How often you should water grass seed will depend on the weather conditions and climate where you live. Watering is an important part of establishing your new grass, but be careful not to overdo it.
‘Too much water can make it sit too wet and too dry won’t allow the seed to germinate,’ says Hedges Gower.
‘As a rough guide, a patch of around 3x3 feet (1x1 metre) should need about 15-30 seconds of water every 2-8 hours, depending on how warm the weather is.’
Always check to feel how damp the soil is before applying more water.
Once the grass is established, only water when needed and know when to water grass. 'Overwatering grass can lead to its demise and therefore grass should be watered during the cooler time periods and only once a week. When watering grass you are looking to water deeply to ensure there’s enough water to see through a drought, 'add the experts at Marshalls.
To encourage strong, vigorous growth, How Cobra, manufacturer of garden lawnmowers, recommends watering lawns early in the morning when heat is at a minimum to reduce the amount of evaporation. 'This allows water to penetrate the deeper into the root. An infrequent yet heavy dose of water is also recommended as it’s one of the most effective ways of stimulating stronger grass growth.'
Water butts are also a great way to collect and reuse any rainwater so that it can be saved to keep lawns hydrated and gardens watered as a sustainable garden idea.
