How do you take care of Strombocactus pulcherrimus?

Light Requirement 

It is vital that you expose them to full sunlight, preferably during the morning hours. Do not leave them exposed to direct sunlight especially in the intense hours of the day as it would not be healthy on the plants. 

Further, when you cultivate them as indoor plants, I recommend placing them near a bright sunny window spot. If you find it difficult to supply the essential sunlight levels, you could place grow lights closer to the plants. 

On another note if you had grown them indoors for quite a while and if you wish to bring them outdoors, best is to slowly accustom them to outdoor full sunlight. That is simply because it would otherwise result in the scorching of the plants.

Temperature and humidity

They are not the type of plants which would withstand the colder temperatures below 4 degrees Celsius.

The prolonged exposure to colder weather could even kill the plants. Hence be mindful to not expose them to such conditions at any given time. 

Strombocactus pulcherrimus would prefer to have warmer conditions right throughout. In terms of the right humidity levels, they would prefer to have moderate humidity levels. 

On the other hand, excess humidity levels would be harmful for the plants.

Is it cold hardy?

Strombocactus pulcherrimus are not cold hardy and they do not handle colder conditions well. They can withstand a colder temperature up to 4 degrees Celsius only.

Zone

Strombocactus pulcherrimus prefers to grow in USDA hardiness zone 9.

Watering Requirement 

Strombocactus pulcherrimus require only a minimal watering in general. To elaborate further on this, you may water them once every two weeks during spring and summer. 

Further you should water them only if their soil is dry too. You need to minimize watering the plants towards the mid-autumn. 

Further you need to skip watering them during winter as they would be literally in sleeping mode and would not consume any of the energy. 

As you may already know, you need to avoid over watering the plants as it would lead to unnecessary troubles.

Soil Requirement Type / pH

You could proceed with a commercially made cactus or a succulent soil mix to grow the Strombocactus pulcherrimus

They would consist of 20 % coarse sand. Strombocactus pulcherrimus would grow vigorously given that they get a well-draining and well aerating soil mix. 

Once you use a well-draining soil mix, it will not retain the excess moisture within the soil mix. Instead, they would tend to drain them away from the pot.

Unless it would create a soggy and waterlogged condition in the pot which would contribute to diseases such as root rot.

Where to Plant 

You could plant them both outdoors and indoors. However, when you plant them outdoors, you need to protect the plants from colder weather as they cannot withstand the colder conditions.

Fertilizer and time of year

You could feed the Strombocactus pulcherrimus with mineral fertilizers during early spring. Never feed them when they are dormant.
