How do you take care of crinkle leaf succulents?

Light Requirement 

Crinkle leaf plants can withstand semi shade. However, they are fond of growing in full sunlight. Literally they will perform well if they can gain full sunlight for six hours in the morning

When the weather is too harsh and intense, grow them while exposing them to semi shade. 

Hence, I recommend you book them closer to a bright sunny window. If they still lack adequate sunlight, you can grow them closer to grow lights.

Temperature and humidity

Crinkle leaf plants prefer to grow in warmer temperatures just like the rest of the other succulents. 

This literally means they would thrive well in warmer and dry weather. They can perform well in room temperatures and in room humidity levels. 

A temperature level above 50 degrees Fahrenheit would suit them the best. However, they can tolerate temperatures up to 20 degrees Fahrenheit also.

The exposure to frost for extended periods would badly impact them. Chances are that it could even be fatal on the plants too. 

When you grow them indoors, ensure that you are not placing your plants closer to cold drafts as the drastic changes in the temperatures could be unhealthy for them.

Is it cold hardy?

Crinkle leaf plants are not cold hardy plants.

USDA Hardiness Zone

Crinkle leaf plants ‘ preferred USDA zones is Zone 9a (Minimum 20° F | -6.7° C)

Watering Requirement 

A minimum water level would be sufficient for the survival of the Crinkle leaf plants. If you end up over watering them, chances are that it could even be lethal on them. 

Excessive water will create rots in the plants. Hence, it is critical that you check whether their soil is dry and then water. That will ensure that there will be no over watering. 

Once every two weeks would be enough during spring to fall. You could cut back on watering during winter and ensure that you do it infrequently to keep them moist only.

That will keep their leaves plump. Keep in mind that under watering will have less repercussions than over watering. 

You can easily revive an under-watered plant rather than reviving an overwatered plant.

Soil Requirement Type / pH

Crinkle leaf plant growth would be benefitted from a well-draining soil mix. Hence, a loose sandy soil would be ideal for this purpose. 

Best would be to use a readily available succulent soil mix or cactus soil mix to grow them. If you use a regular potting medium , the density would be high. A pH of 6.1–7.8 would suit these plants the best.

Pot size Potting and Repotting

It is mandatory that you select a pot which has sufficient draining holes to grow the Crinkle leaf plants. An unglazed pot would be the most appropriate pot type to use for them. 

The reason to use those pot materials is that their water evaporation is faster compared to other materials. 

In terms of repotting the Crinkle leaf plants, you do not have to do it quite often. They prefer to stay cramped in the planters. 

When you spot the roots, and the leaves are coming out from the pot you could consider repotting them into a new pot. 

All you have to do is to remove the plant from the older pot and grow them in a new pot. However, prior to that ,make sure that you check whether there are any rotten parts in the plant. 

If you find any , you can remove them and treat it with fungicide. Next when you plant them, you should plant them in the same depth that they were planted before.

Fertilizer and time of year

Can be toxic to pets

Crinkle leaf plants are toxic plants for pets as well as for humans. Hence ensure that your pets or the kids cannot reach them.

Common bugs and illnesses

How to propagate crinkle leaf succulent

There are two main propagation methods of Crinkle leaf plants, they are leaf propagation method and the seeds propagation method. 

However, the commonly used method is the leaves propagation method rather than the seeds propagation method. 

You cannot guarantee the successful result of the seeds propagation method , and it is somewhat difficult to do too.

How to conduct the leaf propagation of the Crinkle leaf plants

To start off, twist a leaf from the stem. When you twist the leaf , ensure that you are obtaining the whole leaf as it will consequently assure the successful results of the propagation. 

Alternatively, you could collect a dropped healthy leaf also for this process. Next, allow the cuttings to develop calluses and then plant them in a well-draining soil mix.

How to propagate the Crinkle leaf plants by using the seeds

You only have to sow the seeds in a well-draining potting mix whilst exposing them to warmer temperature levels. 

However it will be time consuming though since it will take a longer period to show the results. 


Crinkle leaf plants are such great plants to have in your indoor garden collection or even in your outdoor garden collection. 

All you need to ensure is that you look after them well so that they can grow to their best. Happy cultivating with Crinkle leaf plants !
