Rid your lawn of thatch

Your lawn needs some TLC in the form of a scarifier. Aerating your lawn prevents moss and encourages grass growth, but only if you do it correctly.
It looks like you all feel the same, judging by the trending categories. «Scarifying» has been high on the list for days. So that you'll be able to find your way more easily in future, I've compiled an overview of the topic.
How does scarifying work?
Lawn thatch consists of grass cuttings and dead plant matter. This layer lies between the grass and the ground and inhibits the exchange of light, water and nutrients, resulting in fungus, moss and reduced root growth. Your lawn becomes unhealthy. To prevent this, it's best to remove this layer of thatch via scarification once a year.
Which is the right scarifier for me?
Whichever scarifier you buy, the principle remains the same: fixed or rotating blades sit around a horizontal axis and you or a motor rotate it to cut into the turf and pull out the thatch. Your choice of petrol, electric or manual scarifier depends on your lawn.
Petrol models, on the other hand, are best for maintaining large lawns. There's no troublesome cable, giving you the freedom needed for your sweeping plot. Its weight presses the blades deep down into hard, dry ground. This makes them more expensive and maintenance-heavy than their electric counterparts.
When should I scarify my lawn?
It's easy to tell whether your lawn needs to be scarified. Pick up a rake and loosely run it through the turf. If there are grass cuttings and moss hanging from the spikes, it's time for some lawn maintenance. Strong weed growth is another indicator.
How do I do it properly?
The preparation stage begins around two to three weeks before the job itself. Fertilise the lawn so that it has enough nutrients for optimal regeneration. Judge by the daffodils at this stage. If they're in full bloom, it's time for spring fertilisation. Before scarifying, cut the lawn to two centimetres. This should be the lowest setting on your lawn mower. Now you're ready to start:
• Adjust your scarifier to the correct height. The blades should cut around three millimetres into the turf.
• Move the tool quickly and steadily over the desired surface.
• Scarify your lawn lengthways and then crossways.
• Rake up the thatch, preferably adding it to the compost.
• Resow any brown patches and gaps and water the lawn (unless rain is forecast).
Your work is done, at least as far as scarification is concerned. There are obviously still some strenuous hours in the garden to come. But all in good time.
My life in a nutshell? On a quest to broaden my horizon. I love discovering and learning new skills and I see a chance to experience something new in everything – be it travelling, reading, cooking, movies or DIY.
