The same scene repeats every summer in gardens and communities across the Costa del Sol: a lawn that was lush and green in spring starts turning yellow with the first heatwaves. And once dry patches are already visible, bringing it back costs far more than preventing it in the first place.
The good news is that, in most cases, a lawn doesn’t dry out simply because “it’s summer” —it’s because something in the irrigation, the soil or the maintenance isn’t properly adjusted to the heat. At Mantenimientos El Paraíso we see this issue every season, so here are the most common causes and how to act in time.
The most common causes of a dry lawn in summer
1. Insufficient or poorly scheduled watering
This is the most frequent cause. A timer that hasn’t been adjusted for summer heat, or watering that’s too short and too frequent and only wets the surface, leaves the roots without the water they actually need at depth.
2. Watering at the wrong time of day
Watering during the hottest hours of the day means much of the water is lost to evaporation before it reaches the roots. Early morning or late afternoon are far more effective times to water.
3. Mowing too short
Cutting the lawn too short in summer leaves it more exposed to direct sun and increases moisture loss from the soil. Keeping the grass slightly taller during the hot months helps protect the roots.
4. Compacted soil
Compacted soil prevents water from properly penetrating and reaching the roots, even if watering is sufficient. This is especially common in lawns with a lot of foot traffic.
5. Lack of proper fertilising
A lawn without the nutrients it needs enters summer weaker and less able to cope with heat stress, even if watering is well adjusted.
What to do before it’s too late
- Adjust automatic irrigation to summer’s actual needs, rather than leaving it on the spring schedule.
- Water in the early morning or late afternoon, never in full sun.
- Raise the mowing height during the hottest months.
- Aerate the soil if it’s compacted, to help water absorption.
- Apply the right fertiliser for the season before the heat sets in.
Acting as soon as the first yellow patches appear is key: a slightly stressed lawn can recover within a few weeks, while a completely dried-out lawn may need to be reseeded entirely.
Communities: why shared lawns suffer more
In shared green areas, several risk factors often combine at once: heavier foot traffic, irrigation programmed generically for the whole plot, and less chance of spotting early signs of drought in time. That’s why periodically adjusting irrigation and maintenance in these areas is especially important during the summer months.
The difference a professional service makes
Preventing a lawn from drying out isn’t about watering “more” —it’s about adjusting irrigation, mowing and fertilising to the exact time of year and soil type. Professional maintenance catches these imbalances before they become a visible problem.
At Mantenimientos El Paraíso, we adjust irrigation, mowing and fertilising for lawns season by season, in gardens and communities across the Costa del Sol, so summer heat doesn’t leave its mark on your garden.
