The heat wave is currently affecting France. We are all stuck in the same mental cycle. You stand in the shower, wash off the sweat and watch the clock tick. You feel guilty. You apologize to the water for wasting it. It feels like a moral victory.
But look outside.
The garden drinks carelessly.
A ten-minute shower uses about 100 liters of water. That’s a lot. But heavy lawn watering? This can be more than 500 liters in one go. The imbalance is absurd. It would almost be comical if the resource wasn’t so valuable. As restrictions mulchingiply in all departments, we need to stop staring at the bathroom faucet. Most of the summer waste does not come from the shower. It’s between the tomatoes and the grass.
The silent culprit: watering the garden vs. personal hygiene
Let’s look at the numbers to reset the clock. A ten-minute shower consumes about 100 liters of drinking water. Classic garden irrigation? 15-20 liters per square meter is consumed per one pass.
Multiply that volume by an average lawn or family vegetable patch and your meter goes wild. In mid-summer, watering accounts for up to 50% of household water consumption if you have an outdoor area. This number is massively underestimated. It drowns in the surrounding guilt about our domestic habits.
Herein lies a cruel paradox: we count every drop under the shower head. However, we left the automatic sprinkler system running in the heat. At this point, evaporation has already destroyed half the volume before it even reaches the roots.
The smart trio: mulching, ollas and rainwater
Good news. There are solutions. They do not require any assets.
First, mulching. This is the forgotten hero of French gardens. Wood chips, dried grass clippings, straw or dead leaves around plants limit evaporation. You reduce the need for water by half.
Next ollas. These are porous terracotta vessels buried near plants. They slowly release water directly to the roots. Not a single drop reaches the surface or the air.
Finally, the rainwater collector. This is often subsidized by local government and constitutes a reservation. It covers a large part of summer needs without affecting the drinking water network.
- Mulch : Saves up to 50% water.
- Ollas : Progressive distribution. No evaporation.
- Rainwater Collector : free, sustainable conservation area.
Three simple, complementary gestures. They radically change the garden’s water footprint. You don’t have to sacrifice tomatoes or hydrangeas for this.
Change your habits before the ban takes effect
Equipment is important. But habits are more important.
Water early morning or late evening. When the sun doesn’t pump half the volume back into the atmosphere, the difference is tremendous.
Drip irrigation, previously reserved for experienced gardeners, is becoming more affordable. You can install the kits yourself.
The selection of plants is huge. Lavender, rosemary, sedum and grass can tolerate heat without daily downpours. English lawn? Requires water streams to stay green.
Adopt these habits before prefectural regulations make them mandatory. In many regions, this deadline comes every summer.
So the next time you’re feeling guilty in the shower, take a detour through the garden. Audit your exterior. Invest in thick mulch or a terracotta jar. Install a collector at the end of the gutters. These gestures weigh heavier on the bill and on the resource.
What if tomorrow’s true luxury is a garden that grows without thirsting the planet?
