Which Water to Use for Watering Your Plants?

1. Tap Water: Friend or Foe?

Let's be clear: tap water won't kill your plants overnight. It's healthy and controlled. But it has two major drawbacks for plants:

• Chlorine:Added to kill bacteria, it can damage fragile roots.
• The Limescale (Hardness):Some plants (Orchids, Citrus, Carnivores) hate limestone, which alters the soil's pH.

The 24-Hour Tip (The Secret)

There is a simple and free solution: Let the water rest.

Fill your watering can right after watering, and let it sit in the open air until the next watering. In 24 hours, most of the chlorine naturally evaporates!

This is where design matters: choose a beautiful watering can that you will be proud to let sit in your living room during this resting time.

⚠️ Caution Water Softener:NEVER use softened water (by a salt system). Sodium is toxic to plants.

2. Rainwater: The Caviar of Plants

This is the water nature intended. It is soft, slightly acidic (which plants love), and at room temperature.

This is the ideal water, especially for sensitive plants like Calatheas (which brown with tap water) and Orchids.

How to retrieve it?

• For indoor use :Install a collector on your gutter. It's an investment that quickly pays for itself.
• In an apartment:It's harder. Put a bucket on the balcony during big thunderstorms. Otherwise, use filtered water (carafe) for your most fragile plants.

3. Temperature: Avoid Thermal Shock

It's often forgotten, but it's a common cause of mortality in winter.

If you draw ice-cold water from the tap (10°C) and pour it on a tropical plant accustomed to 20°C, you cause athermal shockat the roots. The plant stresses and can lose its leaves.

The Rule: Always use water at ambient temperature. Hence the advantage, once again, of leaving your watering can permanently filled in the room!

The Summary

No need to complicate things. For 90% of plants: Tap water left to rest for 24 hours at room temperature is perfect.

For Divas (Orchids, Calatheas): Rainwater or filtered water.
