On the other hand, there are some people who say that they can survive with indirect bright sunlight and not with the bright full sunlight.

However, what I recommend you do is to expose the plants to bright indirect sunlight at first and then slowly expose them to full sunlight slowly. 

I recommend you start it off by exposing them to morning full sunlight first as it is not that intense when compared to midday sunrise. 

In case if the plants come across any scorching in the plants, you can place them in a shady place. Ensure that you fulfill the sunlight requirement of these plants as it will enable the plants to become vibrant in the colors. 

If you fail to expose them to proper sunlight, they will tend to lose the usual blue gray green color and instead they will tend to take a greener look.

Temperature and humidity.

In terms of the humidity, low humidity levels would work well with them. If there are high humidity levels available, it will make the plants more prone towards root rot. 

A temperature range around 45 degrees Fahrenheit ( 7 degrees Celsius) would work well with these plants. 

Is it cold hardy?

Titanopsis calcarea plants are somewhat cold hardy.

USDA Hardiness Zone

Titanopsis calcarea plants are cold hardy in USDA Zone 10 ( 30 degrees Fahrenheit).

Watering Requirement

Titanopsis calcarea plants can thrive with minimum water. They prefer to stay dry and if you water them in excess it will create root rot. 

There will be less severe repercussions from under watering than over watering. Moreover, always ensure that you water the plants deeply.

If you are using tap water for them, you need to leave them in the watering can for at least one day so that all the chemicals will evaporate. 

Besides, do not splash water on the plant’s leaves. If you mistakenly do so, there will be water trapped in the rosette and it will lead to root rot. 

Further, the ideal time to water the plants would be in the morning so that it will allow the plants to dry out before they expose for cooler evening temperatures.  

If you come across a situation where the leaves get floppy or become translucent , it literally means the plants are overwatered and you need to cut back on watering.

Soil Requirement Type / ph.

Titanopsis calcarea plants perform well if you grow them in a potting medium which is well-draining. To fulfill that, you can make a perfect soil mix by mixing universal soil mix and coarse sand and perlite. 

Instead, you may add expanded clay as well. When you add these elements , the draining of the pot would be benefitted.

Moreover, you can grow them in a soil mix which is specifically made for succulents and cactus as they also have a fast drainage. You can easily acquire them from the garden stores.

Pot size Potting and Repotting.

It is vital that you provide a porous pot to grow the Titanopsis calcarea plants. Hence a terracotta pot or an unglazed clay pot would do. 

The purpose of growing them in porous material pots is that the excess moisture remaining in the pot will evaporate rapidly.

When it comes to repotting, you do not need to repot them on a frequent basis as these are slow growers. 

Hence, they can survive in the same pot for so many years. Furthermore, it would be better if you could repot the plants once you freshly purchase them from the stores.

You could do the transplanting during spring as it would be the best time to conduct the repotting.

Where to Plant 

Ensure the place you selected to plant them is a place where they can gain sufficient sunlight levels.

As mentioned above, it is important that you let them gain sufficient sunlight as only then they thrive well. 

Additionally, if you grow them as houseplants, ensure that you stick to aforesaid guidelines with regards to the potting mix and the pot.

To propagate you need to first wet the seed compound and then sow. After that you can place the specimen in a bright, shady moist place. 

Those conditions would be optimal for the germination process. Ideally you need to keep the seeds in the seedbed until they produce at least a couple of leaves. Next you may place them in individual pots.

Besides the seed’s propagation method, you can consider using the division method to propagate them. 

When you spot the new clusters have grown significantly , you can propagate them. Ideally only then they can produce roots on their own.
