Hello, We're the Hedge Cutting Staffordshire team, a professional gardener based in Staffordshire. If your lawn is looking patchy and uneven, you're in the right place. Let's delve into the causes and solutions for this common issue.

Quick Answer

Lawn scalping is often caused by mowing too low, uneven ground, or dull mower blades. Fix it by adjusting your mower height, levelling your lawn, and sharpening the blades.

Understanding Lawn Scalping

Scalping occurs when the mower cuts too close to the soil, removing almost all the grass blades. This can expose the grass crowns and soil, leading to brown patches. In the Midlands, especially with our variable weather, maintaining the right grass height is crucial.

Common Causes of Scalping

Mowing Too Low

One of the primary causes is setting your mower too low. Many people mistakenly believe that cutting the grass shorter means mowing less often. However, this can damage the grass.

Uneven Ground

Lawns in Staffordshire often suffer from bumps and dips due to natural settling or mole activity. These uneven surfaces can cause the mower to scalp certain areas.

Dull Mower Blades

Using dull blades tears the grass rather than cutting it cleanly, which can lead to scalping. It’s essential to maintain sharp blades for a clean cut.

How to Fix and Prevent Lawn Scalping

  • Adjust your mower height to at least 2.5-3.5 cm, especially during cooler months.
  • Regularly check and sharpen your mower blades.
  • Level your lawn by filling in low spots with topdressing soil.

To keep your lawn in top shape throughout the year, follow this simple monthly guide:

Month Task Details
