Taking Care Of Austrocephalocereus Estevesii

Ideal conditions

Austrocephalocereus Estevesii should be grown outdoors for two reasons – it requires partial to full sunlight to thrive, and it also grows up to 6 feet tall, though some cacti may grow even more.

Situated in the USDA hardiness zone 10a (30 to 35 degrees F/-1.1 to 1.7 degrees C), this plant isn’t cold-hardy. Given that this cactus is best to keep outdoors, you should keep it only if winters are warm in your area.

Watering

Water Austrocephalocereus Estevesii just like a typical succulent – only once its soil is dry to the touch. This cactus is drought-resistant and doesn’t require much water.

Make sure not to overwater Austrocephalocereus Estevesii – overwatering will lead to waterlogging and root rot.

In winter, suspend watering your Austrocephalocereus Estevesii cactus. Dormant throughout the cold months, cacti require very little water to survive. You may either keep this cactus completely dry or lightly water it once or twice per month.

Where to plant

Plant your Austrocephalocereus Estevesii cactus in light, fast-draining cactus soil. For extra drainage, you may also add coarse sand or perlite in a 1:1 ratio or more. 

To keep this cactus mobile, plant it in a pot that has large drainage holes at the bottom.

When young, the Austrocephalocereus Estevesii cactus may be kept indoors. But given its high light needs, you should place your Austrocephalocereus Estevesii near a window that receives direct sunlight all day.

On very hot days or during heatwaves, the cactus should be temporarily moved to a shaded location. This applies both to indoor and outdoor keeping.

As this cactus grows older and bigger, it will be more difficult to keep inside and move around. And at some point, you won’t be able to keep it inside at all. This won’t be a problem in warmer months, but it will be a problem in winter when the cactus should be kept inside to avoid freezing.

This is why Austrocephalocereus Estevesii is best to grow in areas where winters are mild and where you can keep the cactus outdoors all year long.

General care information

Austrocephalocereus Estevesii isn’t a slow grower, but for quicker and more consistent growth, you should fertilize it throughout the growing season (spring and summer). Fertilize the soil once every month or two with a cactus fertilizer diluted to half strength.

If you’ve just repotted your cactus, then fertilization may not be necessary since fresh soil is rich in nutrients.

Repotting, by the way, is another thing that you’ll have to do. Austrocephalocereus Estevesii gets quite big, and you may need to repot it into a larger pot every year. Even if your cactus doesn’t outgrow its pot, you may want to repot it anyway to inspect its roots and introduce it to fresh soil.

Repot your Austrocephalocereus Estevesii in spring or summer. Before repotting, allow the soil to dry, and after repotting, don’t water it for about a week.
