional heat, while newly prepared seedbeds have very little shade to protect them. The result is often a cycle where the soil becomes damp after watering before drying out completely a few hours later. If this happens repeatedly, germination becomes patchy. Some seeds establish successfully while others fail altogether, leaving thin areas across the lawn. This is one reason gardeners often mistake heat damage for poor-quality seed. Real Garden Examples Imagine you've just seeded a south-facing garden in early July. The lawn receives uninterrupted sunshine from mid-morning until early evening, and temperatures remain above 28°C for several consecutive days. Even if you watered thoroughly on the day you sowed the seed, the surface could become completely dry before the following morning. Without regular watering, germination becomes inconsistent and bare patches begin appearing. Now compare that with a north-facing garden where neighbouring houses provide afternoon shade. Although the air temperature is identical, the soil retains moisture much longer. The grass establishes more evenly because it spends less time drying out. Garden shape can make a difference too. An L-shaped garden often contains one sheltered corner that remains noticeably cooler than the rest of the lawn. It's common to see grass thriving in that section while exposed areas struggle. Can Established Grass Survive? Established lawns cope with heat much better than newly sown seed. Healthy grass naturally slows its growth during prolonged hot weather and may even turn brown. Although it looks dead, it's often entering a dormant state to conserve water. Many lawns recover perfectly once rainfall returns. If you're wondering whether your lawn has reached that point, Can Dead Grass Recover After Drought? explains how to tell the difference between dormant grass and grass that has genuinely died. Is It Better to Wait? Sometimes, yes. If a prolonged heatwave is forecast and regular watering isn't practical (especially if you have a holiday booked), delaying sowing for a week or two can produce much better results. Grass seed doesn't have to be sown the moment you've prepared the ground. Waiting for cooler temperatures or a period of reliable rainfall often leads to faster establishment with much less effort. Helping Grass Seed Through Hot Weather If you do decide to sow during a heatwave, success depends on maintaining consistent soil moisture rather than applying large amounts of water once each day. The most effective approach is to: Water lightly whenever the soil surface begins drying. Sow early in the morning or later in the evening rather than during the hottest part of the day. Apply Pre Seed Fertiliser 6-9-6 before sowing to encourage strong early root development. Choose a quality seed mixture such as Fast Growing Lawn Seed to reduce the time seed remains vulnerable. Keep foot traffic to an absolute minimum while seedlings establish. Maintaining moisture is far more important than watering heavily. How Often Should You Water Grass Seed? explains why little and often is usually the better approach. Choosing the Right Grass Seed Some lawns naturally cope with hot, dry conditions better than others. If your garden regularly experiences long periods of sunshine, choosing a suitable seed mixture from the beginning can reduce future maintenance. Our Low Maintenance Lawn Seed is designed for gardeners looking for a lawn that requires less frequent mowing and generally copes better with challenging conditions, while Hard Wearing Lawn Seed is ideal where children, pets and everyday use place additional stress on the lawn. You can compare every mixture in our Lawn Seed collection. If hot weather is unavoidable, regular watering, good soil preparation and choosing the right seed mixture will give your lawn the best chance of success. If not, waiting until temperatures become more favourable is often the smarter decision. Either way, a little patience is usually rewarded with a thicker, healthier lawn that will cope much better with future summers.
Look at the shape, location and colour of the patches. Localised damage can be caused by dog urine, drought, heavy wear, disease or accidental application of lawn products. If the same areas repeatedly die, check the underlying soil and drainage rather than continually reseeding them.
You can, but germination is generally better if you prepare the area first. Remove dead grass and debris, loosen the upper layer of soil, sow the seed and lightly rake it in to improve seed-to-soil contact. Keep the area moist while the new grass establishes.
Yes. More seed doesn't automatically produce a better lawn. Excessively dense seedlings compete for water, nutrients and space, which can result in weaker establishment. Follow the recommended sowing rate for the mixture you're using.
Spring and early autumn generally provide the most favourable combination of soil warmth and moisture. Exact timing depends on the weather rather than the calendar, as grass seed needs sufficiently warm soil and reliable moisture to germinate successfully.
It depends on why it's struggling. Nutrient-poor grass can respond very well to an appropriate lawn feed, but fertiliser won't correct waterlogging, severe compaction or unsuitable growing conditions. Diagnose the likely cause first rather than assuming every unhealthy lawn needs feeding.
Some grass varieties can begin germinating relatively quickly in good conditions, while others take considerably longer. Temperature and moisture make a major difference, so don't assume seed has failed simply because nothing has appeared after a few days.
