If you’re looking for a unique and interesting cactus to add to your collection, you might want to consider the Isolatocereus dumortieri. This cactus is native to Mexico and can grow up to 6 feet tall! It’s also relatively easy to care for, making it a great choice for beginner cactus growers.
Here’s everything you need to know about caring for and propagating Isolatocereus dumortieri.
Light and Temperature
Isolatocereus dumortieri does best in bright, direct sunlight.
If you live in a hot climate, make sure to provide some afternoon shade to prevent sunburn. This cactus can tolerate temperatures as low as 50 degrees Fahrenheit, so it’s perfect for growing outdoors in most parts of the country.
Watering and Humidity
This cactus is pretty drought-tolerant, so you don’t need to water it very often. In fact, overwatering is one of the biggest dangers when growing Isolatocereus dumortieri. Only water when the soil is completely dry – if unsure, err on the side of too little rather than too much water.
This cactus doesn’t like high humidity, so if you live in a humid climate you might want to grow it in a pot with drainage holes to help keep the roots dry.

1) How Do I Care for an Isolatocereus Dumortieri Plant
If you are lucky enough to have an Isolatocereus dumortieri plant, congratulations! This beautiful cactus is native to Mexico and can grow up to 15 feet tall in its natural habitat. In cultivation, it is usually much smaller, but no less stunning.
The plant has a slender stem with spiraling ribs and large, showy flowers that bloom at night.
Like all cacti, I. dumortieri needs bright light and well-drained soil. It is tolerant of a wide range of temperatures, but should be protected from frost.
Water sparingly, only when the soil is completely dry – too much water will rot the roots.
If you want to propagate your I. dumortieri, offsets can be removed from the main plant and replanted. Seeds can also be collected from the flowers (after they have been pollinated by bats or moths) and germinated in sterile potting mix.
Conclusion
If you’re looking for an interesting and unique cactus to add to your collection, consider the Isolatocereus dumortieri. Also known as the Bolivian torch cactus, this plant is native to Bolivia and Argentina. It’s a columnar cactus that can grow up to 20 feet tall in its natural habitat, although it will be much smaller if grown in a pot.
The green stems are covered in sharp spines, and the plant produces beautiful white flowers that bloom at night.
Isolatocereus dumortieri is not a difficult plant to care for, but there are a few things to keep in mind. First, it needs well-draining soil and plenty of sunlight.
Water only when the soil is dry – too much water will cause the roots to rot. During the winter months, reduce watering even further. Secondly, be careful when handling this cactus – those spines are sharp!
If you do get pricked, wash the area with soap and water to prevent infection.
If you want to propagate Isolatocereus dumortieri, the easiest way is from stem cuttings. Allow the cuttings to callous over for a few days before planting them in well-draining soil mix.
Keep them warm and moist until they start to root (this could take several weeks). Once they’ve rooted, you can treat them like any other cactus – give them plenty of sun and don’t overwater them!
