Watering, along with mowing, are without doubt the two most important maintenance tasks for maintaining a healthy lawn. Just like any other plant, the grass plant needs water to survive and thrive. However, there is an art to watering your lawn – find out all about it below.
Why water your lawn
Grass is a very resilient, hardy plant. If you decide not to water it, its defense mechanism is to turn brown and dormant during the summer. In most cases, lawns will recover when moisture becomes naturally available again in the autumn.
However, if you want to keep your lawn looking lush and green all year round, it’s a must that the sprinkler comes out!
When to water your lawn
We recommend to begin watering your lawn when the soil at the base of the grass plants begin to turn noticeably dry. This might be as early as late-April or May. Ideally, you will start watering before the soil becomes fully dry. This is the best method, as trying to re-wet completely dry soils is very tricky during the summer months.
There is not particularly a bad time to water your lawn during the day. After all, some water is better than no water. However, we do advise to avoid watering during the middle of the day especially if conditions are very warm as much of the water you apply will evaporate before it has the chance to soak in.
Watering early in the morning or late evening is best as this allows the lawn and soil to soak up as much water as possible.
How much water your lawn needs
Watering an established lawn should be done in a way that replicates a heavy downpour. We recommend watering your lawn two or three times per week during periods of minimal rainfall, applying 20-25mm of water across the entire lawn area at a time. This will allow the water to soak deep into the soil to the root zone where it will have the best effect and encourage deep rooting.
If you water with a little and often approach, this could actually have a detrimental effect on your lawn. Little and often will encourage the roots to stay closer to the surface in search for moisture, which in turn makes the lawn more susceptible to drought.
To record the amount of water you’re applying, a good trick is to place a rain gauge or empty jam jar within range of your sprinkler. Once the gauge or jar has filled up to the required amount (20-25mm), you know you can turn the sprinkler off.
- Begin watering before the soil fully dries out.
- Apply 20-25mm of water at a time.
- Aim to water first thing in the morning or late evening.
