Scarifying the lawn is an essential task that should be carried out on a regular
basis to maintain good lawn health and vigour.
What is a lawn scarifier
Lawn scarifiers or lawn rakes are machines that remove thatch and moss from the
base of the lawn. Lawn scarifiers are generally walk behind machines, powered by
either electric or petrol.
A lawn scarifier or rake consists of a row or several rows of vertically mounted
tines or blades. These tines or blades rotate very quickly as they slash into
the base of the lawn and remove debris such as thatch and moss.
When to use a lawn scarifier
These scarifying machines are used during periods of strong grass
growth, as this enables the lawn to make a quick and speedy
recovery. Lawn scarifiers are commonly used during the spring period (following
moss control) and late summer / early autumn for intensive thatch removal.
However these machines can in fact be used at regular intervals during periods
of strong grass growth in the summer months too. This help prevent any lateral
grass growth, prevents thatch build up, creates a firm lawn surface and helps
discourage many broad leaved lawn and turf weeds.
What is thatch
It is important that the build up of thatch
is kept in check as when it becomes excessive the quality of the lawn will start to
deteriorate. It could be argued that an excessive layer of thatch is more
detrimental to the lawn than any other lawn care problem.
This is because too much thatch is the main cause or part why we get other lawn
care problems. Most other problems associated with poor lawns often originate from
too much thatch in the lawn.
Common problems caused by excessive thatch include disease, weeds, shallow
rooted grasses, poor drainage, poor drought tolerance, moss invasion.
Therefore by reducing the thatch layer to an acceptable level, the lawn will be
healthier, with a thick coverage of grass that will be the envy of your
