GreenThumb Lawn Watering

Just like any living organism, grass needs water to survive. Watering your lawn promotes growth, helping to develop roots, stems, and leaves leading to a thicker and lusher lawn. Without enough water, grass can suffer from drought stress, which can lead to browning, wilting, and even death of the grass plants. Watering your lawn also facilitates the uptake of nutrients from the soil into the grass roots, which is essential for the overall health and vigour of the lawn.

  • Watered lawn compared to dry lawn

    Don’t wait until the soil is too dry before watering as this can make the soil difficult to re-wet. When your lawn is starting to suffer from lack of water the grass will start losing its colour very quickly and turn yellow or brown, this is your sign that your lawn needs watering.

  • Watering Grass with Sprinkler

    Ensure you apply an adequate amount of water per application, aiming to wet to a depth of at least some 50mm. A minimum application rate of 10 -11 litres per m² is generally suggested, although this will depend upon the soil type and its filtration potential. The average tap varies per water pressure, locally it is 11.5 litres per minute.

  • Hydrated, well watered lawn

    The lawn should be allowed to dry before further watering takes place, as this will encourage deeper rooting of the grass and reduce the potential for disease attack. As a guide, during the main part of the growing season (March to September) we would advise watering on at least 3 occasions per week (when there is no rainfall).

  • watering lawn at sunrise

    The most efficient time to water is between sunset and sunrise due to less evaporation, less wind, and lower temperatures. Early morning is the next most efficient time to irrigate; watering in the middle of the day is not advised due to the amount of evaporation taking place at this point in the day.

  • mowing your lawn and watering

    Avoid cutting the lawn in high drought situations unless regular watering is taking place, cutting lawns will increase demand for water which if not there will increase stress on the lawn.

  • How often you should water grass

    Improving the efficiency of this water management programme is to have the Oasis Treatment applied to the lawn. This will improve the water movement from the surface deeper into the root system and maintains a good environment for the grass to survive through the dry period.

Drought Stress in lawns

Drought stress occurs when the grass is not receiving an adequate amount of water to sustain its health and growth. This condition arises during periods of extended dry weather or insufficient watering.

If your lawn is suffering from drought stress grass blades may appear limp, folded, or curled as a result of water loss and dehydration. They may also turn yellow, brown, or straw-like in colour as it becomes dormant in an attempt to conserve moisture. Grass density may also decrease as individual blades die off due to lack of water, resulting in sparse areas or patches in the lawn. Grass growth will also slow down or cease altogether as the plant redirects its energy to essential functions such as root survival.

Drought-stressed lawns are more vulnerable to pests and diseases, as weakened grass plants are less able to defend themselves against these threats.

Dy, yellow, brown brittle lawn

If your lawn is suffering from drought stress we recommend:

  • Giving your lawn a deep watering to replenish moisture in the soil.
  • Avoid mowing your lawn as much as possible. Mowing can stress the grass further and increase water loss through evaporation.
  • If possible, provide temporary shade for your lawn using shade cloth or temporary structures to reduce water loss through evaporation and protect the grass from excessive heat.

By following these steps, you can help your lawn recover from drought stress and promote its overall health and resilience to future dry periods.

Frequently Asked Questions

Will my lawn recover without watering?

In most instances it will, however there are times when after the grass has become dormant and the dry weather continues with high temperatures and bright sunshine, this could cause several grass plants to die and recovery will not be possible, your lawn when it finally returns will have lots of wild grass

My lawn is on sandysoil, why doesn’t it hold water?

Sandy soil does dry out extremely quickly. We would recommend our Oasis Treatment as this holds moisture near the surface and helps the lawn to utilise any water that it does receive, this does not replace regular watering but does make use of any available moisture.

We have had rain, will my lawn survive?

Rainfall is the best form of watering a lawn can receive; it plays a huge part in the recovery of the lawn but cannot always be relied upon. A small shower is good but long steady rain over several hours is much better as it is the amount of rainfall your lawn receives which will determine if your lawn will survive.

I am on a meter and cannot afford to water the lawn, what should I do?

The question to ask yourself is how much would it cost to replace the lawn? Also, you may think you need to water for hours, this is not the case, and our Oasis Treatment (water conserver) reduces the amount of water your lawn needs as it significantly improves the movement of any moisture through the soil to the root zone where it’s required, rather than draining right through or sitting on top, therefore allowing you to keep your lawn at very little cost.
