What is Scarification?

Scarification is the process of removing thatch and organic debris from the lower level of your lawn, if there is moss present then some will also be removed by the process, more may rise to the surface for a few days afterwards.  Removing the thatch build up helps to reduce the amount of moss that builds up in a lawn and keep the debris level under control which can help prevent issues such waterlogging and lawn diseases before they happen.

Which Machines?

Not all machines are created equal.  While a domestic lawn raker might seem similar to a scarifier it is not the correct tool for the job and may cause more damage to your lawn.  Top Lawn use the latest pedestrian machines that have bladed drums which rotate at high speeds to remove the thatch and debris from the lawn.

When should Scarifying take place?

Scarification is ideally performed in the spring or autumn and at least once a year.  During spring and autumn the grass is actively growing and will recover at a good rate.  After the lawn has been scarified it should be kept moist, and treatments including fertiliser can be applied, as appropriate.

When to Avoid?

Avoid scarifying in the winter months as the grass growth will have slowed to a near stop, and the lawn may be muddy, making its recovery time much longer.   Drought conditions can also cause your lawn to become distressed so should also be avoided.
