Answer
It depends on the season and temperature.
- Spring: 2 ½ inches (6 cm)
- Summer: 3 inches (8 cm)
- Heatwave/Drought: Do not mow
- Fall: 2 inches (5 cm), final cut at 1 ½ inches (4 cm)
Explanation
Adjusting the mowing height protects the lawn. In summer, a higher mowing height reduces heat stress and retains moisture. In autumn, mowing shorter prepares the grass for winter. Never mow too short, as it helps maintain healthy roots and optimizes the effectiveness of lawn treatments.
