Why Should My Lawn Be Scarified?

If your lawn is not Scarified on a regular basis it can develop an unwanted amount of Thatch, which is a layer of decaying organic matter that lies on top of your lawn’s root zone. This will be an issue for your lawn as it will reduce the available moisture and nutrients to your lawn’s root zone, resulting in weak growth and poor looking lawn as it will become thin and patchy and eventually die off. However, a moderate level of thatch (approx ½ inch or less) can be beneficial to your lawn as it will provide a home for the beneficial microorganisms that your lawn needs.

Every lawn is different and many factors will depend on how often your lawn should be scarified. For example if your lawn is made up of fine fescue grass plants it is likely to develop a build up thatch much quicker than a coarse rye grass lawn and will require a more regular scarification to keep it in great condition. Another factor is the activity of bacteria in your lawn’s soil and how your lawn is mowed will contribute to how quickly thatch builds up. Scarification is an important part of a lawn care programme and we would advise Scarification at least once every other year.

So what is Lawn Scarification?why should my lawn be scarified


Scarifying is a process best described as a powerful mechanical raking of the lawn. The Scarifier is a machine that drives a series of very sharp blades into the Thatch layer of the lawn and removes it.

Scarification is also beneficial in that it will provide an element of Aeration, which will improve the drainage of lawns and make lawns more disease tolerant, as well as reducing the sponginess of lawns if that is already an issue.

As with all of our Services Lawnscience will only use the very best professional lawn care machines. You can feel confident that your lawn will be in great hands.


Once the Scarifier has completed it’s work, the Thatch will be moved to the surface of the lawn and can then be raked out and disposed or composted. Lawn Scarification

It is very important to choose the correct time to Scarify your lawn


Scarification should be carried out when the grass is actively growing in the Spring time or Autumn. This will allow the lawn time to recover from what can be a stressful process for your lawn. If your lawn is too dry, wet, frozen or covered in snow it is the wrong time to carry out a Scarification. If your lawn is scarified at the wrong time it will look very poor for weeks afterwards and you could be damaging healthy grass.

Preparation and good planning is an important part of great lawn care. Before you carry out a Scarification of your lawn it will need to be short and so you should mow the height down gradually about a week or two before. This will reduce any shock to the grass and allow air to get into the grass plants helping dry the grass.

It is a good idea to remove any weeds from your lawn about a week before Scarification is carried out. Although scarifying can help control some creeping weeds, it is an ideal opportunity to apply weed killer at this time to get on top of weed control.

The day before your lawn gets scarified it should be mowed as close as possible without scalping (approx 1 inch).  Long grass will just create resistance to the Scarifier.

A great lawn care company will only carry out lawn Scarification at the RIGHT time.


Scarification can also provide a great opportunity to invigorate your lawn. New grass seed can then be over-seeded, which will promote quicker recovery and will thicken your lawn. You can read more about Seeding your lawn here.

Scarification if done incorrectly can ruin your lawn. We have seen lawns butchered by incorrect Scarification and it can take up to a year for lawns to fully recover with a lot of time and effort not forgetting cost to put it right again. We would recommend Scarification is left to a great lawn care professional.

When Can I Mow My Lawn After Seeding?

Over time lawns can become thin and patchy, this is down to a number of reasons whether it is excessive wear and tear or a result of insect or fungal attack. Lawns can often need thickening up to improve their appearance and will benefit from seeding or over-seeding. When this process has been carried out it is time to think about how to maintain it and when to start mowing to help develop it into the lush green and healthy lawn that you dream of.

As a professional lawn care company we carry out a variety of services when we seed our customer’s lawns. We may start a lawn from scratch with bare soil, or carry out a renovation which will include aeration and seeding. We love lawn care and we know that the correct over-seeding on a lawn is critical to how it grows and develops into a lush green and healthy lawn.

A common question that lawn owners ask us either before they have their lawns seeded or afterwards is “Can I mow my lawn after seeding and when?” After all they don’t want to damage their lawn after investing time and money into getting it into great shape.

Newly seeded lawnWe want to give you great advice when it comes to lawn care and we would recommend following these guidelines after your lawn has been seeded.


  •  Leave your newly seeded lawn for at least two weeks, and longer if possible, before you attempt to mow it. This will allow the new seed time to develop roots

  •  Mow newly seeded areas at approximately 3” high from the first 4-6 weeks after the seeds have germinated – This means mowing a little higher than usual. If grass blades  are a little taller it will help retain moisture as they will shade the soil better.

  •  If you have a large area to mow, where possible try to use a walk-behind lawn mower for the first month after new grass germinates – It may take a little more time and effort,  but if you do this for a couple of mowings it will really benefit and help your new lawn establish itself

  • Be extra careful when turning your mower – Turning your mower too vigorously can tear out new plants. Where possible try to take longer rounder turns. This is most  important when using a ride on mower.

  •  Don’t mow when the ground is soft and muddy – When the ground is too soft and muddy it can cause ruts and your footprints may well sink in which will ruin your seeded  lawn. New grass plants are fragile and easily damaged. Be careful as they will get buried into the ground in these conditions.

  •  Mulching is preferable to collecting grass clippings – The compost you will create with mulched grass clippings will help to retain much needed moisture for new grass plants  and also provide them with more nutrients.
