How to Grow and Care
Goat's Horn Cactus is a desert cactus. Therefore it loves the sun and will grow well if provided with plenty of direct sunshine. However, young specimens should be provided with indirect sunlight. Inadequate light could result in poor growth and unnatural shape.
Use alkaline, lime-based soil with good drainage as this species is rot prone.
This cactus thrive in average room temperatures between 60 and 75 °F (16 and 24 °C ) from spring until fall. Then, from late fall to late winter, give them a rest at temperatures between 45 and 50 °F (7 and 10 °C).
Normal indoor humidity is fine for Goat's Horn Cactus. Provide good air ventilation for healthy growth.
During the active growth period, water this cactus moderately but allow the top 3/4 of the mixture to dry out thoroughly between waterings. During the rest period, give only enough water to prevent the mixture from drying out.
