The crested cactus may not bloom because its a crested cactus - some just don't. If the one on the left is a Golden Barrel it is way too small (ie. young) to flower. If it was some regular Ferocactus it might be a question Read more
Ferocactus thrives in poor and arid soil. Water the cactus at the time of planting to anchor it into the soil. Water again only if the weather in your area is unseasonably dry and if normal spring or winter rainfall does not occur.
Hailstorms cause white areas that look like polka dots where the impact of the frozen hailstones struck the skin of a barrel cactus with enough force to kill the tissue. Often damage is just on one side of the cactus, where the wind drove the Read more
The Ferocactus, are globular plants with very long spines (about 5-7 cm), up to 1cm wide and curved. They live in the deserts of California and Baja California, some areas of Arizona, southern Nevada and Mexico, so in general they can tolerate frosts down to Read more
This arid plant likes high temperatures and low humidity. It will thrive in temperatures above 75°F, but avoid consistent temperatures below 40°F. Keep it indoors on a sunny windowsill during cooler months.
Ferocactus glaucescens inermis prefers direct sun with partial shade during the harshest afternoon hours. It will not tolerate full shade. They thrive in late afternoon sun.
The cactus naturally grows in low fertility areas so their nutrient needs are low. Fertilize the barrel cactus once a year in spring when it leaves dormancy and begins growing again. A low nitrogen liquid fertilizer is a good formula for the barrel cactus.
Yes it is a fungus , but not a harmful one , it is a "sooty mould " living on the sap that the plant secretes , and is common on plants such as Ferocactus . In the wild it would tend to washed off Read more
Growing Conditions Soil: Plant your cactus in early spring before new roots begin to form. The roots may appear dry, but that is typical before new growth begins. Dig a hole deep enough for the plant's roots and amend it as needed to provide fast-draining Read more
This happens when the soil is too wet or the cactus is planted too deeply. Barrel cactus plants should be planted so that the roots are firmly pressed into the soil, but without any soil piled up around the base of the cactus. Natural rainfall Read more

Characteristics: Ferocactus glaucescens is a slow-growing globular cactus that grows up to two feet tall and wide. As the cactus matures, multiple heads can be produced, to form a thick mound (1).
If you snap in half the one-inch needle of a Ferocactus, however, don't expect it to get replaced. The plant probably doesn't even “know” that the spine is damaged – all that tissue was already dead, the only living part of the spine lives at Read more
Plant F. chrysacanthus in porous cactus soil or gravel; the point is to allow for the best possible drainage. On that note, if you are growing this cactus in a container, be sure it has drainage holes. Water the cactus sparingly.
Highly modified spines functioning as extrafloral nectaries in Ferocactus emoryi. Seemingly normal spines of Harrisia pomanensis secreting nectar. They secrete a form of nectar which ants find irresistible.
Pollination experiments revealed that this species is self-incompatible and xenogamous. In natural conditions, fruit set was 60% and cross-pollination fruit set was 100%.
The soil should be dry when you repot barrel cacti and the container should be slightly larger than the plant. Watch for infestations with scale insects, mealybugs, or spider mites. Rot is only a minor problem and as long as your cacti are watered and Read more
Ribs are densely armed with areoles composed of 7-9 central spines (1 of which is longer than the rest, thick, flattened and hooked at the tip) and a varying number of whitish to grey radial spines depending on age. Funnel-shaped flowers are composed of yellowish, Read more

2. Barrel Cactus, Ferocactus wislizeni. There are lots of species of barrel cacti, but wislizeni is the most palatable. It looks unappetizing because of the dense spines, but almost every part of the cactus is edible!
The fishhook barrel cactus (Ferocactus wislizeni) is named for its long spines that curve at the end. This cactus can tolerate temperatures as low as 5 degrees Fahrenheit and is hardy in USDA zones 7 through 10.
The Ferocactus are one of the cacti that we can most easily find in nurseries. They are very easy to care for and to get, to the point that if we sow ten seeds, it is most likely that we will obtain a percentage of Read more
Germination can take place from 1 week to 5 months depending on growing conditions and quality of seed. Once the seeds have germinated, give them filtered light or partial shade. They need as much time in the light (not direct) as possible. 16-18 hours is Read more
Ferocactus viridescens. Habit: Perennial herb, shrub, tree, generally fleshy.
The Ferocactus peninsulae can be grown in full sun or light shade exposures; it needs a warm and dry climate. They resist light and occasional frosts if the substrate is dry. The soil can be a mixture of 50% leaf mulch and 50% coarse siliceous Read more
In its native habitat, F. chrysacanthus runs the gamut between desert, hills, valleys, and coastal regions. Although it seems like it could grow almost anywhere, it gravitates towards areas of poor soil that never get waterlogged. Of course, the other constants are plenty of sunshine Read more
