How To Water Your Lawn

Grass is a plant and water is essential for its survival.


If your lawn is brown and patchy during the summer then the most likely cause is dryness. If your lawn is dry, then watering will certainly help to maintain a good colour and appearance. If you do water your lawn then do so in the evenings/early mornings (watering during bright sunlight can scorch grass) and aim to do this heavily 2-3 times per week.


You are aiming to get the water into the root zone as this will have the most impact, a couple of heavy soakings with a sprinkler for 1.5-2 hours at a time (in each position required to cover the lawn) should achieve this. You can determine whether the water is reaching the lawn roots by applying the sprinkler then leaving alone for 24 hours before digging up a small core of turf and soil to see how far down the soil the water has reached.


If the water hasn’t reached the desired depth then extend the sprinkling time next time you water. Do not use a hose or watering can, as this will not put on enough water to reach roots.


Watering daily for shorter durations does not have the same impact and can encourage turf disease such as Red Thread as the sward often remains damp and humid as it doesn’t get time to dry out in between watering and the water is unlikely to drain right down in to the root zone where it is needed. Watering is especially important for newly laid turf or areas recently seeded where the root depth may be quite shallow.


In Summary:

  • Water early in the morning or in the evening.
  • Water heavily, 2-3 times per week. Applying 25mm of Water.
  • Water when the soil becomes dry, between May-September.


Avoid Watering with a ‘little and often’ approach.
