Once a year it is important to free the lawn of thatch. This basic cleansing method, in which you also get rid of creeping weeds, is called scarifying. How will your lawn benefit from scarifying, and how does it work?...
Lawn thatch is more than just a blemish. The brownish woolly substance made up of plant matter and the remains of clippings makes life permanently difficult for your lawn. The dense thatch is a hindrance to the circulation of air, as well as to the free passage of water and fertiliser. Like a sponge, the thatch structure absorbs water and holds onto it. As such, despite adequate watering the roots are not sufficiently supplied. In the moist micro-climate of the thatch moss and lawn diseases, like, for
example, snowy fungus spread. Another undesirable consequence of lawn thatch is the gradual flattening of the grass roots. In dry periods it becomes more and more difficult for the grass to get to the moisture in deeper soil layers. To sum up: the thatch has to go, and WOLF Garten's scarifiers will help you in your quest for a thatch free lawn.
Only blades made from special steel are used in our scarifiers. They groom the lawn gently and effectively. You can set the working depth of the fixed blades from the handle with an infinitely variable adjustment. A scarifier's sharp, rotating blades systematically clear out the lawn thatch and creeping weeds from the lawn. WOLF Garten's scarifiers have received several performance related awards, and one reason for this is the patented scarifying system with the fixed precision blades made from special steel. They remove the thatch in a particulary effective and precise manner.
When and how is scarifying actually done?
Once a year you ought to free your lawn from thatch. The best time for this is a dry day in Spring (March/April), when the grass is just starting to grow. The exact setting of the working depth is important. The surface of the soil ought to be scraped, but not slit open, since scarifying too deeply will damage the grass roots. Please note that it is normal for a lawn to look a little worse for wear after this intensive cleansing.
Follow up scarifying by fertilising your lawn - after a few days the gaps will close up very quickly, and the lawn will become dense and green. Large bare patches can simply be re-sown with our high-quality grass seed.
