Summer
Water the roots on a regular basis, this means no more than twice a week. This means no more than twice a week. It is actually preferable to water the lawn intensively only once a week (approx. 20 litres per m²). Watering more frequently is likely to "spoil" any lawn.
Either mulch mow the lawn continuously, or perform summer fertilisation. If you mulch or fertilise with a VIKING Multi-Mower™, you save having to fertilise during the summer.
During hot spells, allow the grass to grow longer (approx. 5 cm) and mow it during dull weather. Mow high "holiday lawns" in several stages, first at the highest cutting position, then at a slightly lower one. Dig out undesirable weeds from the lawn, repair damaged areas and resow any bare patches in the late summer so that the grass is able to take hold during the warm autumn days.
