The ground is prepared, the weather is fair and you're ready to lay turf. But how much turf do you actually need to order? Calculate the total area of the patch where you are laying and assume one turf per square metre. Allow an extra 10% for shrinkage and wastage. It is wise to order a little more than is needed, as it may be impossible to obtain turf the same day as it is usually cut to order. Never order fresh turf before it is needed - it has a short shelf life, especially during the summer months. If the weather is hot, place the turf in the shade until needed and lay within 24 hours of receipt for best results. Water the turf after laying - it must not be allowed to dry out.
