The importance of mowing

Regular mowing promotes a healthy lawn that is resistant to heat, drought and weeds, as well as less susceptible to disease.

The right height of cut

Did you know that the mowing height varies according to the season? When it is hot, it is better to keep a grass length of at least eight centimeters so that the soil remains cool and moist, which also requires less watering. Not to mention that the roots will not dry out under the influence of extreme temperatures.

During the spring and fall, we prefer a mowing of about five centimeters. When the fine weather arrives, this cleaning will have the effect of stimulating the growth of the grasses, while at the end of the season, this length will prevent the development of diseases in particular.

In any case, the grass should never be cut more than a third of its length. Better to mow the lawn shorter, but more often! Not to mention that a lawn cut too close will show all its little faults. If we can engage in the exercise on a weekly basis during the mid-seasons, we can however space it out every 10 days during the summer period.

When to mow

It is not recommended to mow when the grass is wet to avoid an uneven cut. Wet soil can become compacted. The end of the afternoon or the beginning of the evening are therefore good times to take out the mower. Provided, of course, that the rain has not played spoilsport in the previous days or that the air is not too humid. And as you now know that the longer blades protect the roots from drying out and help maintain an optimal level of humidity in the soil, it is better to avoid mistreating the lawn during heat waves and droughts.

Beware of noise

Noise regulations differ from municipality to municipality. Do not hesitate to inquire about the law in force in yours to avoid any problem with the authorities and the neighborhood.


An ecological and economical technique, grasscycling consists of leaving grass clippings on the lawn, which will then provide it with nutrients by decomposing, while preventing weeds from developing. Be careful, however, to distribute this cut grass well on the ground, no more than half a centimeter, to prevent it from suffocating the lawn.

Sharpen mower blades

Do you sharpen your lawnmower blades each season? A clean cut promotes turf regeneration and reduces the risk of disease.

Optimal watering

When it is not watered enough, the lawn stops growing and goes dormant. It will then turn yellow or brown during periods of drought, until it is irrigated again, for example during a rainy season. If the grass generally regains a beautiful appearance, well-maintained grounds will still be less vulnerable to diseases and pests.

How often to water

To avoid the proliferation of superficial roots, it is better to water your lawn deeply, but not too often, little, but more frequently. Be careful, since too much water can also affect the growth and good health of the lawn.

It is recommended to start watering it at the beginning of summer, around the end of June, once a week in the absence of rain, sometimes more during a heat wave.

If the amount of water varies according to the type of soil, a sandy ground will dry out for example more quickly than a clay soil, it is estimated that an irrigation of two and a half centimeters is generally optimal. To ensure this, you can place a few small containers in various places. Close the valve as soon as the containers are full, which should take an hour or two. Note, however, that grass near trees may require more water, as the roots of the latter are more greedy.

When to water

The best time to water your lawn is undoubtedly in the morning to reduce water evaporation due to heat and wind. If it is impossible to irrigate your land at the start of the day, you can do it in the early evening, provided that the lawn has time to dry before nightfall to prevent the risk of diseases caused by fungi.

As with noise, find out about your municipality’s regulations regarding watering.

Aerate the ground

By dint of mowing, watering and passing, the lawn becomes compacted and the roots end up running out of air. Over time, grass growth slows down and the blades dry out.

To remedy the situation, it is strongly recommended to aerate the soil every year, preferably in the spring. Uncompacted, your lawn will then absorb water and nutrients more easily, in addition to taking root more deeply.

Do not hesitate to ask your garden center for advice on which technique to use depending on your type of soil.

The benefits of fertilization

Like vegetable gardens, trees, shrubs and other plants, lawns also need nutrients to grow and develop in health. A fertilized lawn will also be less vulnerable to insects and diseases.

Grasscycling and topdressing with compost are particularly attractive options for meeting part of the lawn’s nitrogen needs. Regular watering will then allow the nutrients to penetrate the soil well.

The use of fertilizers adapted to the season also helps strengthen your lawn so that it remains healthy, all year round! Don’t forget to regularly inspect your lawn in order to quickly detect any problems.
