Water your plants with demineralized water?

of reading

Do you have a jug of water for your iron and wonder if your plants would like it too? Or perhaps you're looking for a solution against that white deposit that stains the leaves of your Ficus?

Tap water is often too hard (calcareous) for some delicate plants. Demineralized water seems to be the miracle solution. It is pure, chlorine-free, and lime-free.

But beware: used pure and all the time, it can cause deficiencies. Let's discover together when to use it and for which plants.

1. Demineralized Water: The Queen of Misting

If there's one use where demineralized water is mandatory, it's theSprayer. Why?

For the plant:Tap water leaves white marks (limescale) on leaves when drying. These marks clog the plant's pores and are unsightly. Demineralized water leaves the foliage impeccable.
For the tool:Limescale is the enemy of your sprayer. It always ends up clogging the fine nozzle. Using demineralized water guarantees the longevity of your equipment.

Protect your investment

A beautiful mister deserves good water. By using demineralized water in our brass model, you maintain a perfect mist year after year.

✨ Zero Trace: Your plants stay shiny and clean.
⚙️ Preserved Mechanism:No more nozzles clogged by limescale.

2. Which plants need pure water?

Root watering with demineralized water is not necessary for all plants (it's expensive and useless for a geranium!). However, some specieshateminerals and limescale. For them, it's a matter of survival:

🥩 Carnivorous Plants (Venus Flytraps, Sundews)

That's rule #1. In nature, they grow in very poor soils. Water a carnivorous plant with tap water (rich in minerals), and you will burn its roots in a few weeks.For them: Demineralized water or rainwater is mandatory.

🌸 Acid-loving Plants (Azaleas, Orchids, Ferns)

These plants love acidic soils. Tap water (often calcareous/basic) will unbalance their soil and cause their leaves to yellow (chlorosis). Occasional watering with demineralized water helps to rinse the soil.

3. Beware of deficiencies!

If demineralized water is "clean," it is also "empty." It contains no calcium, magnesium, or iron.

If you water a classic plant (Ficus, Pothos, Monstera)onlywith demineralized water, it will eventually suffer from deficiencies and its growth will stop.

The Solution?Mix! Do 50/50 (half tap, half demineralized) or add liquid fertilizer regularly to compensate.

4. How to improve tap water for free?

If you don't have carnivorous plants, tap water is often sufficient. Its only drawback is theChlorine (added to make it drinkable), which kills the good microorganisms in the soil.

The Waterer's Tip:Chlorine is a volatile gas. Fill your watering can and let it sit for 24 hours in the open air before watering. The chlorine will evaporate on its own!

Patience has style

Letting tap water sit is good. Doing it in a design object is better. Stop leaving plastic bottles lying around: use our golden watering can as a carafe for your plants.
