What Length to Mow the Lawn

Length to Mow the Lawn

The height at which the lawn is mowed needs careful thought.

It usually depends on the ability to leave enough grass in place to stay healthy while also cutting enough back to ensure the lawn looks neat and attractive.

A close cut is possible, but this is only practical when the optimum conditions are available, which can include:

  • Fertilizer
  • Rainfall (moderate)
  • Sunshine (moderate)
  • Warmth

This should help to increase the health of the lawn and make sure it is able to recover quickly after a low cut run.

If the lawn should experience conditions like constant drenching, cold, drought, heat, or prolonged stress, it will be necessary to leave the grass to grow longer before cutting to ensure it is able to survive.

The time of the season can help to determine the preferred length to cut the grass. Here is a general guideline to help calculate the different mowing heights:

  • Ornamental – An ornamental lawn is best cut at a length of 1-2 cm.
  • Low use – A lawn that gets low to minimal use can usually be left until it needs 2-4 cm cut
  • Heavy use – A heavy use lawn that gets a lot of foot traffic should be cut at 2.5-5 cm
  • Shady area – A lawn area that gets a lot of shade should get cut at 5-6 inches

Any lawn that gets a build-up of moss should be cut at least half-inch higher than the moss covering. Plus, for times of high stress, the lawn should be given extra time between the mowing sessions.

If the preferred height isn’t known, it makes sense to mow high to stay safe and avoid potential damage to the lawn in the future.

Working gently to control the lawn

A great way to manage the lawn care is to adjust the height of the mower blades in stages to avoid cutting back too much at once. Also, make sure to change the height of the blades throughout the different seasons. The blade should be positioned to match the conditions of the lawn, such as those relating to the length of the grass and whether it is dry or damp. Plus, the lawn that is quite dense can benefit from a cut at a higher length and reduced once more to complete a closer cut to achieve the desired look.

Aim to tall grass

It generally benefits to go with grass that is kept at the taller end of the recommended scale. This is certain to be beneficial during periods of drought. Many grasses, including the cool-season variety are better at growing when kept to a decent height. A similar principle will apply to the grass grown in the shady areas of the garden.

Mowing rules

To get the most out of the lawn mowing work make sure to mow when the grass is dry. Avoid cutting the grass shortly after a period of rainfall. Mow in the mornings when the weather is cooler. Make sure the blade is kept sharp. And aim to cut with alternating directions or patterns to prevent issues with compacted soil or ruts.
