Barrel Cacti are the classic desert denizens of lore. There are two genera, Echinocactus and Ferocactus. The cacti in the genus Echinocactus have a fuzzy crown of fine spines, while those in the genus Ferocactus are ferociously thorned. Each can be grown as a houseplant or in an arid garden in less common situations. They are attractive additions to a succulent display.
Barrel Cacti are characterized by their ribbed cylindrical shape. They come in many sizes and may be low and squat or as tall as 10 feet (3 m). Barrel Cacti care for lost travelers in the desert because they habitually grow tilted to the southwest. Caring for Barrel Cacti is quite easy, making them great plants for the beginning gardener.
Growing Conditions and General Care
Potted Barrel Cacti should be kept in the warmest room of the home in a bright, sunny location. In the height of summer, direct sunlight may burn the plants, so you should move them back from the window or turn the slats on your blinds to diffuse the light.
The soil for Barrel Cacti is mostly sand with a bit of topsoil, perlite, and compost. Prepared cactus mixes are suitable for growing Barrel Cacti. Unglazed pots are best for potted cacti because they allow excess water to evaporate.
Water is a very important component of caring for Barrel Cacti. These plants are native to arid desert regions and usually rely on rainfall to meet their moisture needs. Therefore, water your Barrel Cacti once per week in the summer. These cacti do not need much water in winter when they are dormant. However, adequate spring water may cause the plants to produce large yellow flowers. Then, rarely, they will grow edible fruit.
Barrel Cacti naturally grow in low-fertility areas, so their nutrient needs are low. Fertilize your Barrel Cacti once a year in spring, when they emerge from dormancy and begin growing again. A low-nitrogen liquid fertilizer is a good formula for Barrel Cacti. The amount of fertilizer will depend on the size of your container and plant. Consult the packaging for guidance on the exact amount.
Growing from Seeds
Barrel Cacti can be easily grown from seeds. Fill a flat with a commercial cactus mix and sow the seeds on the soil's surface. Sprinkle a thin layer of sand over the seeds. Then the soil needs to be evenly misted. Cover the flat with a lid or plastic wrap and keep it in a warm location. The seeds readily germinate and can be transplanted into a larger container once they are large enough.
