How do you take care of Echinofossulocactus multicostatus?

Light Requirement

A plenty of sunlight would be optimal for the Echinofossulocactus multicostatus vigorous growth

Besides it is helpful for their typical spination as well. Having said that, you need to protect the plants from extreme sunlight during summer. 

Do not leave them under direct sunlight particularly during a heat wave. On the other hand, if you make them starve in sufficient sunlight, it will result in discolorations of the plants.

Further it would pave the way for root rot as well. A bright sunny windowsill would be perfect for them when you grow them indoors.

Temperature and humidity.

Moderate temperature ranging from -7 degrees Celsius to 10 degrees Celsius would be optimal for the Echinofossulocactus multicostatus healthy growth

If you have kept them in pots, you can keep them outdoors ideally in patios. With that being said, Echinofossulocactus multicostatus are responsive towards winds. 

Hence, I recommend locating them in a sheltered place. Once the temperature decreases up to -7 degrees Celsius, you can bring them indoors.

Is it cold hardy?

Echinofossulocactus multicostatus are cold tolerant up to -5 degrees Celsius. However, if you keep them exposed under frost for prolonged periods, it will create unhealthy impacts on the plants.

USDA Hardiness Zone

Echinofossulocactus multicostatus cactus are hardy in USDA hardiness zones 9a-11b ( -6.7 degrees Celsius ) – 50 degrees Fahrenheit ( 10 degrees Celsius).

Watering Requirement.

Echinofossulocactus multicostatus wants the soil to wither between two watering sessions just like the rest of other succulent and cactus. 

The ideal watering frequency should be once every 10 days generally during warmer months.  However, it may vary depending on the pot size and on the plant size. 

On the other hand, cut back on watering  once every two weeks during winter. Echinofossulocactus multicostatus are quite sensitive towards root rot. 

Hence if you have placed a drip tray around the plants, you need to empty them. High humidity levels pave the way for root rot. 

Without sticking to a schedule of watering, you need to always check on the soil condition and then apply water for the plants. 

If you find out the soil is dry, you need to immediately start watering them. Refrain from misting the plants. 

One might think that Echinofossulocactus multicostatus can survive with light watering simply because they are cacti type, but actually it is not. Instead, you need to give a thorough watering for the plants and let them dry afterwards.

Best recommended is to grow these plants in a mineral substrate. Besides, you may also use a  cactus soil mix or a succulent soil mix to grow them. . You can easily purchase them from your garden stores. 

The perfect soil mix needs to be well draining as well as well aerating so that it will allow the plants roots to grow healthily.

Pot size Potting and Repotting

When it comes to selecting the right pot for the Echinofossulocactus multicostatus, you can grow them in any kind of pot. 

Having said that, what would suit them the best would be the plastic pots. Plastic pots do not overheat faster. 

Further when they heat up also, it will keep the plants stay comfortable  right through the night. 

Moreover it needs to have a draining hole as well. Further you may also place some pebbles in the pot as it will give a visual impact for the specimen.

In terms of repotting the Echinofossulocactus multicostatus cactus, I recommend doing it regularly so that you can avoid any potential disease which could take place. 

However, when conducting repotting, ensure that you do not damage their roots as they are quite sensitive. Before repotting, ensure that their soil is dry. 

To start off, you need to first take the plant out of the pot and knock away the solder soil around the plants.

Next, inspect the plant closely to see whether you can spot any rotten or damaged roots. If you come across any rotten roots, snip them off and treat those with a  fungicide.

When those wounds are healed, you can plant them in a fresh soil mix. . Skip watering them  for about one week’s time and then resume watering them. That will allow the plants to get to the new growing conditions of the plants.

Where to Plant

You need to ideally select a place to plant them where they can gain sufficient sunlight. 

Besides, you need to be mindful of growing them in a well-draining soil mix as well. You can adhere to the aforesaid tips when selecting a pot for them.

Fertilizer and time of year

Fertilizing is helpful for the healthy growth of the Echinofossulocactus multicostatus cactus. You could feed them during early spring to early fall ideally. 

You may go ahead with a fertilizer which has a high potassium component to feed them. However, if you have recently repotted the plants, you do not need to feed them as they can absorb the nutrients from the fresh soil mix. Never fertilizer them during their dormancy.

Additionally, they could be susceptible to diseases as well.  Ensure that you inspect the plants closely so that you can see if there are any early signs of disease. 

I encourage repotting them once every two to three years so that it would allow you to closely monitor the plants.

You may either purchase the seeds or if you already have a Echinofossulocactus multicostatus cactus, you can obtain the seeds from that.

First you need to wait until they produce flowers and transform them into fruits. Once the fruits ripe, you can obtain the seeds. 

Once you obtain them, clean them and allow them to wither. The germination of the seeds is very easy and simple. Next,  arrange some  seeding mix in a shallow container which is covered with a lid. 

Next gently press the seeds in the soil without digging holes and planting them. Next simply tap the tray on a hard surface so that it can settle in the soil. 

Ensure that you are using a slightly moist soil mix for this purpose. Skip watering them for about two weeks’ time.

When you spot them germinating, you can take off the lid so that it will allow the plants to have a proper air circulation. 

I encourage using a seed mat so that the germination would be benefited from that. If you cannot provide proper sunlight, you may also place them closer to LED grow lights too.
