A plant that originates from Africa – this article will introduce you to the life of Euphorbia Submamillaris succulent – also known as the Euphorbia Monstrose succulent. More specifically, this article will give current and potential owners a more profound understanding and recommendations for how to care for their Euphorbia Monstrose properly. Like all Euphorbia succulents, Euphorbia Monstrose is pretty simple to care for with just a couple of small steps. However, before we dive into that portion, let us get to know the plant a bit more.

As you may have gathered thus far, the Euphorbia Monstrose plant is a species of the many Euphorbia succulents from the Euphorbiaceae succulent family. This succulent is very similar to a cactus in its appearance and the prickles it holds on each of its stems. The only significant difference is that it is essentially mini cacti bundled together in a group rather than a singular stem like most standard cacti have. In addition to the succulent’s cacti-similarities, this Euphorbia Monstrose also tends to bloom yellow-colored flowers on smaller stems that come off the cacti-like stems. Overall, healthy, grown Euphorbia Monstrose succulents can reach under four inches tall, with seven rib-like textures on each stem.

  • Sunlight: receives plenty of direct, bright sunlight.
  • Watering: Minimum water use.
  • Temperature: do the best in warm temperatures.
  • Growth Season: Summer.
  • Propagation: easily propagated from trimmings.
  • Soil: requires a specific soil mixture with half pumice and half sand.
  • Fertilizer: this is helpful in case the plant suffers from a disease.

Euphorbia Monstrose Care

Growing Season of Euphorbia Monstrose

These succulents are best planted during the summertime when temperatures are warm outdoors. This also tends to be the same seasonal time when the flowers begin sprouting. Of course, it is helpful to keep in mind that Euphorbia Monstrose dormancy typically begins around the same time that winter begins – at this time, your succulents’ growth will be much slower until the warmer temperatures come around again.

Soil Requirements 

Like most succulents, these Euphorbia Monstrose succulents require a specific soil mixture. Along with being a soil that drains excess water well, the soil provided should always be mixed with half pumice and half sand. This makes for a lower chance of the soil soaking up too much water, as well as a lower chance of root rot occurring. 

Sunlight Requirements 

Always be sure that your succulent receives plenty of direct, bright sunlight. Although most succulents do better with indirect sunlight, this species flourishes more in direct sunlight. Whether you plant your Euphorbia Monstrose indoors or outdoors, it should always receive at least five hours of sunlight per day. 

Temperatures and Humidity

As I mentioned prior to this part, these succulents are better in warmer temperatures rather than cold. They should never be exposed to temperatures under 50 degrees Fahrenheit, as they cannot withstand frost. In addition to that, these succulents love some humidity because it is a healthy addition to their growth.

Healthy Watering

Keep in mind that succulents tend to be more prone to root rot from overwatering and other underwater diseases. To stay beyond this and keep such events from occurring, it’s essential to understand what is healthy for your plant and develop a safe watering routine. For instance, these succulents should only be watered once a week unless you notice they may need more. Sometimes, a light water spray is more beneficial than actual watering. If you’re ever stuck on whether or not to water it again, refer to the soil’s moisture – if it’s dry, water it or spray it lightly; otherwise, leave it be for a few more days.


Euphorbia Monstrose doesn’t need to be fertilized as it won’t make them grow any faster due to its slow growth. However, fertilizer is essential if and when succulents suffer from pests or diseases. In this case, a simple repotting (either yearly or as needed) will suffice.

Potential Pests & Diseases

These succulents rarely ever attract pests due to their features. More specifically, the cactus-like prickles and poisonous sap. However, there is always a possibility of some mealybugs making an appearance, especially if your Euphorbia Monstrose isn’t healthy. As far as diseases go, the most common disease you will find is root rot.


Propagating Euphorbia Monstrose

The best (and easiest) way to propagate your Euphorbia Monstrose succulent is by using trimmings from the parent plant. Doing so is simple and doesn’t take long at all. To propagate your Euphorbia Monstrose with this technique, thoroughly clean your gardening shears.
Now you can trim off the parent plant – but you should never trim close to the bottom of the plant. Trim off the part you desire to use, leaving a little bit of the stem intact with the trimming. Let the trimmed parts dry thoroughly. Then, plant the trimming and water the soil using the appropriate soil.

As you now know, Euphorbia Monstrose succulents are a simple plant to own. They’re also unique! This plant will grow on you and become a top favorite, from the minimal care requirements to the incredibly appealing mini cactus-looking appearance. Now that you’ve discovered how to care for a Euphorbia Monstrose, would you ever purchase one?
