How do you take care of Melocactus intortus?

Light Requirement 

You should ensure that you leave them under full sunlight so that it will allow them to grow to their fullest. 

Literally, ensure that you expose them for at least six hours of sunlight preferably in the morning hours. When you grow them as indoor plants, place them near a bright sunny window. 

When it is summer, you can bring them outdoors and expose them to some direct sunlight. However, when you bring them outdoors, make sure that you do it gradually. Unless it would make them traumatized.

Temperature and humidity

Melocactus intortus do not tolerate colder weather. Hence ensure that you expose them for temperatures above 8-12 degrees Celsius always. 

The exposure to frost can even result in the death of the plants. When you grow them indoors, do not place them closer to cold drafts as it could also cause changes in humidity. 

Having said that, humidity is not something which you should worry about as long as you grow them in a soil medium which has excellent drainage.

Is it cold hardy?

USDA Hardiness Zone

Melocactus intortus preferred USDA hardiness zones are 10-11.

Watering Requirement

Melocactus intortus would thrive well with moderate watering. If you feel like their soil is dry, you can consider watering them. 

If you wish to still ascertain whether their soil is dry, , you can simply place your finger in the soil and check the status of it. 

If you feel like their soil is moist, you need to wait for a couple of days and then water. Do not ever let their soil become bone dry as they cannot withstand long stretches of dryness. On the other hand,over watering could result in diseases such as root rot. 

Soil Requirement Type / pH

It would be beneficial for the Melocactus intortus’ optimal growth if you provide a sandy or rocky soil mix for them. Additionally it has to be a well draining soil mix. 

if you grow them in a poor draining soil mix, it will result in root rot. Moreover, it would make them more vulnerable for other bacterial infections as well. 

If you grow them as container plants, you may go ahead with a well-draining cactus potting mix. When it comes to the right ph. of the soil mix, best would be to provide a soil mix which is acidic to neutral.

Pot size Potting and Repotting

A pot which has good drainage would be ideal to grow the Melocactus intortus

Moreover, consider growing them in a porous material pot as they would evaporate excess moisture faster. 

I recommend using Unglazed clay pots for them. I recommend growing the plants in slightly larger pots than the plants root ball.

When it comes to repotting, you may conduct it once every two years. Melocactus intortus have a weak root system and they find it difficult to establish due to that. 

If you spot the plants have outgrown from the pots, you can consider repotting them. If you consider repotting them, I suggest you wait until spring comes, as it would be beneficial for the optimal growth of the plants. 

You can simply follow the same steps that you do repot other cacti when repotting these plants. However keep in mind that you need to plant them in the same depth as initially when you plant them freshly in the new pot.

Where to Plant 

Melocactus intortus have strong requirements when it comes to light. Hence when you grow them in a place, ensure that you ensure they can absorb sufficient sunlight.
