It might seem simple to pull the mower out of the shed every few weeks and give the lawn a once over. However, with a little care and planning you can ensure that your are mowing correctly so that your lawn thrives and stays green and healthy.

How to mow your lawn

  • Mow in the cool of the day and don’t mow if hot weather is expected.
  • Only take off 1/3 of the leaf length, as most of the green is in the top of the plant and your lawn gains its sun protection from the leaf area.
  • Always use sharp mower blades that cut rather than tear the grass.
  • Let grass dry out a bit before mowing to avoid leaving tracks in your lawn.

How often should you mow

There is no definitive rule as to how often you should mow your lawn. It really depends on where you are located, the season, what lawn variety you have and your preference of lawn height and look.

A good rule of thumb is every 1-2 weeks in Spring / Summer and every 2-5 weeks in Autumn / Winter.

Aeration and dethatching

Aeration

As your lawn gets older, the soil will often get compacted.  Your lawn will benefit from aeration to allow water & air infiltration.  This is best done in the spring/summer months with a mechanical aerator or pitch fork.

Dethatching

Thatch is the organic matter that builds up above the soil line and often inhibits water and fertiliser absorption.  Dethatching is needed periodically to older lawns.  You can hire a dethatching machine or alternatively mow (scalp) your lawn low down. This will promote root growth and allow water penetration.  If you mow low once a year you can help prevent thatch build up from years of growth.
