Welcome to the Bolivian torch cactus, or Achuma, also known as Trichocereus bridgesii- a stunning perennial, evergreen cactus that's bound to leave you in awe! In 1974, Friedrich and Rowley merged the genus Echinopsis, reclassified Trichocereus bridgesii to Echinopsis lageniformis. It also has its mutated and unusual variety Trichocereus bridgesii' montrose'. 

This fast-growing columnar cactus has a light green exterior and is easy to care for. This perennial evergreen cactus is sure to impress and makes it perfect for even the busiest gardener. The spines are not just plain old boring brown but can range in coloration from honey-colored to brown, adding an extra pop of excitement! 

This Bolivian torch grows tall like a tree and can reach heights up to 16 feet. If you're lucky enough, you may even glimpse its large white night-blooming flowers blooming in summer!  

Don't get confused with Echinopsis bridgesii though; it's a totally different plant than our beloved Bolivian Torch Cactus 'Trichocereus bridgesii'. This amazing plant is easy to grow for any aspiring gardener because it can be propagated by cuttings or seeds, and its fruit is completely edible. 

Watering Needs 

If you're a cactus enthusiast, you probably already know that excess water is the one thing that cacti do not like. Beginners frequently make the mistake of overwatering their cacti to the point of creating a mini-DIY swamp. Being native to arid, desert-like regions, the Trichocereus bridgesii is a drought-tolerant cactus that doesn't require frequent watering. It's best to wait until the soil is completely dry before watering it again.  

Overwatering can lead to root rot, which can cause fungal infections or other diseases. Early spring and autumn are good times to water the younger plants, but the Bolivian cactus require less in the winter as they go dormant. During the hotter summer months, you can water frequently, but you shouldn't leave the plant soaking in still water. 

Light Requirements 

Trichocereus bridgesii prefers bright, indirect sunlight and can withstand full sun exposure. However, it's important to avoid exposing the plant to direct sunlight during the hottest part of the day, as this can cause the plant to become sunburned. So, gradually increase the exposure until it can handle the full sun. If you notice any signs of sunburn on it, move it to a location with less intense light. 

If you're growing the plant indoors, place it near a south-facing window or under a grow light to provide it with enough light. If you're growing the plant outdoors, make sure it's in a location that receives at least six hours of sunlight per day. 

Optimal Soil & Fertilizer Needs 

Trichocereus bridgesii favors very airy, sandy soil that drains well. Planting them in ordinary soil will result in compacted roots, stunted growth, and most likely root rot. Instead, make or buy a well-draining potting mix, or ideally use our specialized potting mix that contains over 5 natural substrates and mycorrhizae to promote the development of a strong root system that helps your Bolivian torch cactus to thrive.  

Ideally, you should look for a natural fertilizer with an approximate blend of 5-10-5 that is higher in phosphorus than nitrogen. The best choice is to use a Natural Organic fertilizer as they last longer and keep your soil alive by adding other beneficial compounds and microbes that encourage plant health and nutrient absorption.  

Hardiness Zones & More 

Trichocereus bridgesii is native to the high deserts of Bolivia and can tolerate a wide range of temperatures. It's hardy to USDA zones 8-11, which means it can tolerate temperatures as low as 20-30°F. 

However, it's important to protect the plant from frost, as prolonged exposure to freezing temperatures can damage or kill the plant.  If you live in a colder climate, it's best to grow the plant in a container and bring it indoors during the winter months. If it has already been damaged by frost, it's best to wait until the weather warms up to prune any damaged or dead tissue.
