Heat Stress
Why it’s important to lay turf as soon as possible after delivery
Once you’ve ordered your turf and been given a delivery date, you need to ensure that it can be laid in a timely manner.
If you leave the rolls of turf for too long, there’s a good chance that you’ll find yellow or dry patches. This can be down to heat stress, which can affect the quality and appearance of turf before it’s laid, especially during warmer months.
So what is heat stress, why does it happen and how can you prevent it?
What is heat stress?
Heat stress occurs when turf is exposed to high temperatures after being harvested and rolled. Turf rolls are stacked for transport to enable efficient delivery. However, rolling limits airflow between layers. In warmer weather this can lead to heat build-up.
It’s important to remember that freshly cut turf is a living plant system that continues to release energy even when rolled. This produces heat and without enough ventilation, that heat becomes trapped, causing the turf to overheat, dry out, and even deteriorate.
Why does it happen?
Heat stress is most common during late spring and summer when ambient temperatures are higher.
- Delays in laying the turf after delivery
- Long storage times, particularly if rolls are kept in a hot van or on-site without shade
- Poor handling, such as stacking turf in direct sunlight or failing to unroll it promptly
- Lack of moisture, which makes grass more vulnerable to damage
How to prevent heat stress
Turf is at its healthiest immediately after harvesting. Once it has been delivered:
Lay turf asap
If possible, lay your turf within 24 hours of delivery or even on the same day, especially in warm weather.
Keep turf cool
If you can’t lay the turf immediately, store the rolls in a cool, shaded area. Don’t stack them too high and keep the stack slightly loose to help the flow of air.
Watering
Water the soil before you lay the turf. Once it’s laid, thoroughly soak the lawn – this helps the turf recover from any stress and encourages root establishment.
Order from an experienced supplier
Turf grown and harvested by an experienced supplier will be healthy, which means it is less prone to heat stress. Reliable growers time their harvesting carefully and deliver turf quickly to minimise deterioration. An experienced turf grower will:
- Cut turf fresh to order
- Handle it carefully
- Minimise time between cutting and delivery
- Provide advice on installation and aftercare
- Understand how to manage turf in different seasons
Choosing a reputable, local supplier ensures you receive turf that’s suited to local conditions and is far less likely to suffer from heat-related damage.
