How to water a lawn

Sounds like a simple task doesn’t it? But, if you get it wrong your lawn will struggle to survive and thrive. Both under-watering and over-watering can be damaging to your lawn so, how do you water a lawn correctly?

Overall, lawns only need around 2.5cms of water per week to stay in good condition. But, this doesn’t, and shouldn’t, all come from your hose, sprinkler or watering system. Take into consideration any natural rainfall your lawn has received in the past seven days, and the rain on the forecast. Have a look at your lawn – if the blades of the grass plants are yellowing, wilting or browning and there’s no rain on the horizon then you’re right to give your lawn a drink.

Determining how long it takes to apply 2.5cms of water to your lawn is relatively easy. Take a can or container and place it in the middle of your lawn – hand-hose, turn on the sprinkler or watering system and start a timer. Stop the timer when there is 2.5cms of water in the can/container and you’ll know how long to water for your lawn to receive the right amount of water.

Timing is everything. So, you already know about considering the timing of rainfall but there’s a little more to it. Aim to water your lawn early in the morning. If you water later in the day, the moisture can be lost through evaporation. If you water at night, the moisture can sit on the leaves and increase the risk of disease.

And our final tip on how to water a lawn is a big one. You should water your lawn less frequently but more deeply. This practice will encourage a more drought resistant lawn and a deeper, stronger root system.

Following this basic tips will ensure a stronger, healthier, greener lawn all year long. If you need additional lawn watering advice just contact the team at Harden Park Lawns today.
