Scarification is the name given to the mechanical means of removing surface thatch that has built up over the year, thereby enabling air flow, nutrients and moisture to reach the root zone. This results in healthier grass which is less prone to fungal attack.
Thatch is the matted layer, made up of living and dead organic matter, found between the grass plant leaf and the soil surface. Thatch (over 15mm or ½”) creates ideal conditions for moss and disease to thrive and, by reducing water, air and nutrients getting to the roots, it also prevents the grass plant from flourishing.
GreenThumb examines the depth of surface thatch on your lawn as well as its overall sponginess. If there is excessive surface thatch then we recommend scarification. Scarification should be a regular practice on any lawn.
Due to the rigorous operation of scarification, GreenThumb carries out this work during the out-of-season period so we can keep your lawn looking the best during the growing season.
Lawn raking, carried out using a leaf rake or raking machine with small wires, is a moss removal process. Scarification uses knives and blades to remove thatch and is a significantly more rigorous and thorough operation. Simply put, scarification is moss cause removal, lawn raking does not address the cause of moss.
Scarification waste is not removed as a norm, instead it is neatly bagged up for your disposal. We can put it on your compost or in your recycle bin. Alternatively, some branches provide, at a charge, the service of removing the waste for you; please check with your local branch.
