Moon cactus do not require a lot of care, treatment and maintenance just like the other cactus and all succulents in general.

They will thrive well if we supply their basic growing requirements. Having said that, that does not mean that they could live longer.

As aforesaid, moon cactus live short due to their incompatibility with the two plants used for the grafting process.

Moreover, when rootstock outgrows from the pot, top part tend to die soon. That would be the most prominent reason .

Normally, grafted plants live longer. However, rootstock (base part) and scion (top part) combination make it incompatible for the moon cactus to live longer.

The growth rate of these two plants is also in contrast to each other and it makes the root stock of the cactus grow faster than scion. This is what causes the moon cactus to perish soon.

In addition to this, moon cactus would perform well when they are not exposed to an abundance of rainfall too.

Consider that if you live in an area where your cactus will be exposed to frequent rain, then the most ideal thing to do is to place them in a covered porch in case you have located  them outdoors.

You could identify whether your moon cactus require water simply by checking their soil and feeling it.

In case you think the dirt is dry and dusty, you need to water them mildly. Avoid watering them too much though.

You need to avoid over watering them unless that would make the potting soil waterlogged and soggy. Further it would attribute the potting soil to run over from the pot edges also.

As such, avoid over watering the moon cactus as that would make the cactus sit in soggy dirt.

Apart from that, you need to avoid watering the older moon cactus entirely during the winter season.

When I say older moon cactus, it would be one year and above aged cactus. Consider that you have young moon cactus, then you need to water them lightly during the winter season.


In terms of providing light for moon cactus, it is vital that you provide them bright and indirect sunlight for them to thrive well. 

Having said that, grafted cactus on the top could thrive in shade and they are not dependent on direct sunlight.

Moreover, the green stem cactus would require more direct sunlight. As such, you need to make sure that you provide the right amount of sunlight to the moon cactus to perform well.

When you grow them indoors, the best recommended place to locate them would be near a bright and sunny spot at your house.

In fact They would love to grow in room temperatures. Do not expose the cactus for too much heat as it could harm the cactus.

Consider that you live in an area where the USDA zone is 10 or 11, then you may grow it as an outdoor plant without any hassle.

You only need to locate them in  a bright location which has a partial shade when you have to grow them outdoors.  

Further, if you live in temperate climates, you could simply relocate the pots outdoors during summer.

When the temperature decreases during nighttime, you could shift the pots indoors.

On the other hand, if you are growing moon cactus as indoor plants, do not place them near cold drafts such as open-windows air conditioners and even at places where the plant will get direct heat as well.

Moreover, keep in mind that moon cactus cannot thrive in temperatures below 48 degrees Fahrenheit. (9 degrees Celsius).


You do not have to supply an excess amount of moisture for the moon cactus to thrive well. They would prefer to be in conditions where they get a moderate level of humidity.

Having said that, they could also thrive well in low levels of humidity as well. I would encourage misting the moon cactus also slightly as it would help to make the cactus stay healthy without making the soil wet.

You may not feed the moon cactus on a frequent basis as long as you are using a right soil mix.

Having said that, it is always best to feed the moon cactus once a month during their growing season as that would stimulate the grafted cactus to thrive well.

As such you could consider using an organic based cactus fertilizer whilst adhering to the labelled instructions.

When you feed, I would suggest you flush the soil as that would help to avoid the minerals build up in the soil.

Unless it would attribute the cactus to have a stunt growth. On the other hand, if you feed them too much that would also cause the cactus to deteriorate and turn yellow.

Moreover, avoid feeding the moon cactus during both winter and in fall.


Despite what you do to take care of the moon cactus, you would come across issues as aforesaid. As such continue to give them their essential basic growing conditions.

Consequently, they will grow well and  stay alive for a  longer period.  Growing moon cactus is fun and it would add so much beauty to your entire landscape.
