Scarifying your lawn: a simple guide
Give your lawn a new lease of life: scarifying loosens the soil and helps you get that lush, green look. What do you need to look out for, what are the steps to follow, and which scarifier is right for you? Find all the top tips right here.
What is lawn scarifying?
Scarifying is like a deep-cleansing treatment for your lawn. Using a scarifier, you lightly score the turf to comb out mulch, thatch and weeds. This scoring action encourages the grass to produce new shoots, while combing out the debris helps the soil to breathe. This prevents mould and optimises the supply of nutrients. The result? A denser, healthier and more beautiful lawn!
When should you scarify your lawn?
The best time to scarify your lawn is in spring – before any other lawn care tasks. This optimally prepares the grass for the growing season. If necessary, you can scarify it again in autumn, but no more than that. Find out what else you should do throughout the year in our lawn care guide!
Which is the best scarifier?
Scarifiers are similar to lawnmowers, but they are tailored for their specific task and are available in different models. Which one is the best fit? You decide:
Petrol ScarifierPerfect for large areas, powerful and with a long reach.
Cordless ScarifierGreat for medium-sized areas, easy to handle, versatile and quiet.
Electric ScarifierExcellent for medium-sized areas and also very quiet
Hand ScarifierIdeal for small spaces, great value and quiet.
Good to know: Scarifiers with a collection bag gather the removed thatch straight away. You can also find lawnmowers with an integrated scarifier. These 2-in-1 devices save you space and money.
Scarifying your lawn: Four steps to perfect lawn care
- Mow the lawn
- Set the cutting depth
- Scarify methodically
- Lawn aftercare
1. Mow first, then scarify
Although scarifying is important for your lawn, it also puts it under stress. That's why you should leave it to rest for a while after scarifying. Before you scarify, you should mow it two to three times. Cut the blades of grass to a length of about 2 cm.
2. How to scarify correctly – how deep should you cut?
Scarifiers can be set to a specific cutting depth. You can determine this by placing the scarifier on the ground – the blades should just about touch it. A short test run will show if the cutting depth is set correctly. As a general rule:
- For a young lawn with a shorter root system, opt for a cutting depth of no more than 3 mm.
- Work on an older lawn with moss and weeds with a depth of up to 5 mm.
3. How should you scarify your lawn?
In a random criss-cross pattern? It's best not to. Scarify the area methodically – first in straight lines lengthways, then in straight lines crossways. This chequerboard pattern will ensure you cover every spot.
4. What should you do after scarifying?
After a deep clean comes deep care: if you lime, fertilise and water your lawn after scarifying, the nutrients will be absorbed by the soil much more effectively. If any bare patches appear after scarifying, reseed these areas with new lawn seed.
Frequently Asked Questions about Scarifying
Yes, as long as you mow the lawn before scarifying, you can do both tasks on the same day. After scarifying, you should take a break from mowing.
Scarifying and fertilising your lawn – what you need to know
Scarifying your lawn is unnecessary if it has very little thatch, looks perfectly healthy, or during periods of extreme heat or cold. You should also avoid scarifying young lawns.
Aerating is not the same as scarifying. When aerating, the soil is loosened deep down to make it easier for water to drain away. This is rarely necessary for a normal garden lawn – the aeration provided by scarifying is sufficient.
