What is Scarification?

Scarification is a very important lawn operation and should only be completed with a professional machine. A scarifier is a powerful machine that removes the thatch layer, organic matter and debris between the lower leaf level of the lawn.

Scarification is not designed to remove all the moss from a lawn. However, scarifying will remove moss to a certain extent. But to use a machine solely with the intention of fully removing moss may cause unavoidable damage to your lawn.

The action of the scarifier will loosen moss, and during the process and for a few days afterwards, it will allow it to come to the surface.

The removal of thatch build-up is the main objective of scarification. The removal of this layer helps to reduce the build-up of moss in a lawn, therefore helping the lawn to recover to it’s peek condition. By avoiding scarification, it allows the thatch and debris level to increase, which lead to further problems. Thatch and moss-infested lawns are not very drought tolerant for example.

When SHOULD My Lawn Be Scarified?

The best time to scarify your lawn partly depends on the time of year. This will ensure that the process works as effectively as possible.

A light scarification can be beneficial during good growing conditions in the summer. However some lawns, particularly fine fescue grass lawns may need scarifying twice within a twelve month period, to allow the lawn to recover back to full heath.

Spring time onwards is the best time to have your lawn scarified as the lawn will recover much more quickly when it starts to grow. Autumn is also acceptable as the lawn will still grow at a quick enough rate to fully recover.

When SHOULDN’T My Lawn Be Scarified

You should not have your lawn scarified in the winter season as grass almost completely stops growing at this time of year, meaning it can take months to recover back to good health. Lawns can take longer to recover when the tempertaure suddenly plummets. Due to the slow recovery process in winter months, your lawn could also become very muddy. Any frost that is likely due will also have a significant impact on your lawns recovery.

Similarly, lawn scarification should not be completed in drought conditions either as grass can become very stressed during these periods.

When receiving a quotation, Lawn Master can help you to choose the best time to scarify your lawn. This would be based on the grass type, current weather conditions and the time of year.

It is best to combine scarification with other operations, such as over-seeding and top dressing. However, scarification is the first process that must be completed before considering these additional options.

Professional Machines

Lawn Master uses the latest pedestrian machines, which have bladed drums with tungsten tips that rotate at very high speed to pull out the thatch layer from the turf.

Many people believe that a lawn raker is capable of achieving the same results as a scarifier. However, scarification should not be confused with a lawn rake. Using a small DIY electric powered machine can cause more harm than good when used incorrectly.

Domestic lawn rakers are only suitbale for very specific purposes where professional machines are less suitable, as Matt Evans explains in the video below.

Scarifying a lawn with a professional scarifierAfter scarification, lawns need to be kept moist. Afterwards, a fertiliser application can be applied to speed up growth and recovery. Over-seeding and top dressing are optional proccesses that can be applied afterwards to help to form a base for holding nutrients for the future months.
