Just water what you need

Water is scarce and must be preserved. How to water then, especially with drought? Review of the reflexes of watering to adopt ...

Plants needing water to live, the garden can not do without watering. A better knowledge of the needs of the plants and the techniques to be implemented to reduce the consumption of water avoids wastage. With a well-landscaped garden, the savings will be all the more important.

1. Basic rule: know when to water

In summer, water only early in the morning, very late at night or at night, to limit evaporation due to the sun. In winter, do the opposite, watering the evergreen plants in the middle of the day to avoid frost damage at night.

No need to water when it is raining or when the soil is still very wet. If you use automatic watering, install a humidity sensor connected to your programmer, this is the surest way to avoid triggering the watering at the wrong time, after the rain for example.

2. Multiply the tips for saving water

Improved use of water in the garden positively influences the atmosphere around the house. Thus, during the summer season, the creation of pools, ditches and waterways that collect runoff re-humidifies the soil. When the water stagnates for a long time in the pools, oxygenate it with jets, artificial waterfalls and aquatic plants. This will give extra animation to your garden.

3. Respect the needs of plants and the nature of the soil

Plants with shallow roots, such as rhododendrons and camellias, should be watered often but with little water at a time. Those whose roots sink into the ground require rather a copious watering, once a week or every two weeks.

If the soil is porous or sandy, moisten the soil near the stump for the roots to drink water as it dries quickly. The micro-sprinkler (aerial watering that moistens the foliage of plants) is the best way to water without wasting while bringing the water to the right place.

If the soil has a clayey tendency, drip is the most economical solution, because the water infiltrates slowly, spreads on the surface and gradually moistens the layers of the soil.

4. Choose your plants

Choose sober plants that only need water once a week (they are now listed in the nursery catalogs).

Adopt spring flowers that will not need to be watered in summer, perennials that root for several years, rather than seasonally greedy water because faster growing.

Instead of cut plant walls that drain the soil and require water to rebuild their shoots, opt for free hedges, which are self-sufficient.

5. Care for your plants and soil

Soiling the soil is like breaking the surface crust that prevents rain and water from seeping through. An opportunity to check the famous saying: "A good hoeing is equal to two waterings"!

Covering the soil with mulch (buckwheat hulls, poplar mash, cocoa pods, flax straw, ground trash, etc.) keeps freshness longer, and prevents weeds from growing. .

Spreading a thick layer of compost in the fall on the soil of the beds and at the foot of the shrubs improves the texture of the soil, which will better retain the water afterwards.

More tips to consume less water

- Recover rainwater: this avoids depleting groundwater.

- Reduce the surface of your lawn: frugal ground cover plants keep beautiful foliage, even without watering. Some, like zoysia, frankenia, creeping thyme and azorella, keep between 5 and 10 cm high.

- The large lawns can be mowed differently, short and clean around the house and left in meadow further for mowing in late summer. Because the more the grass is mown often, the more it requires water to repel, while the meadows do not need to be watered.

- Prefer manual watering for the massifs near the house: the time spent at this work will make you thrifty!

- Plant preferably in autumn: trees, shrubs and perennials will benefit from the rains and will take root during the winter. They will be better prepared to fight against drought the following summer.
