How often should I water new turf?
Quick answer
Keep new turf and the soil just underneath it moist until it roots in, which usually means watering daily or more in hot weather at first. Then water less often and more deeply so roots grow down. Follow your turf supplier's instructions, and check your water authority's rules, which may treat new turf differently.
Why this happens
New turf arrives with very short roots and no connection to your soil. Until it roots in, it depends entirely on you for water, and it can dry out fast, especially on a hot or windy day. Once it has rooted, the aim switches to encouraging deep roots.
The first stage: keep it moist
Water each section as soon as it’s laid, enough to wet the turf and the soil beneath it. For the first while, keep both evenly moist. Lift a corner to check: the soil underneath should feel moist, not soggy, and not dry. In hot weather that can mean watering daily or even more than once a day at first; in mild weather, less. Your turf supplier will usually give instructions for their product and season, so follow those.
The second stage: water less often, more deeply
When you tug a corner and it resists because roots have grown into the soil, start reducing how often you water while increasing how much you apply each time. Over the following weeks, move towards the deep, less frequent watering you’d use on an established lawn.
Rules, mowing and chemicals
Water authorities sometimes have special arrangements for new turf, and sometimes don’t. Check your water authority’s current rules before laying turf, especially in a dry spell. Wait until the turf has rooted firmly before the first mow, and check product labels before using any pre-emergent or herbicide on or near new turf.
Timing your new lawn
Warm-season turf roots in best when it’s actively growing, from spring into autumn. Laying in mid-summer is possible but needs the most water; laying in winter in cooler zones means slow rooting.
What you can do
Check for rootingCheck first
Gently tug a corner. When it resists because roots have grown into the soil, start reducing frequency.
Hold off on chemicalsCheck first
Check product labels before using pre-emergents or herbicides on new turf.
Water straight after laying
Soak the turf and the soil beneath it as soon as each section is laid.
Keep it moist while it roots
Check by lifting a corner: the soil underneath should be moist, not soggy. In hot or windy weather this may mean watering more than once a day at first.
Move to deep
Water less often but more deeply, so roots follow the water down.
What not to do
- Light sprinkles that wet the leaves but not the soil underneath.
- Keeping turf soggy for weeks, which rots roots.
- Walking on new turf before it has rooted.
