The best advice for mowing a lawn is little and often, for the last few cuts of the year gradually raise the height of the blades and we recommend that the cuttings should be removed.
First growth:
When grass is 5-8cm (2-3 inches) high, cut for the first time. Trim lightly and gradually lower blades to an ideal cutting height of 25mm (1 inch).
Subsequent cuts:
Mow regularly but try not to remove more than a third of the growth at any one time
For a new Non-Ryegrass Lawn
First growth:
When grass is 5-8cm (2-3 inches) high, cut for the first time. Trim lightly and gradually lower blades to an ideal cutting height of 13mm (½ inch)
Subsequent cuts:
Mow regularly but try not to remove more than a third of the growth at any one time.
Do not mow whilst the grass is damp.
If the mower doesn’t have a roller, then the lawn can be rolled after this first cut. This will encourage lateral growth thus making a more closely knit turf.
