Check when and how much to water your lawn and garden

Should I water?

Check the weather forecast. If rain is forecast, hold off on watering your garden. If you have an automatic sprinkler system, make sure it has a moisture sensor to avoid automatically watering when the garden has received enough rainfall.

When should I water?

If you do need to water, try to do this before 10am and after 4pm to reduce the amount of water lost to evaporation.

How much to water?

Instead of watering the entire garden, just water the plants that need it. Many plants are much tougher than you think and will go for quite long periods without additional watering. This also has the effect of training your plants to be more resilient. Less frequent watering forces roots down to find water, making the plants less reliant on surface water and better able to cope with hot, dry days.

Experiment with watering less to understand the impact on the plant and adjust your watering frequency and amount to suit.

Think about what this means for manual and automatic watering systems. Does your entire garden need watering? Can you zone plants that need more or less water into areas so you can focus watering on the areas that really need it?

Watering lawns

The accepted wisdom is you should not water too often. Giving the lawn a proper drink, less often, encourages deeper root growth and means your grass will be more able to withstand heat stress and dry periods.

Did you know that your lawn mowing practices affect how much water your lawn needs? The golden rule is never cut your lawn by more than a third of the grass length. Some people like to leave the clippings on the lawn to form a mini-mulch and retain moisture longer.
