What Are Myrtillocactus Geometrizans?

Myrtillocactus Geometrizans are part of the cacti family and grow up to thirteen to fourteen feet in height. Stems are compact and resemble dense clusters when mature. The blueish gray color may also appear greenish-white sometimes. The stems grow into two to four inches diameter width and have thorns on their ribs.

Myrtillocactus Geometrizans Care

Myrtillocactus Geometrizans are succulents that are easy to care for as they like drought-like growing conditions. Let us look at their requirements to master the art of growing these wonderful beings at home.

– Water Requirements

Myrtillocactus Geometrizans store moisture as a cacti. You do not need to water them every day or even weekly. In summers, water them regularly, but that does not mean every single day. Let the soil completely dry out in between watering. 

It can take several days for the soil to dry out. Do not worry. The plant has great abilities to survive a missed watering day or more. In winters, slow down on watering.

Monitor its growth and look at its stems and branches in winters. If they begin to shrivel, it means they need frequent watering. Is this not great? I think, as a gardener, such plants are a fantastic addition to the garden.

– Soil Requirements

Myrtillocactus Geometrizans like well-drained soil. Pick a ready-made soil for cacti from the market or build your own. Keep in mind that the potting soil must never remain moist or wet. Add some gravel to make the potting mix even more porous and well-drained.

Gravel helps in water filtration too. It will aid in keeping the soil loose and dry while allowing the roots to absorb as much water as they need. It will prevent root and plant decay.

Myrtillocactus Geometrizans soil must encourage aeration too. For this purpose, keep the soil structure porous. 

– Light Requirements

Myrtillocactus Geometrizans like to be in direct sunlight in summers. They may need to be protected from frost, cold wind while keeping them warm and protected during winters.

Winter is the time for them to hibernate. They will bloom in spring only if they have rested well during winters. Make sure you give it plenty of light in winters too.

When the plants are young, they need partial shade. Keeping it sheltered from light allows them to gain strength. Once they mature, you can keep them in full sun, and they will love it.

– Temperature Requirements

Myrtillocactus Geometrizans’ temperature requirements are the same as those of plants from the Mediterranean climate. The temperature drop from 25 degrees Fahrenheit is not favorable for the plant. 

Try not to let the temperature drop below 50 degrees Fahrenheit in winters. Maintaining temperature is a matter of concern only in winters. Summer heat is tolerated well by Myrtillocactus Geometrizans.

– Humidity Requirements

Myrtillocactus Geometrizans are drought-tolerant, but high humidity is not suitable for them. Low humidity conditions are favorable because they keep the branches and stems protected from wilting.

Remember, the Myrtillocactus Geometrizans is a cactus, and it stores water in the fleshy stems. We must never overwater it, put it in the shade, or mist the plant. The ideal humidity level should be around thirty percent.

– Fertilizer Requirements

Myrtillocactus Geometrizans hibernate in winters and hence don’t need fertilizers in winters. In summer or spring, when the plant begins to grow, it needs a boost. 

Any fertilizer with higher phosphorus than nitrogen is best. 5:10:5 is the balance that you are looking for. This ratio represents nitrogen, phosphorus, and potassium portions in any ready-made fertilizer. You can always use compost and any other natural or organic fertilizers for your Myrtillocactus Geometrizans plants.


Propagation Guide

Myrtillocactus Geometrizans propagation can be done by using seeds or through stem cuttings. It is done throughout the growing season and never in winters. Before we discuss propagation methods in detail, let us look at their growing habits. 

– Growth 

Myrtillocactus Geometrizans are quick to grow to their mature levels. You will know that they are mature enough when you see a dense population of closely grown stems. In terms of how long they take to mature, you will not need to wait too long. Growth rates are steady, and within a few months, you can already see noticeable development. 

Myrtillocactus Geometrizans fast-growing cactus is a novel indoor plant, but it can also grow outdoors in USDA hardiness zones 9a to 11b. When planting outdoors, be sure to protect your plant during chilling nights and frost. You may have to cover it if the temperatures get too low for it or if it snows.

– Potting 

To pot Myrtillocactus Geometrizans, have a roomy pot on hand and add the soil in. It is best to make sure the pot has holes at the bottom to guarantee well drainage of water from the soil and sufficient aeration throughout the lifecycle of the plant.

It will also help leave space for more stems to grow over time. Only use this trick if you manage water well. In case you have doubt, shift the plant each year into a pot that is two inches bigger than the previous one. 


Before you think about propagating your blue candle cactus, make sure the winters are over. Do the following tasks in spring or summer and never in winters.

Planting Myrtillocactus Geometrizans Seeds

Take seeds from the ripe berries, wash, and dry them. Next, plant them in the sandy soil. Keep watering them regularly. Place the pot in the sunlight to promote sprouts.

– Stem Cuttings

Here is a step-by-step guide for propagation through stem cutting:

  • Make a cut using sterilized scissors or a knife
  • Select a mature branch
  • Allow the cutting to dry out and form callous for a couple of days
  • Plant it in a potting mix suitable for the plant

It can take three or more weeks to see the growth. It is best to propagate your plant from stem cutting in spring or summer. Temperature higher than 65 degrees Fahrenheit will aid in the new growth.


Myrtillocactus Geometrizans is a self-sustaining and drought-tolerant plant. It may still have specific problems while adapting to pot culture.

One of the main problems the Myrtillocactus Geometrizans plant faces is restricted growth in pots. They do not get enough space to grow and expand in containers sometimes. Stems growing close together may poke into each other and fight for space. It can be avoided if plants are repotted timely. 

Lack of sunlight also affects its growth. It is crucial to provide it with enough light to thrive. Myrtillocactus Geometrizans need full direct sun and can live in the partial sun too.

If you have long winters, then this could be a problem for you. Consider installing indoor lights for this plant.
