Wait for the Roots to Anchor
It is incredibly tempting to run the lawnmower over your new turf as soon as it starts looking a bit shaggy. However, if the roots haven't fully knitted into the topsoil, the suction and pulling force of the mower blade will rip the delicate rolls right out of the dirt, ruining your perfect level.
The 'Tug Test'
Generally, you should wait at least 3 to 4 weeks before the first mow, depending on the season (summer rooting is faster than winter). To know for sure, perform the Tug Test: gently grab a handful of grass blades and pull straight up. If you feel resistance and the turf doesn't lift from the soil, it is securely anchored and ready to cut.
The Golden Rules for the First Mow
- Set the blades HIGH: Never scalp a new lawn. Set your mower to its absolute highest setting. You only want to take the very tips off the grass.
- Ensure the grass is DRY: Do not mow if the grass is wet from morning dew or rain, as this will tear the blades rather than cutting them cleanly.
- Use a sharp blade: A dull mower blade will bruise the grass, leaving yellow, frayed tips.
