How do you take care of Epithelantha micromeris?

Light Requirement

Epithelantha micromeris have strong requirements when it comes to sunlight as only then they could grow to their best potential. 

Epithelantha micromeris are strong sunlight lovers. In fact, they will enjoy full direct sunlight. I suggest growing them outdoors due to this requirement.

Having said that, you can also grow them indoors as well. You may choose a bright sunny spot to plant them. They can also grow well in partial sunlight. 

So, when you select a place to grow them, it should be a place where they can gain both full sunlight and partial shade. 

Ideally it needs to be a place where they can absorb morning direct sunlight. Be mindful of that. Furthermore, if you wish to supplement the indoor sunlight, you could place grow lights closer to the plants.

Temperature and humidity

You need to be mindful of the temperature and the humidity aspect of these plants as proper temperature and humidity levels are crucial in having a firm growth of Epithelantha micromeris

Warmer temperatures right throughout the year is what these plants need. However, they can withstand the subzero temperatures as well. 

In fact, they can tolerate colder temperatures up to 20 degrees Fahrenheit (-6.7 degrees Celsius). However, these are not frost hardy plants. 

So, do not leave them exposed to the colder temperatures for too long. I recommend growing them indoors during colder times to protect the plants from such unhealthy conditions.

Is it cold hardy?

Epithelantha micromeris cannot withstand the colder conditions for too long as aforesaid.  


Epithelantha micromeris grow well in USDA hardiness zone 9a where the minimum temperature would be 20 degrees Fahrenheit ( -6.7 degrees Celsius).

Watering Requirement

Watering is the most critically important factor in terms of taking care of these plants well. In other words, if you do not want to kill the plants, you should refrain from over watering them. 

Epithelantha micromeris especially are quite sensitive towards over watering as it would pave the way for root rot. 

If you are a succulent lover, you know how severe the repercussions of the root rot would be. Epithelantha micromeris are adapted to grow in hot and dry conditions which literally reflect on the fact that they just don’t like wet feet. 

So, they can perform well with minimum water. If you wish to have a healthy growth of your precious Epithelantha micromeris, you should never leave their feet in soggy soil.

To refrain from over watering the cactus, you need to always check the soil condition first and then apply water. 

Literally, if the soil is dry, you can water them. On the other hand, if it is moist, you need to refrain from watering them for a couple of days.

Always ensure that you let the substrate wither between two watering sessions. However, if you accidentally pour water on them, you need to immediately let them as unless it would be harmful for the plants.

Soil Requirement Type / pH

Epithelantha micromeris perform well if you provide a substrate which is excellent draining. 

Having excellent drainage is the most crucial factor when selecting the right soil mix to grow them so that it would allow the excess moisture to move out from the pots without retaining them in the pot. 

If you wish to make a fast-draining soil mix, you can make a mix of potting soil, turface and crushed granite. When you add crushed granite, it would allow the substrate to have a proper aeration too.  

Pot size Potting and Repotting

I encourage growing the Epithelantha micromeris in terracotta pots as they are high in porosity. 

The porous pot materials would suit them the best as it would allow the excess moisture to drain away from the pots. In addition to that, the selected pots need to have a generous drainage as well.

Consider repotting them once every two years. You do not need to repot them often as these are slow growing plants. 

However, when you repot them once every two years, it would allow the plants to grow freshly and vigorously. 

If you keep growing them in the same pot, the nutrients would be depleted. So, once you repot them freshly, it would allow the plants to gain nutrients freshly.

Where to Plant?

Epithelantha micromeris are not tolerant of colder conditions. As such you need to keep that in mind and then select a spot where the plants will not be exposed to these frost conditions. 

If you are someone who goes through these conditions, best is to grow them indoors. Or else you could plant them in containers and place them outdoors during summer and bring them indoors during winter. 

If you live in the aforementioned zones, you can choose a place where they can gain partial shade during the hottest hours of the day and full sunlight during the morning hours. If you want to grow them indoors, choose a bright sunny windowsill.

Fertilizer and time of year

Fertilizing would be effective in stimulating vigorous growth in the plants.Best would be to feed them during their active growing season. 

In terms of the fertilizing frequency , you may feed them twice or thrice a year in spring and summer. Further best is to proceed with a mild fertilizer for this purpose.

Common bugs and illnesses

Epithelantha micromeris are somewhat resistant to pests attacks usually. However , they may be susceptible for regular pests’ attacks from aphids, mealybugs and for scales as well. 

These pests would be quite attractive towards these plants particularly if there are favorable conditions for them. In addition to that, excess moisture could pave the way for over watering, and it will end up creating root rots in the plants. 

If root rot gets severely spread, chances are that your precious Epithelantha micromeris may die too.

Special Care tips

How to propagate Epithelantha micromeris?

Propagating the Epithelantha micromeris is not that hard. You may simply use seeds or their seeds to propagate them. Further you may also use the division method to propagate them.

If you wish to use the stem cutting propagation method into practice, you need to simply remove the offset from your plants using a sterile knife. 

Next, set it up in a dry place which will allow them to develop callus. When they develop callousness, you may simply go ahead and plant them in a fresh soil mix. 

After a few weeks’ time, you could continue with the regular care treatment for them. If you wish to use the seeds propagation method you could do it indoors.

However ensure that they get adequate sunlight there. Further I recommend using a seed mat as that will increase the success of the propagation.
