How do you care for a cactus? Is it really an easy plant?
The cactus is known as the ultimate easy houseplant. A plant that requires almost no water, lasts for years, and is even suitable for those without a green thumb. But... is that really true? Yes and no. A cactus is indeed easy to care for, but only if you know what it needs. Because while it doesn't require much, there are a few important rules you absolutely must follow.
Why many people care for a cactus incorrectly
The biggest mistake? Overwatering. Despite a cactus's appearance as a true survivor, it can rot in no time if the soil remains constantly wet. A cactus stores water in its stem, allowing it to go for long periods without water. If you water too often, you're essentially suffocating the roots.
In addition, cacti often don't get enough light at home. Cacti are sun worshippers: in the wild, they grow in dry and warm areas where the sun shines for many hours a day.
Can a cactus tolerate cold and darkness?
The short answer: no .
But... in the desert, it can get freezing at night. Cacti can survive this even there, but only for a short time. So, a cactus can handle a cold night for a while. Just put it back in a bright, warm spot afterward.
How to care for a cactus in a terrarium – Simple step-by-step plan
1. Watering: less is more
-
Spring and summer: Give a splash of water about once every 3–4 weeks.
-
Autumn and winter: even less, sometimes even once every 6–8 weeks.
-
In doubt? Check the soil:
-
Dry/light gray: then you can add water.
-
Damp/dark gray: wait a little longer.
-
Can't reach the earth? Look at the color of the soil.
-
2. Light: the cactus likes a lot of light
-
Place the cactus in a light spot.
-
A south or west facing window is ideal.
-
Avoid places with little daylight — it will slowly wither away there.
-
In a terrarium, the cactus should not be placed in full sun: the glass will then act as a magnifying glass and can burn the plant.
3. Temperature
-
Cacti like warmth, but can also tolerate cooler periods.
-
In winter, many species even find a temperature between 10–15°C pleasant.
4. Nutrition
-
During the growing season (March to August): feed the cactus once a month .
(You don't have to — cacti can go years without feeding.) -
In winter: do not feed, because the plant is dormant.
Is a cactus really easy?
Yes.
But only if you go along with its natural rhythm.
A cactus isn't a plant you need to water every week or put in a dark corner. But give it:
-
sufficient light
-
little water
then it is one of the most forgiving plants you can have.
Even if you forget about him, he often survives without any problems.
