How do you take care of Ariocarpus trigonus?

Light Requirement 

In terms of the right light levels, Ariocarpus trigonus would prefer to have full sunlight and partial shade parallel. 

In other words, they would prefer to have full sunlight during early morning hours and partial shade during the hottest part of the day. 

The exposure to extensive sunlight may cause sunburns for them. Hence, do not leave them uncovered for full sunlight during the intensely hot warmer hours of the day.

Besides, if you have cultivated them indoors for too long and want to bring them outdoors I suggest you slowly expose the plants for full sunlight.

The abrupt exposure for sunlight would be hateful for the plants. When you grow them indoors you need to go ahead with a bright sunny windowsill. 

Moreover, if you still find it difficult to fulfill the sunlight requirement of the plants, you may supplement the lighting by placing grow lights closer to the plants. 

Temperature and humidity

Ariocarpus trigonus would want warmer temperatures to grow to their best potential. Further it would be quite crucial to produce flower blossoms as well. 

Ariocarpus trigonus plants are somewhat frost hardy up to -10 degrees Celsius given that you are keeping the plants dry. 

However never expose them for much colder conditions for too long as it would not be healthy on the plants. 

Consider that you have grown them outdoors and expect a severe frost condition, so I recommend the best thing you could do is to bring them indoors.

The optimal temperature which would perfectly fit in for these plants would be 5 degrees Celsius ( 41 degrees Fahrenheit ) in winter. 

On the other hand, a temperature range between 15-20 degrees Celsius ( 59-68 degrees Fahrenheit ) would be ideal for them during the rest of the year. They are tolerant of higher temperatures such as 40 degrees Celsius ( 104 degrees Fahrenheit 0

Ariocarpus trigonus usually grows in less fertile soil mixes which always tend to be dry. So, in cultivation also, you need to mimic the same conditions by providing a porous soil mix which is fast draining. 

The right pH Level of the soil mix should be between 6 and 7. That said that they can also survive in soil mix which have a pH range of 4-8 also. 

The most crucial factors to check on the chosen soil mix is whether they have excellent drainage and a good aeration.

Pot size Potting and Repotting

A terracotta or a clay pot would be ideal for these plants. Those are all porous materials which would ensure that the excess water would evaporate faster in the pots without retaining within. 

Additionally, your selected pot needs to have one or two draining holes also. When it comes to repotting the plants, I suggest you do it every other year so that it would provide new growing conditions for the plants.

Where to Plant 

You need to select a place where the plants can gain sufficient sunlight levels. It is the most crucial factor when selecting the right place to plant them.

Fertilizer and time of year
