Taking Care Of Ferocactus Glaucescens “Blue Barrel Cactus”

Ideal conditions

Reaching 18 inches in diameter and over 1 foot in height, Ferocactus Glaucescens “Blue Barrel Cactus” is perhaps the best to keep outdoors for unimpeded growth. What also makes outdoors an optimal location for this cactus is its high light requirements.

The Blue Barrel Cactus is also fairly cold hardy, being able to survive in temperatures down to 25 degrees Fahrenheit (-3.9 degrees Celsius). With that said, you should not expose this cactus to winter cold and bring it inside to prevent it from freezing.

Watering

Water your Ferocactus Glaucescens “Blue Barrel Cactus” only when its soil is dry to the touch. The Blue Barrel Cactus is drought-resistant and doesn’t require much water to thrive.

Be very careful with the amount of water supplied to this cactus – like many other cacti, the Blue Barrel Cactus can develop root rot if exposed to standing water in the soil.

In winter, suspend watering the Blue Barrel Cactus or only lightly water it once or twice per month. Cacti get dormant in winter and require much less water than in summer.

Where to plant

Ferocactus Glaucescens “Blue Barrel Cactus” should be planted in a fast-draining cactus mix so that water has no chance of accumulating inside. For extra drainage, you may add perlite or coarse sand to the soil in a 1:1 ratio, as well as use a pot with large drainage holes at the bottom.

Since the Blue Barrel Cactus requires partial to full sunlight, it should be kept outdoors. However, you may keep it indoors as well if you have a window sill that is directly lit by the sun.

Whether inside or outside, be sure to temporarily move this cactus to a shaded location on extremely hot days.

General care information

You should fertilize your Blue Barrel Cactus throughout spring and summer for optimal growth. This cactus is a slow grower, and fertilization might allow for steadier growth, especially in older soil that has a low nutrient content.

Fertilize your cactus with a cactus fertilizer mix diluted to half strength. Feed the soil with the fertilizer once every month or two.

If you want your Blue Barrel Cactus to grow big, then you should repot it frequently, perhaps every year in the spring or summer. If restricted in a small pot, the Blue Barrel Cactus won’t grow to its natural size.

Another benefit of frequent repotting is that you get the chance to have a look at the cactus’s root structure and remove any damaged or rotten parts. Besides, reintroducing the cactus to fresh soil may be beneficial to its growth.

Before removing the plant from the pot, allow the soil to dry for easier removal. And once the cactus is in its new pot, don’t water it for a week to allow it to recover from stress.
