Try not to remove more than one third of the grass length on any one occasion.

A healthy lawn can survive an occasional close cut. Repeated close mowing produces a brown lawn and has several harmful side effects, including:

• Injury to the crown, where new growth generates and nutrients are stored.
• Reduction of the surface area of the blade, making the blade surface insufficient to produce food through photosynthesis.
• Increased vulnerability to pests and disease.
• An increase in the sunlight reaching weed seeds, allowing them to germinate.
• Risk of soil compaction.
