Watering Techniques

With global warming, precipitation is becoming less and less abundant. It is therefore important to quench your plants without wasting drinking water.

Watering frequency

Of course, everything depends on the climate, the type of soil and the specific needs of the plants. In addition, the inclination and orientation of a terrain influence the rate at which a soil dries out. A south-facing or steep slope requires more frequent watering than flat land exposed to the morning sun alone. On the other hand, some types of soil, particularly those that contain a large amount of clay, dry out more slowly than others.

In general, rely on the degree of dryness of the soil to determine the right moment. Before watering a bed, dig a 10 cm deep hole using a trowel. If the bottom is warm and dry to the touch, it is time to water; If the soil is moist and fresh, the soil contains enough water. In the case of a bed of newly planted annuals or plants, water when the soil is dry to a depth of about 5 cm. The lawn can be watered if the soil is dry at the roots, or at 7 or 8 cm.

Moment and technique of watering

Avoid watering in the middle of the day when it is hot, as up to 50% of water will evaporate before entering the soil. Whenever possible, drink your plants in the morning or, failing that, in the early evening. In this case, the foliage of the plants must be dry before night to reduce the risk of diseases caused by fungi.

Avoid watering only the first few centimeters of the ground. The water must penetrate deeply to promote the development of long roots allowing the plants to survive the next drought. For the soil to be well moist, it is preferable to water slowly, in the form of fine droplets, especially for clayey or heavily tilted soils which can not absorb much water at a time. In case of runoff, resume watering a little later.
