How do you take care of Ariocarpus kotschoubeyanus?

Light Requirement 

Ariocarpus kotschoubeyanus plants would flourish given that they can gain full sunlight ideally in the morning hours. 

However, when it is the hottest hours of the day, it would be ideal if you place them in a location where they can gain filtered bright sunlight. 

If you expose them to excessive sunlight, it will make the plants scorched. I recommend placing the plants in a shady spot during these times so that they will be protected from those adverse conditions.

Temperature and humidity

Warmer temperatures would be optimal for the Ariocarpus kotschoubeyanus plants to grow well. Having said that, they have a frost tolerance up to -10 degrees Celsius. for short periods also. 

However, I recommend bringing the plants indoors if you have grown them outdoors during winter. It is advisable to grow the plants exposed to warmer temperatures all round the year. 

In terms of the right humidity levels, best would be to grow them while exposing them for low humidity levels. s

Is it cold hardy?

Watering Requirement 

Ariocarpus kotschoubeyanus plants would require a moderate watering to perform well. These are adapted to grow in hot and arid conditions and due to that you need to avoid over watering as much as you can.

You should water the plants Depending on the weather conditions. Ideally you need to water them more often during hot and warmer conditions in summer. to be precise you may water the plants once every week in summer. 

On the other hand, you need to cut back on watering in winter. In fact , once a month watering would be adequate for them in winter.

You need to water the Ariocarpus kotschoubeyanus plants in a way where you don’t make their soil too soggy. 

Furthermore once you complete watering the plants, make sure that all excess water is draining out from the pots without retaining within. 

Soil Requirement Type / pH

I encourage you to use a mineral soil which consists of well-draining materials. I suggest you use a potting mix which consists of materials such as sand, pumice, and perlite. 

If you wish you can make an appropriate soil mix on your one to grow these plants. Furthermore, if you don’t have much time to spare on this, you can simply go ahead with the specially made succulents and cactus soil mixes which are available in the gardens stores, 

Never use a poor draining soil mix, as it makes the soil retain excess water. Consequently, it would result in the rot of the plants. 

If it is essential, you could disinfect the soil mix and then use so that you are sure that it will be completely safe for the plants.

Pot size Potting and Repotting

I suggest you go ahead with either terracotta pots or with clay pots as they are high in porosity. 

High porosity is very useful for these plants as they would ensure that there will be no excess moisture retained in the pots. 

Furthermore when it comes to repotting the plants, you could consider doing that less often. It would be better if you could repot the plants once you bring them home as chances are that they would have been grown in poor quality soil mixes. 

On another note, if you think they have gone through a pest attack, I recommend repotting them as it would provide new growing conditions for the plants. 

To do that you may simply remove the plant from the pots and snip off if you find any rotten and decaying plant parts. After that you could treat those cuttings with fungicides and grow them in a fresh pot which is filled with a fresh soil mix.

Fertilizer and time of year

I suggest you feed them with a light cactus fertilizer when they are actively growing. 


During autumn, these plants would emerge with bright pink to violet-colored flowers.
