Scarification! What is it and why do I need to scarify my lawn?
Overtime your lawn will suffer from a build up of organic matter which will eventually form a "Thatch Layer" which lays on the surface of your lawn. Thatch mostly comes from grass clippings and any other dead or decaying mater. If this is allowed to build up it will become excessive and have a damaging effect on your lawn, as it will weaken the grass and encourage the growth of both weeds and moss.
The only way to remove this is by scarifying your lawn, this is a physical process of removing thatch from the soil surface. To do this by hand (by raking) is a strenuous and physically demanding task. At Lawn and Weed Care Wirral we have specialist machines that can carry out this task in a far more comprehensive and efficient way than raking. As well as removing thatch and dead moss our scarifying machines will also prune the shoots of the grass plant to encourage stronger growth.
Scarification of your lawn is quite a vigorous process and after the thatch and moss has been removed your lawn for the short term may look far worse than before the scarification before your lawn recovers.
It is therefore important that the scarification of your lawn is only carried out at the appropriate time to enable your lawn to fully recover. Deep lawn scarification is best carried out early autumn whilst there is still enough growth for your lawn to recover. It is normally done as part of the Autumn treatment program and is almost always done before Overseeding and Top Dressing takes place. You would not want to go into the winter months with a thin sward that has not had sufficient time to recover. This would be an open invitation for moss invasion or disease problems.
The other window of opportunity for Scarification is early spring when the temperature starts to rise.
It is essential to apply moss control to your lawn about 2 to 3 weeks before lawn scarification. By not applying moss control first you will be spreading the moss spores causing further moss contamination of your lawn.
