Ferocactus latispinus is a modest-sized barrel cactus and probably the best-known of the ferocacti.
Ferocactus latispinus is a relatively easy species. Slow growing to start but does well under cultivation. Growth rate: TSlow growing to start but does well under cultivation. Soil: Grow it in a rich and particularly draining substratum, as it is very sensitive to rottenness when in presence of humidity and low temperatures and let the soil dry out between waterings. Repotting: Repot in the spring, when their roots become cramped. Generally, they should be repotted every other year in order to provide fresh soil. After repotting, do not water for a week or more. Use pot with good drainage. Fertilization: It grows much faster with a low nitrogen content fertilizer in spring and summer. Watering: Water during the aestival growth cycle from March till October, the thin, fibrous roots suffer if there is humidity, therefore the plant should be watered only when the surrounding terrain is dry. But needs to be avoided wetting the bodies of these plants while they are in sunlight. A wet cactus in the sun light can cause sun burning which can lead to scars or even fungal infections and death. Keep dry as soon as the temperature starts dropping in October and keep it perfectly dry in winter at temperatures from 5 to 15 degrees centigrade. Preferable not to water on overcast days, humid days or cold winter days. Hardiness: They need to be kept in a cool place during winter rest and can tolerate sporadic light frost if kept on the dry side prior to, and during, cold weather with little danger of being killed. However in cultivation it is better not to expose it to temperatures lower than 5° C, even if in an aerated and protected location. It tends to rot in winter during the resting phase, if kept wet. In the rest period no high atmospheric humidity!! Outdoors this plant is very adaptable, as long as you avoid excessive humidity in the winter months. Sun Exposure: It need full sun exposures with ample airflow for best appearance.
