How to look after a newly laid lawn

Water, water, water

New turf has very short roots and dries out quickly. Water it thoroughly straight after laying and then regularly for the first two to three weeks — daily in warm or dry weather, and more often in a heatwave. Lift a corner: the soil underneath should be damp. Water early in the morning or in the evening.

If the turf starts to shrink and gaps appear at the joins, it needs more water.

Keep off while it roots

Keep foot traffic to a minimum for the first two to three weeks while the roots knit into the soil below. Gently tug a corner — once it resists, it is rooting. Keep pets and children off as much as you can; on some jobs we have lent customers temporary fencing to protect the new lawn.

The first mow

Mow for the first time once the grass is growing and the turf has rooted, usually after two to three weeks. Set the mower to its highest setting, make sure the blades are sharp, and never take off more than a third of the height at once. Lower the cut gradually over the following weeks.

Feeding

We lay our turf on quality topsoil with a starter fertiliser to support that crucial first growth. After about six to eight weeks, a light lawn feed suited to the season will keep it green and healthy.

Common problems

• Yellow or brown patches: usually too little water — increase watering.
• Edges lifting or gaps at joins: the turf is drying out.
• Soft, spongy areas: too much water or poor drainage — let it dry a little between waterings and get in touch if it stays boggy.

If you have any worries about your new lawn, give us a call — we are always happy to help.
