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?
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.
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.
