Ferocactus glaucescens aka Blue Barrel

Blue Barrel is a low-maintenance plant that requires minimal attention, making it an excellent choice for beginners.

Blue Barrel does best in dry soil and should only be watered sparingly.

When it comes to the Blue Barrel, a potting soil that is too moist can cause problems. For this reason, it's important to use a soil mix that is well-draining and does not retain too much moisture. A soil that includes perlite or vermiculite for drainage and organic matter for nutrition is ideal. You can achieve this by simply adding a few scoops of perlite to your store-bought cactus soil.

Blue Barrel requires abundant, bright and direct light. Placing it less than one foot from a window is the best way to make sure the plant receives enough light to survive and thrive. Depending on your region, however, the current weather can affect the placement of the plant in your home. For example, in some areas the sun may be too direct and intense, so it's best to place it farther away from the window. You may also need to adjust your placement according to the season as the sunlight can change intensity over the course of the year. If you live in a region with significant temperature fluctuations, such as a desert, you may need to place the plant a bit farther away from the window to avoid extreme heat or cold. With some care and attention, your Blue Barrel will be sure to bring you many years of beauty and enjoyment.

During the cold period, it is common for Blue Barrel to go dormant and their growth may slow down, so waterings should be spaced out more during this period.

Ploi's records do not contain confirmed information on the toxicity of this particular plant. In the event of accidental ingestion of plant material with questionable toxicity by you, a family member, or a pet, it is always a good idea to consult a healthcare professional.

Blue Barrel enjoys dry environments, but misting the plant or providing extra humidity can create an environment for harmful fungi to thrive on the leaves.

The growth of Blue Barrel is not rapid and it doesn't necessitate any extra fertilization. By replacing its potting soil once a year, it should receive ample nutrition. It is important to note that plants obtain their energy from the sun's rays, not from fertilizers.

Blue Barrel’s native range is Southwestern United States and Mexico.
