Scarifying your lawn is an important job and will promote healthy growth, but what is it and how do you do it?
What is Scarification?
Scarification is a way of removing organic matter from lawns including moss and thatch. Thatch is a layer of dead grass and moss. Thatch can build up over time, when the layer is thicker than 1cm it can prevent water and nutrients from fertilisers from accessing the roots of the lawn. By scarifying, it improves airflow and creates space for more healthy lawn growth.
If your lawn suffers with moss problems or feels spongy underfoot this can indicate there is too much thatch and scarification is required.
How to scarify your lawn?
Before scarifying its good practice to mow the lawn. The Kent & Stowe Scarifying Rake is an ideal tool to use when scarifying, using a pull motion to scrape the thatch or moss. Alternatively, a spring tined rake can be used, using a brisk action. For very large areas a powered scarifier can be hired or purchased for the job.
Scarification can produce a large pile of dead thatch and moss. This can be added to your compost heap or disposed of in green waste bins.
Then after scarifying applying lawn seed will help produce a healthy, thick, and revived lawn.
When to scarify?
Scarifying the lawn early season in spring can help create space for the grass to thicken up. It is better to treat moss before scarifying as living moss can spread spores when disturbed.
It can also be good to scarify lawns in autumn. Scarifying will help reduce competition and gives the grass more room to grow. It also helps to minimise moss growth over winter, making it less of a problem in spring.
