Coast Barrel Cactus Ferocactus viridescens
ABOUT
The plant commonly known as the fishhook barrel cactus has a distinctive shape that is cylindrical and resembles a barrel. It is named for its curved spines, which resemble fishhooks. The surface of the cactus is ribbed, with protruding ridges running vertically along the plant's body. Between these ridges, the cactus is adorned with areoles, which are small, cushion-like structures from where the spines and flowers emerge. The spines themselves come in different shades, from yellow to red or even gray, and vary in length, providing the plant with a unique texture and appearance that can appear almost bristly. The fishhook barrel cactus is also known for its vibrant flowers, which tend to be a radiant yellow or occasionally red, sitting atop the cactus like a crown. These flowers bloom in ring clusters and can add a pop of color, contrasting sharply with the green of the cactus itself. Additionally, the fruit of the fishhook barrel cactus is shaped like a barrel and remains attached to the plant, offering a visual treat with its bright yellow or red hues when ripe. The overall appearance of the fishhook barrel cactus is striking, with its combination of formidable spines, colorful flowers, and fruits set against the backdrop of its robust and hardy green body.

WaterThe Coast Barrel Cactus should be watered deeply but infrequently. Allow the soil to dry out completely between waterings, which typically means watering every two to three weeks during the active growing season in spring and summer. In the fall and winter, reduce watering to once a month or less, depending on the humidity and temperature in your area. When you do water, provide enough water so that it runs out of the bottom of the pot, usually about a quart for a medium-sized pot. Over-watering can lead to root rot, so err on the side of underwatering rather than giving too much.
LightThe Coast Barrel Cactus thrives best in full sun conditions, so place it in a spot where it will receive direct sunlight for at least six to eight hours a day. In an indoor setting, a south-facing window is typically the ideal location for maximum light exposure.
TemperatureThe Coast Barrel Cactus can tolerate a wide range of temperatures but prefers warmer conditions. It can survive temperatures as low as 25°F but thrives in temperatures between 70°F and 100°F. Protect it from frost and extended cold weather to prevent damage to the plant.
PruningPruning is generally not required for the Coast Barrel Cactus, as its natural shape is typically maintained without intervention. If necessary, remove any dead or damaged spines or portions of the cactus to maintain its appearance, doing so carefully with proper gloves and tools. The best time for any pruning would be in the spring before the growing season begins.
CleaningAs needed
SoilCoast Barrel Cactus prefers a well-draining soil mix consisting of 50% pumice or perlite mixed with 50% cactus potting soil to ensure proper drainage. The ideal soil pH for this cactus should be mildly acidic to neutral, ranging from 6.0 to 7.5.
RepottingCoast Barrel Cactus should be repotted every 2 to 3 years or when it outgrows its current container to provide fresh soil and prevent root crowding.
Humidity & MistingCoast Barrel Cactus thrives in low humidity environments typical of arid regions, and does not require high humidity levels, making it well-adapted to indoor air conditions.

Life cycleThe life of the Coast Barrel Cactus (Ferocactus viridescens) starts with the germination of seeds, which is heavily dependent on the right temperature and water conditions. After germination, it enters a juvenile phase, characterized by slow growth and development of its characteristic ribbed, barrel-shaped body and spines. As it matures into adulthood, which can take several years, the plant increases in size and may begin to produce bright yellow flowers at the crown during spring or summer. These flowers are pollinated by insects and possibly birds, leading to the development of fleshy fruits containing seeds, which on maturing, are dispersed by wildlife. In its adult stage, the Coast Barrel Cactus can withstand extreme desert conditions, going through cycles of dormancy and growth as seasons and water availability dictate. This cactus has a long lifespan, often living for several decades, with some specimens surviving to over a hundred years.
PropogationPropogation time
Spring-Early Summer
The most popular method of propagation for the coast barrel cactus (Ferocactus viridescens) is through seeds. The best time to sow coast barrel cactus seeds is in the spring or summer when temperatures are consistently warm, which is conducive to germination. To propagate by seeds, one should prepare a well-draining soil mix and place the seeds on the surface, then lightly cover them with a thin layer of sand or soil. The soil should be kept moist but not waterlogged, and the pot should be placed in a warm area with plenty of indirect sunlight. Seedlings will emerge in a few weeks to a few months, depending on the conditions. After the seedlings have grown enough to handle, they can be carefully transplanted into their own pots to continue growing into mature cacti.
