When to Water a Cactus?
of reading
It is often said that the cactus is the immortal plant, the one that cannot be killed. This is false!
Paradoxically, most indoor cacti die... from drowning. Accustomed to arid environments, they store water in their tissues (succulents) to survive.
But "drought-resistant" doesn't mean "water-free." Here's how to find the perfect balance to get your thorny plants to bloom.
1. Understanding the cycle: Summer vs. Winter
The secret lies in the calendar. Your cactus doesn't live the same way all year round.
Spring/Summer (Growth)
It's the active season. It's thirsty! Water it as soon as the soil is dry (about once a week if it's hot). Water thoroughly: the water should soak through the pot.
Autumn / Winter (Rest)
As soon as the days shorten, the cactus goes dormant. Its metabolism stops. You must drastically reduce watering (once a month maximum, or even stop completely if the room is cool). If you water it too much in winter, it will rot.
2. How to water without causing rot?
The cactus's body (the stem or pads) hates stagnant moisture. Pouring water on it can cause brown spots or rot.
The Golden Rule: Aim for the soil, not the plant. The water must go directly to the roots.
For this, you need precision tools.
The collectors' secret tool
For small cacti and succulents crowded in their pots, a watering can is sometimes too big. The solution? A watering pipette.
It allows water to be deposited drop by drop, exactly where it is needed, without wetting the body of the plant.

3. Should you mist a cactus?
Unlike tropical plants, cacti do not need ambient humidity. However, they have one enemy: dust .
Dust accumulates between the spines and prevents the plant from absorbing light. Once or twice a year, use a spray bottle to "wash" your cactus and restore its shine. Do this in the morning so it dries quickly.

The brass sprayer is ideal for gently dusting your cacti without drowning the soil.

Your cactus is talking to you, learn to listen to it:
- It's becoming soft, yellow or black at the base: That's rot! You've overwatered it. Stop watering it, put it in the sun, and pray. If the base is black, it's often doomed.
- It's shriveling or shriveling: It's thirsty! It's drawing on its last reserves. A good watering (soaking) should revive it within 24 hours.
- It leans towards the window: It's looking for the light. Turn the pot regularly.
In summary
The cactus likes extremes: lots of water all at once, then nothing for a long time. Be generous, but infrequent.
