Advice on mulching

Many lawn mowers have a mulching kit or mulching plug. Here, we'll explain what mulching is, what the advantages are, and how to use the mulching function.

Mulching

Mulch is a layer of organic material to cover the ground on your lawn. The lawn mower produces mulch using the mulching function. The mulching plug blocks the collecting tunnel, so shreds of grass will keep flying around the mower deck. A special mower blade ensures the cut grass is shredded. These tiny shreds are blown back onto the lawn. Because they're so small, they'll fall between the blades of grass. This process is called mulching.

Benefits of mulching

The shredded grass creates a layer of mulch on the soil of your lawn. This layer of mulch protects the roots of the grass against heat and improves humidity. It also means weeds have less space to grow. The shredded grass decays quickly and provides nutrients for the soil and roots of the grass. This improves the health of your lawn and makes it less susceptible to weeds and thatching. Mulching is a way to mow your lawn and fertilize it in a single effort.

Mulch regularly

You maintain your lawn via mulching, which means you should nourish the grass regularly. That's why you should mulch at least 1 time a week during the off-season, and 2 times per week during the high season (May to September). You can also do this during fall, because you can also shred leaves. Don't use the mulching function with wet, tall, and overgrown grass. Wet grass sticks to the blade, so it won't be shredded properly.

Sowing grass

You need grass to be able to mow and mulch. Sometimes, you can have bare spots in your lawn. You can sow grass seeds and regularly fertilize to get your grass back into great condition. Calcium can also help your lawn. Use this when the soil is too acidic. You can also reduce the acidity of the soil with more sunlight, or with a drainage if the soil is too moist.
