How do you take care of crassula marnieriana?

Light Requirement 

Crassula marnieriana appreciate full sunlight when they grow, especially when you grow them outdoors. 

Having said that, they can tolerate partial shade as well. Due to the demand of the sunlight they have , I recommend placing them at the brightest sunny spot at your home when you add them as houseplants.

Only then it will allow them to grow to their best and come up in the vibrant colors as aforesaid.

Temperature and humidity.

Crassula marnieriana are tolerant of cold and weak frost. In fact, they can tolerate a minimum temperature up to -2 degrees Celsius. 

However, you need to protect them from extreme frost unless it would create unhealthy repercussions on the plants. 

However, do not locate them near cold drafts and heat drafts as it would be unhealthy for the plants.


Crassula marnieriana produces flowers in pink or in white. Further their flowering season would be either in spring or in summer.

Is it cold hardy?

Crassula marnieriana are a little cold hardy as explained above.

USDA Hardiness Zone

Crassula marnieriana prefer to grow in USDA hardiness Zone 11a (Minimum 40° F | 4.5° C)

Watering Requirement

Watering the Crassula marnieriana plants accurately is the prime thing you want to do when looking after them well. 

If there are any lapses in watering them, it would create so many bad impacts on the plants growth and could even result in the health deterioration in the plants. 

If you had supplied water in abundance and grown them in a poor draining substrate that would be the biggest mistake that you would make when looking after them. it would literally kill the plants.

When watering, you need to water them in small amounts during the period of October to May. However, it could vary depending on the geographical area, weather and on the rainfall the plants get. 

Make it a habit to check soil moisture level before you water them. Ideally it needs to be dry. 

When you grow them outdoors, you should water them more often in summer and in spring. During these periods, the moisture in the soil evaporates faster.

However, except in this situation, ensure that you keep the potting medium dry between two watering sessions. 

You need to watch out for the moisture in the soil during seasons like in winter and in autumn as it will take a little longer .The reason for that is because the water evaporation would be slow during these periods.  

Once you complete watering the Crassula marnieriana plants, ensure that the excess moisture is draining away from the potholes.  

When you place the plants indoors during winter, it will anyway take a longer period to wither. Hence do not pour them with water in excess as it could create lethal impacts on the plants as explained in the above.

Soil Requirement Type / ph.

Crassula marnieriana requires a substrate which is not nourished with nutrients. They would ideally prefer to have a porous substrate which is well aerating and well-draining. 

If you grow them outdoors, you do not have to select any specific soil type given that the soil mixes available there are porous, well-draining and low in nutrients. 

You need to specially go for a potting medium which is well draining when you grow them as houseplants.

The reason for that is because they take a longer time to wither since they get low light levels.  

If you keep them in waterlogged conditions, it will lead the plants to rot. Hence, I urge you to use a cactus specific substrate as the best soil type to use when you grow them indoors. 

Additionally, you can use a universal culture substrate also for this purpose. However, when using them, ensure that you mix it with perlite also so that it will enhance the draining of the potting medium.

Pot size Potting and Repotting

Crassula marnieriana would perform well if you provide a pot which has a draining hole. Additionally, it needs to be a porous pot as well. 

When it comes to repotting the Crassula marnieriana plants, I recommend doing it in spring . 

Further since they are fast growers , you need to do it once every two years as explained in the beginning of the article.

Besides, when you repot, you need to go for a slightly larger pot. However, if you have planted them outdoors, you do not need to worry about transplanting them. 

However, if there is not enough space for them to grow, you can replant them somewhere where they can grow freely and vigorously. 

You have to follow the same steps which you would regularly do with the rest of other succulents when repotting these plants also. 

Where to Plant

Crassula marnieriana plants do not handle cold well. 

Hence if you live in areas where the temperature gets colder than the 40 degrees Fahrenheit, you need to plant them in pots which you can relocate easily in and out from the house. Keep in mind to fulfill their sunlight requirement when you shift them indoors.

Fertilizer and time of year

Crassula marnieriana do not have a strong demand for fertilizers. However, for the plants which you grow in pots, you can consider feeding

That would be quite productive particularly to enhance the flowering of the Crassula marnieriana plants. I recommend using fertilizers which are specially designed for cacti and for succulents from March to September. 

Further keep in mind that you should always feed the plants when their soil is moist. Besides, when applying fertilizers, you need to follow the instructions which are on the label.

How to propagate crassula marnieriana 

By cuttings

If you are wondering about the best way of propagating the Crassula marnieriana plants, cutting propagation method would be ideal.

First, wait until spring or summer comes and then start propagating them.

First, you must select the cuttings you wish to propagate. Next you can make the cuttings of the plants. When you make the cuttings, ensure that the tools you are using are all disinfected. 

Further ensure there are no remaining parts of the leaves also on the stems. Next leave the cuttings in a damp napkin for about one day. After that you can place the cuttings in the substrate and moisten them.

You will see how they produce roots within 10 days. Do not over water them as it would be the biggest mistake you would do when looking after the plants. Next place the specimen in a semi shaded place and let them grow.

By seeds

First, spring and summer are the best seasons to conduct the propagation by seeds. You need to select a location where there are sufficient sunlight levels for this process though

Furthermore, select a sandy well aerating and well-draining soil mix as well. Keep the soil slightly moistened. 

Ideal temperature here should be 23-27 degrees Celsius. ( 73- 80 degrees Fahrenheit ).

You need to first obtain the seeds from the plants and store them in a dry and dark place at room temperature. 

Next plant the seeds in the light soil mix whilst keeping a space of 2* 2 cm ( 1 inch – 1 inch ). The depth of the sowing should be 0.5 cm. It would take about 3-6 weeks’ time to produce the roots. 

In water

First obtain the leaves from the plants. Ensure the leaves you are selecting are healthy. . Further you can gently remove those from the stem whilst using your fingers

Further obtain the whole leaf for this purpose as only then you can have successful results of the propagation. 

Do not use damaged leaves for this as then you cannot guarantee the results. Next let those cuttings wither for about two days. That will allow them to develop callousness.

Finally, you can place them in water. To do that first arrange a cup where you can fit in the cuttings. After that add water into the cup and place the leaves slightly above the water surface. 

However, there are some people who let the leaves’ edges be in contact with the water surface also. That method will also work well. 

Next leave the specimen in a bright sunny spot but not in a place where they will be exposed for direct sunlight.

When they start rooting, you can water them as appropriate. Next you can plant those cuttings in individual pots. 

However, before planting , let them dry for a few days and only after that you need to plant them in a suitable potting mix. You can continue with the regular care treatments after that.


Crassula marnieriana plants are worthwhile plants which anybody would want to have. They would catch anybody’s attention due to the unique looks they have.

They would be excellent houseplants as well. All you need to do is to look after them well so that they will perform well. Happy cultivating with Crassula marnieriana !
