The expert recommended a process called scarification

As sunny skies grace the UK, many people will head into their gardens ready to give their lawns a good freshen-up.

A gardener has shared a mowing technique that can leave grass looking "nicer, denser and greener-looking".


An expert known as Novice Gardener on YouTube explained why individuals should scarify their lawns - a method that involves using a tool to remove thatch, moss and other debris that builds up on the top of the grass.

He said: "We do this process for a few reasons. The first is to remove any excess thatch you might have within the grass.

Thatch is made up of "lots of dead matter from the plants" that were previously growing in your garden.

The gardener explained: "If you have really good grass, for the most part, they will break down the thatch and use it as lawn feed for the grass plants.

"However, we're not all blessed with having excellent grass. If you have a new build like myself, you will not be blessed with great grass, so we have to get on with scarifying and rake out any excess thatch."

Scarifying will "thin out the grass ever so slightly", leaving space for plants to thicken on your lawn.

The technique also removes any moss on your lawn, but the gardener advised using liquid iron afterwards to "slow the production" of moss in the future.

The content creator added: "The final reason we scarify is to prune the plant. Scarification, in its simplest terms, is a pruning technique. You are vertically cutting your lawn.

"It does thin out the grass to some extent, but if you have the right grass, it will encourage more lateral growth."

The expert emphasised that scarification is "quite an aggressive process and puts the lawn under quite a bit of stress", but it does set the lawn up nicely for feeding.

He said: "Once you've scarified your lawn, get on straight away with a lawn feed. The goal is to have the grass thicken up as quickly as possible.

"By giving the grass a feed, we speed up the regeneration process of the grass leaf to fill in the empty spaces."

Another gardener has shared a plant species he recommends Britons grow in their gardens.
