Are you looking for a stunning addition to your home or garden that's both low-maintenance and visually striking? Look no further than the blue barrel cactus, also known as 'Ferocactus glaucescens,' a vibrant member of the Ferocactus genus!  

It is a slow-growing cactus that looks like something out of this world! This bluish-green globular or rounded barrel cactus is usually solitary and covered in clusters of long, light-yellow spines. And get this: barrel cactus grows up to 22 inches tall and 20 inches in diameter! As it matures, it becomes columnar but still maintains its well-marked and slightly wavy ribs. 

The blue barrel cacti's crown is where all the magic happens—from spring to late summer, funnel-shaped yellow flowers are followed by round white fruits. And let's not forget about its fancy Latin name, "glaucescens," which means somewhat glaucous, basically referring to its stunning grey-blue coloration.

This blue barrel cactus has a similar barrel-shaped body to golden barrel cactus, but the main difference is the bluish-green color of the blue barrel cactus. Don't let its exterior fool you - this blue cactus is surprisingly easy to care for and can even thrive in less-than-ideal conditions.  

So, let's get started and discover why Ferocactus glaucescens is such a beloved houseplant!

Watering Needs 

Like all cacti, the blue barrel cactus is drought-tolerant by nature, and its spherical, water-storing stems can hold a lot of water.  However, their root structure is easily susceptible to overwatering, so make sure that you don't overwater, as it can lead to root rot and fungal infections.  

When the Ferocactus species is dormant in the winter, water it less, soaking it completely.  In spite of the right watering frequency, cactus roots can be damaged if the soil is not fast-draining.  Let the soil dry out thoroughly between waterings. 

Light Requirements 

Like many other cacti, the blue barrel cacti also require bright, direct sunlight to thrive.  These cacti require at least six hours of strong light each day to survive, although partial shade in the afternoon is often preferable, especially in hotter climates where the plant might become stressed by the intense heat of the afternoon sun.  

If you are growing Ferocactus glaucescens indoors, it is important to provide it with as much bright, indirect light as possible. You may need to supplement with grow lights to ensure that the plant receives enough light to grow healthy and thrive. If you are growing the plant outdoors, be sure to place it in a location where it will receive plenty of direct sunlight throughout the day. 

It's crucial to place your blue barrel away from any areas with constant direct sunlight, as doing so could result in burned foliage.  

Optimal Soil & Fertilizer Needs 

The blue barrel cactus likes very airy, porous, nutrient-rich soil with a pH of 5.6–6.7. Cacti require fast-draining soil that dries completely between waterings. Your soil must have a sandy texture and a low water-holding capacity, just like desert soil. Soggy, wet soil can damage your cactus and contribute to bacterial and fungal rot. In addition, because of a lack of oxygen, soggy soil substitutes air pockets with water, resulting in an anaerobic environment that can kill your plant. 

 As an alternative, you can create your own potting mix by combining equal portions of perlite, coarse sand, and good natural potting soil. Ideally, you want to use our specialized potting mix that contains organic mycorrhizae to promote the development of a strong root system that helps your cactus thrive.

Natural fertilizers with an equal amount of 5-10-5 (NPK) are the best choice, as they last longer and keep your soil alive by adding other beneficial compounds and microbes that encourage plant health and nutrient absorption. So, skip those harsh chemicals and give your cacti some love with a good natural fertilizer! 

Hardiness Zones & More 

Typically grown in hot, arid desert regions, the blue barrel cactus thrives indoors in warm, dry surroundings. Remember, if the blue barrel cactus is exposed to frost, it may suffer damage or even die. 

If you live in USDA regions 9 to 11, you can also grow these cacti outdoors year-round, as they are very cold- or frost-tolerant, so you should plant them outdoors or put them in a pot and move them indoors during the winter if the temperature drops below 25 F.

Keep your blue barrel away from cold, drafty windows and air vents if you are growing it indoors in a cold climate.

Pets & Common Problems of Blue Barrel Cactus

The blue barrel cactus is generally a hardy and disease-resistant plant, but it can be susceptible to a few common pests and problems.  

The common pests & problems are:  

Mealybugs: These can infest the plant and cause damage. To control mealybugs, you can use a cotton swab dipped in rubbing alcohol to remove the bugs from the plant. You may also need to use a commercial insecticide to control the infestation. 

Root rot: This can occur if the plant is overwatered or if it is planted in soil that does not drain well. To prevent root rot, be sure to allow the soil to dry out completely between waterings and use a well-draining soil mix.  

Sunburn: This can cause if it is exposed to too much direct sunlight. To prevent sunburn, be sure to acclimate the plant to direct sunlight gradually and provide it with some shade during the hottest part of the day. 

Blue Barrel Cactus FAQs

How do you take care of the blue barrel cactus? 

The blue barrel cactus is a slow-growing cactus that requires bright, direct sunlight and well-draining soil to thrive. It is important to allow the soil to dry out completely between waterings to prevent root rot and to avoid exposing the plant to freezing temperatures which can thrive in USDA zones 9-11.  

Overall, it is a low-maintenance plant that requires minimal care and attention, making it a great choice for beginner gardeners or anyone looking for a hardy and attractive addition to their collection. 

What is the difference between the golden and blue barrel cactus? 

Echinocactus(Golden barrel cactus) and Ferocactus (Blue barrel cactus) are two different genera of cacti that are similar in appearance but have some notable differences.

The golden barrel cactus has a more globular shape, while the blue barrel cactus tends to be more cylindrical or barrel-shaped. Echinocactus also tend to have more prominent ribs and spines than Ferocactus, which have fewer ribs and spines that are often more curved.  

Additionally, Echinocactus tends to have more colorful flowers than Ferocactus, which produces smaller, less showy flowers. Overall, both genera are hardy, low-maintenance plants that are well-suited to arid growing conditions, but they have some distinct differences that make them unique. 

How often do you water a blue barrel cactus? 

Blue barrel cacti are drought-tolerant plants that require watering for about 2-3 weeks during the growing season (Spring-summer). It is important to use a well-draining soil mix and avoid getting water on the stem or leaves of the plant.  

It is also important to avoid watering during the winter months, as the plant goes dormant and does not require as much moisture. It is best to err on the side of underwatering rather than overwatering to prevent root rot and other issues. 

How long does it take for Ferocactus to grow? 

Ferocactus is a slow-growing cactus that can take many years to reach its mature size. The exact growth rate of Ferocactus can vary depending on factors such as the plant's growing conditions, age, and species.  

In general, however, it can take anywhere from 5 to 15 years or more for a Ferocactus to reach its full size, which can range from a few inches to several feet tall. During this time, the cactus will produce new spines and ribs and may also develop flowers and fruit once it reaches maturity.
