Water is essential to the health of your lawn, but over or under watering can have a detrimental effect on its root system. Leaving the sprinkler on all night and soaking the lawn will drown the roots and provide the right conditions for the onset of disease. At the other end of the scale, watering too little and too often means bad news for lawns in the summer months, as the water will not penetrate deep enough. To keep your lawn healthy, green and strong, follow our tips and advice on how to water your lawn, the right way.
Get down to basics
As a general rule, water your lawn deeper, but less frequently. This means letting the water soak right down into the roots, around 6” deep. Water early in the morning while the sun is low and the lawn has the whole day to dry. Watering the lawn in the evening is one of the worst things you can do to your lawn, inviting unwelcome disease, fungus and mildew.
Check your sprinkler!
Sprinklers have a tendency to water unevenly, often completely missing large areas. A quick test to see if your sprinkler reaches all areas of your garden is to place plastic cups in various places around the lawn, turn on the sprinkler and see if the cups fill with water evenly, or not at all!
How often do I water?
Water new turf immediately after laying, and then twice a day for the first week, reducing to 2-3 times a week up to 4-6 weeks on. Mature turf should be watered around once a week, depending on rainfall. The most important point to remember is to water the roots and not just the grass blades above the soil line.
Do the water test
To check that water is penetrating deep into to the roots, push a screwdriver into the soil. If the screwdriver can be pushed in easily and comes out clean, the soil is moist underneath.
